Some malfunctions in the operation of the boiler may be caused by incorrect parameters in the settings of the service menu. This can happen, for example, after unskilled intervention or ... as it once happened in my practice, after pouring water on the boiler board.
Of course, first of all, the service menu is used for setting, adjusting and diagnosing the operation of the boiler. In this article I will share how to enter the service menu of the Ariston Class 24 FF boiler and how to change the parameters, as well as give the values that were set in my boiler from the factory.
Before proceeding with any settings, it is important to carefully consider the structure of the menu, as well as understand whether you need to intervene and change any parameters. Incorrect intervention can lead to serious malfunctions. For example, there is a parameter that is set depending on the version of the boiler and is used by specialists when replacing the board.
Considering all of the above, you should understand that some of the parameters given by me as "Factory settings" may differ from the ones you specifically need, and therefore you carry out all these movements and settings at your own peril and risk.
Fast navigation through the article
At first it may seem complicated, but as you figure it out, everything will be simple and clear, so:
Each parameter is identified by a three-digit numeric code. For example 228 (this is just the parameter code that depends on the version of the boiler)
The first digit of the three-digit code means a separate menu group, the boiler has six separate menu groups, each responsible for its own section of settings. Here they are.
2 - Boiler settings
3 - Solar collector and storage boiler
4 - Zone 1 parameters
5 - Zone 2 parameters
7 - Testing and maintenance
8 - Technical parameters.
The second digit of the three-digit code denotes the submenu, and the third is the parameter itself to which access is opened.
For example, the code 228 already known to us is deciphered as follows: 2 - Boiler settings (this is Menu), 2 - Basic boiler settings (Submenu), 8 - Boiler version (Parameter).
So by typing the three-digit code 228, we get access to the set value of this parameter, which, according to the table, can vary from 0 to 5 and depends on the version of the boiler.
I will provide tables with menu codes and a description of what is regulated by a specific code below, but for now, let's figure out how to enter the boiler service menu.
For all manipulations with switching modes, only 4 buttons are involved - Plus, Minus, Ok / Menu, ESC.
It is important to understand that not all boiler menu items will be available to you, some of them will only become available when connected to the boiler. additional devices, for example external sensors or solar collector.
And most of the menu items are available only by the service code, I'll talk about this below, but for now let's "practice on cats"
Our kitties will be open to free access values. But first, read how to work with the menu.
Having pressed the "Ok" button once, the number 2 will flash on the digital display - this will be the first digit of the future three-digit code (Menu group number)
Using the plus and minus buttons, you can change this value from group number 2 to any other group. To fix the selected group for further entering the code number, you need to press "OK" again - after that the second digit of the future three-digit code starts blinking (Submenu)
Having selected the submenu, we fix it by pressing the "OK" button again and in a similar way select and fix the third digit (Parameter)
Everything! Now the screen will no longer display the three-digit code itself, but the set value of this parameter, which can be changed by pressing the "plus" "minus". Having made the necessary changes, do not forget to fix them by clicking "OK".
Please note that after selecting the desired menu, after a few seconds of inactivity, an alternate display of the three-digit code (to remind where you are) and the parameter corresponding to this menu will begin.
The ESC button is used to exit and the settings menu and return to the previous step. Exit is carried out step by step, one press is equal to one step back.
Now, if you want to practice, to better understand the switching order. For example, enter the menu code 701, this will turn on the forced air removal mode, in fact, you activate the pump in the boiler for 6 minutes.
When this mode is turned on, the symbol "Р I -" will light up on the display. You can exit the "Anti-air" mode without waiting 6 minutes if you press ESC.
Then, using ESC, try to go back and go to mode 300, which means (Set water temperature in the boiler) in the values, you can see the temperature that is currently set by the DHW regulator.
So, if you understand how to work in the menu, then it's time to move on to more serious things. The vast majority of all settings are protected from accidental interference with an access code. Therefore, in order to proceed with the boiler settings, we perform the following actions.
Press "OK" several times until the indicator shows the value 222 - Then hold the "Plus" until the value becomes 234 - then again "OK" - Everything is ready!
Now we have one number 2 constantly lit and another 2 blinking - What do you understand means the following - Menu 2 is on and you can select a submenu, and then a parameter. Having set the desired three-digit code and clicking "OK", we will see the parameter value that can be changed.
Use the ESC button to go back and go to the selection of other categories of menus and submenus.
The values added in the white boxes are the values used in my boiler. If there are no corrections, then I have the same values as the printed table. To enlarge, click on the photo of the table.
Table 3 He turned on the ariston bs 24 ff boiler in heating mode, set the coolant temperature to more than 60 degrees and the following began to happen - after the burner turns off, after 5 seconds crackles begin in the boiler, approximately in the upper part in the heat exchanger area. What is this malfunction? The boiler has been in operation for 2 years.
Maintenance was carried out, except for cleaning the inside of the heat exchanger from scale and other things! The technician who carried out the maintenance said that there is no need to descale! The device, as it worked 2 years ago, still works unchanged, except for crackling after the burner goes out, but only at coolant temperatures above 60 grams.
Carried out the installation and installation of the wall-mounted boiler Ariston. It works great for heating. On the hot water supply it turns on, heats up for about a minute and the flame turns off, green 40-80 are on, then the green 40-50 error and the yellow chimney "Alert for insufficient water under pressure" blinks. After which the flame appears and heats further, then turns off again.
The Ariston Uno boiler is set to summer mode. I turn on the tap hot water, the boiler is working normally (heats the water). After turning off the hot water, gas is ignited on the radiator circuit, and the boiler continues to heat the water already in the system. After a while, he either stops (it seems as if he "remembers" that he is in summer mode) or make attempts to re-ignite the gas to the heating system. But he can't do it.
Most likely, you will have to reflash the program memory.
Installed a gas boiler Ariston Uno 24 MI. At first it worked fine, but about 3 months ago, problems began, first with hot water, and then with heating. During ignition, the boiler ignites, but the ignition clicks are heard for 7-10 seconds, and then the protection is activated, the boiler goes out, the red light is on. After pressing the restart button, it lights up and works fine. Previously, it was 1-2 times a day and only when hot water was turned on, but now it is constantly. Tell me what could be the problem?
Clean the flame control electrode with a zero, it must have become covered with soot. Do not know who is responsible for the control - it will not hurt to clean everything that is in the combustion chamber above the burner. Well, if it doesn't help, then the fee.
What is the reason for the blocking of the Ariston UNO 24 MFFI boiler when the heating is turned on? Moreover, the blocking occurs approximately after half an hour of operation - when the batteries are fully warmed up. I thought maybe the temperature sensor, but the indicator "says" the ignition.
It is necessary to pay for the repair, it is not necessary to change it.
The boiler Ariston Uno 24 MFFI EE is faulty - the yellow lamp turns off and lights up. How to fix?
Check the operation of the turbine.
Check the pressure switch.
Check the functionality of the email. boards.
The Ariston Uno 24 boiler operates in heating mode and periodically turns off. with extinction of all diodes. When incl. its on a button incl. it starts, for a while it can work for an hour or half an hour and off. It seems to me that the fee.
Recently carried out repairs. Did the following.
1- cleaned the air vent valve. Didn't work completely.
From this, in the heat exchanger, due to the presence of air, the scale turned into some kind of black flakes. (local overheating affected).
2- flushed both heat exchangers. The secondary was 90 percent clogged.
I did the second operation twice. But I think I'll have to repeat it in the spring.
3-flushed the filter on the return line.
It looks like the secondary heat exchanger is clogged with scale, overheats and turns off. Need to rinse!
The gas boiler Egis Plus 24 FF is in operation. The pressure in the heating circuit dropped by 0.5 atm for two weeks. I checked the expansion tank, it was zero. Pumped up to 1 atm. Now it began to fall more slowly, the pressure in the expansion tank is normal. For what reason can there be such a drop in pressure in RB? Outwardly, he is whole, the air does not poison. Basically, the pressure in the heating circuit drops after using hot water. At
pumping closed the taps for supply and return. I drained the water from the boiler, it spilled out a little when I pumped it up. Before that, the season worked fine.
If you are sure that the heating circuit is falling, then look for a leak in it.
Installed and connected Ariston Egis Plus 24 s open chamber combustion.
There is a problem, advice is needed:
1. The temperature in the DHW circuit does not depend on the set parameters and is always maximum. Regulated in the heating circuit.
2. Feeling that the boiler does not change the intensity of the flame (in both modes). It lights up at maximum and works like this until it turns off when the maximum temperature is reached. Is it customizable in some way or something more serious?
First you need to look at the gas valve settings.
The boiler generates error 104 during heating operation. The pressure in the expansion vessel is 1 bar. the pressure in the 1.4 bar apparatus does not drop, the bypass is normal, the turbine and everything else is also normal. Everything is clean along the contour. What can the third digit mean in the error? Boiler Ariston Chimney class. And if we have a pressure sensor? I didn't find it.
If the error is only when working for heating, most likely, the malfunction needs to be looked for in the heating system, I would start by checking the CO filters. Most often not, but there were instances with a pressure sensor. Check menu 247 to be correct and set 0 if necessary.
We made the installation and launched the Ariston Clas System 15 FF wall-mounted boiler. During operation, it gives an error 104. Pressure in the expansion tank 1. The pressure in the boiler 1.5 does not drop. The filter is clean. There is no air in the CO. The heat exchanger is flushed clean. What could be the malfunction? It stops 3-4 times a day. I noticed that when an error occurs, some hiss and a pressure surge from 1.5 to 1 and again to 1.5 becomes and error 104 appears.
Options: board, pump, NTC.
Tell me, must the coolant be drained before air injection?
We drain (bleed through the vent) the coolant until the pressure gauge shows 0. Before that, shut off the CO cocks under the boiler. Then we pump the pressure into the air part with a pump. expansion tank checking the pressure with a third-party pressure gauge. We pump up 1.0-1.2 bars. We open the taps. Then we pump it with pressure in CO, control the pressure with a boiler pressure gauge. We pump either through the make-up tap or by third-party
pump at the CO filling point. We pump up to 1.3 -1.5 bar. We check if the air vent is open. We turn on the boiler, and if there is a mode for removing air from CO, then we drive the device in this mode. We also warm up the CO to the maximum. Air is removed from CO. We pass by heating devices and through the tap of Mayevsky we bleed the air out of them. The pressure will drop slightly. We feed up to the values indicated above. Everything. If everything is correct, then at
heating to the maximum temperature, the pressure in closed system will not rise more than 0.3 bar.
Malfunction double-circuit boiler ariston egis 24 ff - when hot water is turned on for 20 seconds of operation, the flame goes out and error 109 lights up the plausibility test failed. What is it and how to fix it? First, the burner goes out, and then 109 comes on. DHW temperature is the temperature of the water in the tap? Can I make repairs myself?
Choose one of the options:
1. Error 109 lights up and after that the burner goes out;
2. The burner goes out and then error 109 lights up;
Set the DHW temperature to 50 degrees or less and see if there are any changes.
Tell me, where is the expansion tank on the Egis 24FF gas boiler, and more specifically the pumping valve? And how to properly drain the water from the boiler? To correctly pump up the pressure into the expansion tank.
Located at the back, above the boiler.
- Close the entrance tap cold water into the apparatus.
- Open a hot water tap on the mixer at any point of the tap.
- Open the make-up tap.
- Wait until the pointer of the pressure gauge reaches zero.
The problem in the operation of the double-circuit boiler Ariston BS II 24 CF. When the heating is turned on, the burner starts up and turns off after a short time, the system does not warm up completely, and the device is already turned off. They called the foreman, he said that the pump was out of order, although when the boiler was turned on, a slight vibration was felt and the supply pipe heats up and the first three radiators too (the remaining three were not possible to check). But
the return line is slightly warm. The boiler does not issue errors. Tell me how you can check the pump's performance?
Turn off the boiler using the button and from the socket; turn off all the taps, drain the water from the device through the drain fitting, cover the board with some kind of waterproof oilcloth on top to prevent water from getting in, remove the pump and try to turn it by hand - how easily it turns.
1. the return filter is clogged.
2 the filter in the boiler is clogged (the pipe where the pressure gauge comes in).
3 the heat exchanger is clogged.
4. the pump does not reach the operating parameters.
Aegis plus 24 FF boiler is in operation. When I turn on the hot water supply, the device turns off after 30 seconds and displays error 303. Tell me, what could be the damage?
Most likely, you will need to change the board.
The boiler Ariston BS 24 FF was installed, it worked for 4 years without breakdowns. Now there is a problem: You set the temperature, for example, 70, the boiler does not heat up the entire system, although everything was normal before. Only the first 3 batteries are heated, respectively, the return flow cools down, the device turns on for a short time (the sensor on the dial shows a maximum of 40) and the heating is turned off, although the return flow is slightly warm. I don't know what the problem is, maybe you need to install an additional pump? (The stabilizer is worth it, the filter is only from mechanical impurities.).
The filter in the boiler is clogged.
We are going to connect a 15 kW single-circuit wall-mounted gas boiler Ariston. Does it need an expansion tank? How to check the boiler after starting up?
This model already has a standard expansion tank, but its volume is not always enough for work. We need to inspect the heating system. If it is large enough, then it will be necessary to embed an additional tank outside the boiler. Before starting commissioning, fill the heating system with water, including underfloor heating and radiators, and ensure that the chimney is ready.
The Ariston boiler is in operation, which works from a cylinder with liquefied gas. Recently, it has become scary to turn it on: the volume of the flame soars up high. How can you fix and repair?
It is necessary to see why there is no flame control, and what is out of order - a reducer or a flame regulator, or there is another reason for this phenomenon.
Boiler malfunction Evo class. Suddenly stopped turning on, only the fan works without stopping. Shows errors 201 and 607. Can this be fixed?
Error 201 means a short or open circuit in the hot water circuit temperature sensor circuit. Error 607 is the pressure switch contacts are closed before the fan turns on.
In Egis Plus 24, the heating mode was turned off, only hot water was left. It became impossible to start it: writes "Board failure". How to make repairs yourself?
Measure the potential between zero and ground, there should be nothing. If the voltage is at least 2-3 V, then the boiler will write an error and the potential must be removed. Then you should find out the voltage in the network: at 180-190 V, the board will also fail. If everything is in order, then the problem is in the board itself.
Ariston Genus 24 is connected, the error "flame separation" began to appear. How is this eliminated?
The gas pressure in the boiler is clearly too high. The gas valve should be adjusted. There may also be a problem with the air supply to the boiler.
Double-circuit boiler Class 24 has stopped giving hot water, error 103 is displayed. What can you do yourself?
This error code indicates insufficient circulation of the coolant. The water pressure in the DHW circuit should be checked, if it is low, then there may be a leak. If the make-up gives nothing, or gives a short-term effect, you should call a specialist.
When you open the hot water tap, the wall-mounted gas double-circuit boiler Ariston Class 24 turns on, d38 is displayed on the display, and after 2-3 seconds. 5P3 appears and immediately again d38, after 2-3 seconds again 5P3 and immediately again d38. And so the information on the board changes during the first 20-25 seconds. heating water. Then the water heats up without problems and d38 is constantly on the screen. It started after they stopped heating the house, that is, the boiler
works only for heating water. This is the first question. And the second: After closing the hot water tap, error 104 lights up on the display. The boiler starts up only after pressing RESET. What could be the cause of these problems?
There was the same malfunction. We decided to flush the secondary DHW heat exchanger. But you have to flush every six months. The symptoms were one to one. Yet. There is a special device for flushing, it is connected to the input / output of the DHW circuit. If you use it every six months, then such a rinse is sufficient. If the heat exchanger is heavily contaminated with deposits, then it is necessary to remove the heat exchanger and "soak" it in a solution with citric acid (vinegar).
We installed and started up the clas evo 24 ff boiler. A malfunction has occurred. The boiler does not pump the heating system, the first two radiators are warming up. Heating polypropylene. At the same time, it does not give any errors. What could be the problem? I also want to add that the temperature quickly builds up for about one and a half minutes and the boiler goes out.
There is no circulation of the heating system, there may be a blockage or the transport plugs from the radiators may not be removed, there may be air both in the pump and in the system.
The gas boiler Ariston clas system 24 ff was put into operation. When starting up, the boiler does not always ignite, it is clear that there is a spark, a certain amount of gas flows (I noticed the meter readings), but the flame does not ignite. After 8 seconds, as expected, error 501 is displayed. Sometimes, at the moment of ignition, you can see how a small flame flares up and goes out, sometimes it ignites without problems with a normal flame. I also noticed that the flame on the burner happens
different strengths. I thought that this was due to the temperature of the coolant, but with several switching on and off of the boiler, the flame is different at the same temperature. The boiler was installed what is called "as is", i.e. no parameter settings have been made. The only parameter that tried to change this parameter 220 "Smooth ignition" - the factory setting is 47, tried to increase it to 80 - did not give a result, returned it back.
I did not change any other parameters. I also noticed that when the temperature setting is increased to 61 degrees, the device does not turn off, i.e. it gradually reduces the flame as it approaches the temperature and continues to burn in this mode. When the temperature was set to 53 degrees, it heated up and turned off, but then it could not start due to the above problem. Find a specialist for such boilers in our outback
impossible, and the nearest center is 200 km away. Maybe someone faced a similar problem? Please advise what test operations need to be done to identify the malfunction.
It is necessary to slightly increase the minimum gas pressure on the gas. valve. Warming up to the set temperature takes place for min. pressure. DHW control (knob) - to the maximum. The flow must correspond to the maximum (12 l / min). The first measurement (by gas) at the inlet, in static, then at start-up. If the pressure drops below 14 mbar, do not touch the valve, otherwise you will lose all factory settings.
Tell me, I have a wall-mounted gas by-pass boiler Ariston Class 28 CF installed. When DHW is turned on, the water temperature does not correspond to the temperature set on the screen. At first I didn’t pay attention to it, but lately the readings are very different, I set 45, but it flows, about 38. How to fix it? Can I carry out repairs myself?
Need inspection and maintenance with complete cleaning done.
After switching on the boiler (in heating and hot water mode), the green LEDs 50/60/70 and the yellow LED house light up, the boiler does not ignite. What to do?
This error is the presence of a flame when the gas valve is closed (false flame). The board needs to be repaired.
I have a wall-mounted boiler EGIS II 24 FF connected for three years of operation. During the year, the fan relay failed several times, what is the reason? The fan runs constantly!
Sticky contacts. Perhaps the propeller rotates hard, because of this, the current through the contacts is too high. Try to put a relay with a high current. (More than it was) the current is indicated on the relay case. Also check the contacts of the fan connector on the board and the contacts on the fan itself - perhaps somewhere the contact is not very good, because of this, the relays do not work for a long time. In boilers of this series, resetting this parameter (protection against
water hammer) is not provided for any of the three modifications of the control board.
The boiler is new. For some reason, the DHW circuit does not work. The heating is working properly. On an attempt to turn on hot water, the boiler only shows the temperature, and is not even going to heat, it waited about 5 minutes.
The problem is in the 3-way valve. The caliper let the water in - ruined the mechanics of the servomotor. You need to change both.
Installed wall gas boiler BS II 24 CF NG. When DHW is turned on, the yellow lamp (t-40) first comes on, and then it starts flashing. The water heats up normally, the heating works, in general, everything works. Should the light be blinking or some kind of system malfunction. When heating and DHW are on, it is on, not blinking. I was told that it should not be so, it should just burn. The boiler was installed just now, we are afraid of failures in winter period.
The boiler was installed this spring, there were no problems. Now a rather strange breakdown has occurred - an error 5p3 (flame separation) appears. Moreover, the error appears only if the temperature of the heating circuit is set below 60 degrees (the device tries to start, ignition is heard, the burner icon appears on the panel for a second, then it disappears and an error pops up). If I set it to 60 degrees or more, the problem goes away. What could it be?
This 5P3 error on these boilers may occur due to the pulse power supply installed there. The potential that the ionization electrode sees arises as a result of combustion meets the potential of the boiler itself (which will be more than 5V) if it is not grounded, this error may occur. The technician can check this by disconnecting the ground wire from the main control board and restarting the boiler at your desired temperature. the error should be gone. If this does not happen or your boiler is grounded. Then you need to look at the settings of the gas valve.
The gas boiler Ariston Egis plus 24 FF is in operation. When the hot water tap is opened, cold water starts to flow almost immediately after opening, then hot for 20 seconds, and again cold, again hot for the same approximately 20 seconds, and again cold, and this continues indefinitely. On display gas boiler err 109 is displayed, judging by the instructions this is some kind of "plausibility text failure". Can you tell us what this test is than
an error could be caused, and how can I fix the problem?
The boiler needs maintenance.
Tell me about connecting a room thermostat to the boiler. He did everything according to the scheme that came with him. To begin with, I threw off the jumper, the boiler did not start - this is normal! I connected a room thermostat, the device did not start, but when I turned the knob, somewhere more than 23 degrees, there was a click in the thermostat, the boiler started to work, but it turns off and on without responding to the thermostat. I tried to throw on the thermostat
terminals, on the contrary, the device turns on up to 23 degrees, when you turn the thermostat knob, a click and the boiler turns off, but in this position it does not respond to the thermostat. Who knows, tell me, maybe I'm doing something wrong!
Probably turns off due to overheating of the coolant above the ordered temperature. Add the boiler temperature.
Double-circuit gas appliances make our life more comfortable and enjoyable. They are quite practical to use, suitable for heating country houses, and small apartments... They are used for heating industrial or warehouse buildings, the area of which is not more than 500 sq.m.
The advantages of Ariston boilers are that, in addition to heating buildings in winter, they heat the water used in everyday life. all year round... It is quite convenient and does not require the installation of additional equipment.
The description of Ariston gas units must begin with the characteristics of their main part - the burner. This element is used to burn fuel and to transfer thermal energy to the heating system.
Types of boiler burners:
The modulating burner is more convenient to use. It provides for automatic power regulation depending on the temperature of the device.
By branch type combustion products, burners are divided into:
Units with a closed burner are safer to operate. In this case, the combustion products of natural gas do not enter the room. The use of a chimney is not required. The device is simply connected coaxial pipe and take her out.
The design of the coaxial pipe provides for the presence of two layers, which ensures the simultaneous removal of waste and the flow of air from the street into the burner.
Equipment with an open burner provides for the mandatory use of a chimney to remove combustion products.
Ariston boilers are used for heating and heating water, that is, they are double-circuit
A distinctive feature of Ariston boilers is their high quality. After all, the name of the company is translated from Greek as "the best".
Her products are especially popular with middle-income consumers. Gas boilers of this brand are purchased for heating rooms up to 500 sq. The company's products are universal. The transition to liquefied fuel is carried out only by replacing the burner.
Two-circuit wall-mounted gas appliances are practical to use. It is represented by three lines, each with its own modifications.
For all modifications of boilers, the following is common:
Gas boilers of various modifications differ from each other in structure, the common thing is their low cost and high-quality performance of parts.
Basic configuration of units from Ariston:
Let's take a closer look at the existing types of Ariston equipment.
The Ariston Genus line includes the Evo and the more expensive Premium models.
The Evo model is a two-circuit gas appliance with both types of burner: open and closed.
Genus Premium condensing boilers... Used for heating residential buildings and commercial buildings. Power range from 24 kW to 35 kW.
Existing modifications:
This model is adapted to work in harsh climatic conditions. Normally withstands gas pressure differences. The device is equipped with a collector into which the condensate flows. This ensures operation at temperatures below 50 degrees.
> Cost of Ariston boilers
The average cost of Ariston Genus boilers is 54,000 - 72,000 rubles, Ariston Clas - 25,000 - 34,000 rubles, Ariston Egis - 27,000 - 34,000 rubles
Ariston products can be found in catalogs. There are many models gas appliances... The main mistakes when choosing the wrong unit are made from a lack of information. Therefore, before visiting the store, you should familiarize yourself with the basic tips for choosing a wall-mounted gas appliance.
When choosing a boiler, take into account the following points:
The most demanded among Ariston boilers are wall models by 24 kW. During the operation of the gas boiler Ariston, malfunctions and malfunctions may occur, like any other technique. The list of error codes is given in the instructions in the form of a table. Some of them are a malfunction in the operation of the automatics (cause a protective shutdown of the device) and are eliminated by pressing "Reset", and some signal faults and interference in the operation of the boiler and require intervention (block the operation of the system).
All codes are divided into six groups according to the number of boiler units. The first value denotes the node in which the failure occurred, the rest - the error code, but it should be noted that if the security error is repeated frequently, this indicates a malfunction.
The most common ones are:
Ariston Clas Evo boiler control panel
Error 101 means overheating, a sensor has been triggered, after cooling down, the boiler starts up. The reason may be the accumulation of scale in the heat exchanger, as a result of which the flow decreases and the temperature increases, or interruptions in the operation of the circulation pump. Flush the heat exchanger, adjust or change the pump. Sometimes the reason may lie in the increased gas supply, screw on the valve, if it does not help, you need to adjust the gas valve.
Error 103, error 104, error 105, error 107 occur when there is a violation of the circulation of water in the circuit, its absence or low pressure. This happens when air has accumulated in the system, to remove it in the Ariston Egis Plus 24 boilers, press and hold the mode button for 10 seconds. On boilers Ariston Mathis and Ariston UNO, hold the rezet button for no more than 6 seconds. The pump will run for 5 minutes without igniting, removing air from the system. then check the pressure, the norm is 1-1.2 bar, if necessary, increase.
Ariston Egis Plus 24 boiler
Error 108 appears when insufficient pressure water in the heating circuit. Why the pressure drops - the cause may be a leak from the heating radiators, you should check the joints in the pipes. During the heating season, it will not be easy to notice a small leak, since a small leak will evaporate on hot batteries. It is necessary to turn off the heating and add pressure up to 2.5 bar to determine the place of the leak.
The next reason may be the leakage of the heat exchanger pipes. To eliminate it, you can solder the heat exchanger, if soldering is not possible, it needs to be replaced. The expansion tank may depressurize or the membrane in the expansion tank has become unusable - seal the tank or change the membrane.
The tank itself may leak - you can determine this by pressing the spool in the upper part of the tank. If this causes water to spill out, change the tank. How to raise the pressure - you can use a homemade original device consisting of a plastic bottle, a tap and a spool. On a plastic bottle, on a lid, cut a thread with a tap so that you can fix a tap on it.
Drill a hole on the back to secure the spool to it. We put the spool inside the bottle and fix it. We fill the bottle with water, close the tap and connect the heating system to it through a hose, connect the pump to the spool and, by pumping it, pour water into the heating system. The procedure for pumping water into the system is repeated until the pressure is normalized, up to 1.5 atm.
Error 109 appears when overpressure above 3 Bar and is considered one of the infrequent occurrences. To eliminate it, you need to relieve the pressure, as prescribed in the instructions for the device, using the Mayevsky crane. if this does not help, most likely the cause lies in the secondary heat exchanger.
When a partition collapses inside the heat exchanger, it can be a fistula in it, mixing with liquids begins. Water from the mains, which has a higher pressure, begins to flow into the heating system, as a result of which the pressure rises. What to do if this happened - removing the fistula or replacing the heat exchanger will help solve this problem.
Error 117, according to the instructions for the Ariston BS 24 FF unit, means insufficient circulation. To eliminate it, press the reset button, in this case the system will check and adjust the temperature difference at the inlet and outlet of 3.5 degrees in 8 seconds.
Reset button on the Ariston boiler - "reset"
If the circuit is broken or the sensor is short-circuited on the supply to the hot water supply circuit, error 201 appears.Check the contacts, they may have oxidized, or the wire has come off, or the sensor itself is faulty and it will have to be changed.
Error 302 appears on the display when there is no circuit between the control board and the display. The reason may be a violation of the contacts or their oxidation, in which case the contacts should be connected or cleaned. The control board may also fail - replacement is required.
Error 303 means a malfunction of the main control board, the solution to the problem can only be its replacement.
Error 304 also appears in the event of a malfunction of the control board and appears if more than 15 resets are performed within 15 minutes.
Boiler board Ariston
Error 307, error 308 also appears in the event of a malfunction of the control board, pressing the reset button will help to correct the situation.
The 501 code is described above in the section on most common errors.
On Ariston Egis Plus 24 models (Ariston Egis Plus 24) CF, class 24 FF and others, with an open combustion chamber, error 601 means no thrust. The sensor blocks the operation of the column in the event of interference in the smoke exhaust system.
This blocking is temporary, after 12 minutes the system will go into operation if the cause is eliminated, otherwise it will repeat again. To eliminate, clean the chimney, if the chimney is free, check the serviceability of the draft sensor.
Error 604 occurs when the fan speed is low or the Hall sensor is malfunctioning. The fan and sensor should be checked; if a breakdown is found, replacement is required.
Hall Sensor
The description of the cause of the occurrence and the remedy is described above, in the most frequently repeated errors.
Error a01 blocks the operation of the boiler due to a failure of automatic ignition. It can occur at low unstable voltage in the network, install a stabilizer. The polarity can also affect, in some cases the problem can be eliminated by changing the polarity in the outlet, turn the plug over, changing the phase to zero.
In addition, there may be problems with the flame ionization sensor.Check if it is clogged, not bent, the wire connecting the sensor to the board may be broken or oxidized. Solder or strip the wire.
Error e34 means a failure in the operation of the pneumatic relay when the fan is running. What to do - Check the relay and replace if necessary.
Error e108 means a drop in pressure in the heating circuit. The cause and solution of the problem is described above in the description of code 108.
The sp2 (5p2) error means that the second ignition attempt is unsuccessful. If the boiler does not start, there may be several reasons - there may be a problem in the ionization sensor, low gas pressure, insufficient air flow, removal of combustion products. Check the operation of the sensor, the gas valve may be closed or not open enough, open the window and the door, check if the chimney is clogged.
Ionization electrode
This DTC is described in frequently repeated errors.
Error 1p1, 1p2 (ip2) appears in case of poor water circulation or lack of it. Causes and solutions to the problem are similar to code 108 and described above.
Error 6p1 appears when there are problems with the air supply and smoke removal, the relay is delayed. to eliminate the problem, check if there is enough air in the room where the boiler is installed, if the chimney is clogged, if the relay contacts are stuck.
Error 6p2 also occurs in case of problems with smoke exhaust and air intake, while the contacts of the pressure switch of combustion products open during normal operation of the fan. The solution to the problem is the same as when the 6p1 code appears.
Boiler pressure switch Ariston
In addition to those described above, the following codes may appear:
Another reason may be that the blades of the impeller have worked hard, stuck to the body, this can interfere with rotation, replace the blades or the impeller itself.
The second reason in this situation may be the NTC sensor, to check its performance, measure the resistance at its contacts with a multimeter, if it is unstable, replace the sensor with a new one. If the safety valve leaks, the gaskets may be worn out, replace them.
NTC sensor
How to determine the error code if the device does not have a display or without a dial, such as on the Ariston BS II 24FF model? Such a device is equipped with indication lights, thanks to which you can determine the breakdown. So, for example, if the indicator 90 and the crossed out water drop icon are on, this means that the boiler has overheated and blocked. To eliminate it, you need to check the pressure switch and its connection to the board.
Gas boiler Ariston BS 24 cannot start. When you hold down the on / off button, the burner works. If you press the key, the unit immediately goes out. Tell me the reason for the breakdown?
Probably, the thermocouple is out of order or the gas valve is broken. There may still be a low gas pressure in the inlet pipeline. Sometimes there is a lack of voltage on the electronic board.
A problem has recently occurred. The start is very difficult. Igniter ignites, but there is no fire on the main burner. I just can't understand what is the reason?
Apparently, damage to the parts of the ignition unit. The unit must be serviced and the igniter must be cleaned.
Why did the Ariston BS 15 FF wall-mounted boiler stop turning off when the set temperature is being set? Heating goes up to 85 degrees, then it gives out a breakdown. After the restart operation, the cycle starts again.
Apparently, the board is not in order, the thermal sensor has a malfunction, the overheating protection button has broken. It is possible that there was a failure in the automation settings.
I would like to know why the boiler does not heat water above 70C? I need to set more, but the screen says that this is the maximum parameter. How to increase heating?
If the device does not increase the heating circuit temperature, the following factors can be assumed. In the settings, the maximum heating temperature is limited to no higher than 70C. A decrease in chimney draft is observed.
Ariston BS II 24 FF performs unsatisfactory functions in the mode of heating the DHW system. Cold and hot water flows out of the tap alternately. Tell me what is causing this malfunction?
Factors of the occurrence of the problem may be as follows. Cold water is mixed in due to the fact that the three-way valve has failed. The heat exchanger is clogged. You need to clean it up.
There is a tap under the boiler, and water leaks out of it regularly. The unit itself does not work. What do you need to do?
Apparently, there is a coolant discharge from the safety valve. This symptom indicates an increase in system pressure. In addition, the system make-up valve may be open, or the expander tank should be pumped up.
Explain why the pressure increases rapidly and at the same time the safety valve opens? The screen always lights up the heating icon in the heating cycle of the device. What to do?
There is a breakdown of the heating circuit temperature sensor. There is no normal circulation in the heating line.
What is the breakdown when the BS 24 FF gas boiler constantly turned off? Let's say that today the piezo ignition could not work at all. The boiler maintenance was done at the beginning of the month. What could be?
We can assume that there are malfunctions in the smoke exhaust device. You must perform a chimney inspection. Incorrect operation of the electric ignition will mean damage to any part in the event of a voltage drop or water ingress.
Please help me figure out the chimney? For 2 days, reverse draft appeared, while the smoke began to fall directly into the room. I made the chimney myself. It consists of metal pipe... It looks like there was a mistake in the calculations.
The boiler works fine on hot water supply, and when you turn on the heating, the water quickly comes to a boil, and the device stops working. What is the malfunction, and what is the way to fix it?
Perhaps the circulation pump is inoperative, the control board is faulty, the temperature sensor is faulty. It is also possible that the filter mesh is clogged.
At the DHW stage, the unit alternately began to issue either cold or hot water. Help me understand where this comes from. How to regulate water heating?
The heating system appears to be dirty or the heat exchanger needs to be cleaned. In addition, the pressure monitor may be defective or the circulation pump is defective.
The main reason may be the incorrect configuration of the chimney duct. Sometimes there is soot contamination that lowers its efficiency sufficiently. In addition, it is recommended to check the ventilation in the room.
The gas boiler Ariston BS is in operation. The device instantly sets the temperature up to 96 C, and then rises due to overheating. Later, when it cools down, it goes to reboot. How to fix the breakage?
Failure of overheating functions means that there is no circulation in the system. It is mainly necessary to control the position of the radiator valves. They need to be opened. After that, a check is carried out for contamination of the filter element, and it is also necessary to make sure that the heat exchanger does not contain dirt.
Carried out the connection of this unit in 2015. Approximately after 2 months, the device suddenly began to make noise. Explain why the noise is happening?
Most likely, there is scale in the heat exchanger. If the water is hard, then over time, lime will be deposited on the walls of the radiator pipes.
I am going to connect the Ariston BS II 15 FF boiler to heat the house. Please tell me what is the right way to put it into operation yourself?
For the correct start-up of the boiler apparatus, the following steps must be taken. We connect the power supply to the device. We open the gas tap. Then we start the burner device. Then adjust the desired temperature.
We want to carry out maintenance. Advise how to drain the coolant from the apparatus?
In accordance with the manual, this work is done as follows. Disconnect the device from the network. Close the gas valve. We open the automatic air vent. Open the drain cock. Then collect the spilled water. Alternatively, you can drain the water using the relief valve. This valve is located at the bottom of the apparatus.
Explain to me how to diagnose a 3-way valve? I think it does not open correctly. In heating mode, it weakly pumps distant batteries, however, the supply pipe heats up on the hot water supply heating water under the boiler unit.
That's right, it is necessary to inspect the three-way valve for the presence of acidification of the stem in an intermediate state. We also recommend diagnosing the heating system itself.
I have a BS 24 CF boiler in my house. Until that time, he performed functions properly. At the moment, after 1 minute after the start, the device goes out.
It seems that he is unable to force water into the system. Explain what is this reason? A likely factor for this damage may be the ignition electrode, which does not see the flame, or the lack of circulation.
Just yesterday, there was a problem with this unit. While working, he began to whistle. I tried restarting - it succeeded, but no changes occurred. Perhaps someone will tell you what the problem is?
Very often, a sharp whistle occurs when the pressure on the nozzles of the gas burner device is incorrectly adjusted. Check the gas pressure adjustments and correct if necessary.
The boiler has recently been filled with water, and the unit began to function with errors. For example, if you set any temperature, and the heating mode reaches only 22 degrees, and then the unit stops. Could you tell me what happened?
If water gets on the control board unit, it can be assumed that it does not work correctly. We advise you to reset it to zero by completely disconnecting the unit from the mains. Then turn it on again and test its performance.
The device of the same model was put into operation two years ago. Today, at the moment of start, the wick burns for 8 seconds, but the main burner does not support the flame, and because of this, the apparatus goes out. How can you fix a breakdown?
Probably, the automatic ignition is faulty or problems with the burner. In any case, it is necessary to check whether the phasing is not violated at the time of connection to the electrical network.
I carried out the commissioning of the same model myself in the middle of this year. After about 4 months, a malfunction occurred in the DHW circuit, but the heating mode is operating normally. I tried to open a hot water tap, but the device only displays the temperature, and does not even think about heating. Why is DHW not working?
Most likely, the 3-way valve is faulty. It needs to be replaced.
Tell me why the boiler is equipped with a safety thermal sensor?
This part shuts off the gas supply to the burner when the water overheats in the main heat exchanger.
The primary heat exchanger needs to be flushed and cleaned. Can you tell me what needs to be done in order to properly disconnect it?
The main heat exchanger can be easily removed from the boiler unit using an ordinary screwdriver. The following is the order of dismounting. We drain the water from the device using a drain cock. Then we empty DHW system... Loosen the screws securing the heat exchanger and pull it out of the frame.
Started this unit. Presumably after three months, the water pressure in the apparatus dropped. Often he will slow it down and stop working. In other words, it absolutely does not hold the pressure. Why is this happening?
If the device does not increase the water pressure, the make-up valve is likely to be leaking. When a shutdown occurs and the water pressure drops sharply to zero, then the 3-way valve is damaged.
Tell me how to clean the cold water filter?
The initial stage is to drain the water from the DHW circuit. Second, unscrew the flow sensor nut. Then we take out the sensor and filter from the cavity. After that we clean from accumulated impurities and dirt.
The device could hum at startup before, but at this time it is much louder. Initially, the sound quickly disappeared, but now it lasts longer. Has anyone observed such a problem?
Excessive noise indicates the presence of mineral deposits inside the heat exchanger, which is heated unevenly due to different wall thicknesses. The more dirty the heat exchanger, the more pronounced the rumble, and, accordingly, the heat transfer decreases.
The unit is functioning, although water does not seem to be circulating in the system. The pump acting on the return flow heats up noticeably. How do I fix this?
Apparently, the mud filter is clogged or the tap is closed somewhere, which interferes with the passage of the coolant. The circulation pump may also be faulty.
What causes the hot water to stop heating? The water comes out very warm. Explain what happened?
Clarification of problems is carried out in the following directions. If the DHW temperature sensor is damaged, it should be replaced. Perhaps there was a failure in the settings for the power of the device for heating DHW.
Flame breakage is periodically visible during ignition. The burner is clean, everything is normal with the chimney, the draft is good. What could be the malfunction?
The unit does not detect a spark due to a weak signal from the combustion mechanism. Here you need to check the wire between the ionization sensor and the electrode. You probably need to tighten it up. There may also be damage to the sensor insulation, which must be replaced.

Each owner of his house tries to make it as cozy and comfortable as possible. To achieve this, you should think about installing a double-circuit wall-mounted gas boiler Ariston, which will help solve problems with heating the living space. The device is very useful in that it will provide heat both in an apartment and in a private house with an area of up to 500 m².
Also, a gas wall-mounted boiler of a double-circuit type Ariston will allow you to quickly heat water for instant use. In this case, a person will not have to connect a boiler, which will require additional investments and a separate place for installation.
Today, on the market for gas boilers, you can find many interesting models... This is quite convenient, since everyone can choose a device that is most suitable for the price, type, characteristics and installation method. Ariston double-circuit wall-mounted boilers gained their popularity due to rare situations with their malfunction, as well as silence during operation, which is very important for maintaining a calm atmosphere in the house.
One of the most important components in all gas boilers is the burner, in this case it can be modulating or conventional. The first option is more popular than the second. When using it, the entire system will be regulated automatically, without human intervention. In this case, the capacity of the installed heating equipment depends on the temperature indicators.
The burner is also divided into 2 types:
The safest is, since it does not imply the ingress of combustion products into the room in case of emergency. Also, in this case, the owner does not have to worry about building a chimney. A special coaxial pipe must be brought to a closed burner, it can always be brought out in any accessible place.
The open-type Ariston boiler, in any case, requires a chimney to bring the combustion products out into the street. Also, don't forget about natural cravings. Air will enter the system from the living area, so it will have to be constantly ventilated.
The coaxial pipe used in a closed combustion system is good because it is made of 2 layers. One is necessary for the removal of combustion products, and the other will ensure the ingress of fresh air into the boiler. Thus, the owner of the equipment does not have to constantly ventilate the room and worry about natural draft. The room will always have enough oxygen.
According to reviews of Ariston gas wall-mounted double-circuit boilers, they have 4 distinctive features useful for their owners:
Recently, the popularity of the Ariston brand has increased significantly due to high-quality gas boilers, and this is not in vain. runs quietly and consumes as little fuel as possible. This will allow the owners of the unit to save on utility bills and, at the same time, provide comfort and warmth to the house.
The client will receive a high-quality device that provides round-the-clock water supply and heating of a house, even with a large area of up to 500 square meters. Also, do not forget about the durability of each boiler. The terms specified in the guarantee are much shorter than they actually turn out to be. In terms of dimensions, the equipment is much more compact than that of other brands, which means that it can be installed absolutely anywhere, even in a small apartment with restrictions on free space.
Almost all gas boilers from the Ariston brand have a capacity of 15 to 30 kW. Thus, each client will be able to select the necessary indicators for the size of his apartment or house. Also worth noting others distinctive characteristics such gas equipment:
In some cases, the boiler cannot simultaneously heat water and provide sufficient heating of the room, this applies to budget models. In this case, a person needs to think about installing an additional boiler.
Note! If we talk about expensive units, they have a special display that shows different characteristics, including the temperature inside the boiler and outside. This is very convenient in terms of entering the necessary characteristics for the correct operation of the equipment.
Before purchasing a gas boiler Ariston, you need to understand that if the buyer does not understand its installation, it is better to contact experienced specialists and entrust all the work to them. After all, even with the most detailed instructions, it is not a fact that the case will end successfully. In this case, there is every chance of damage to the equipment, after which you will have to call repairmen, and this will result in additional costs.
It is very important to keep children away from the equipment. To do this, afterwards, it is necessary to conduct a conversation with them and explain in an accessible language that nothing can be twisted and displayed on the unit, only an adult should do this. If the family leaves, for example, on vacation, after the boiler is turned off, it is also necessary to shut off all pipes for the supply of gas and water. Only then is the equipment disconnected from the network.
If a display is provided on any model, all the indicators that it displays must be strictly controlled. It can display malfunctions or deviations from normal operation that occurred during the heating process.
One of the most important points in the instructions for gas equipment is safety precautions. Before connecting the boiler, you need to familiarize yourself with it first.
All Ariston boilers are divided into 3 series. They have different technical indicators and functions, namely:
The main reasons for the malfunction of the Ariston gas boilers include the following:
When buying one of the Ariston wall-mounted gas boilers from the seller, you must check the availability of all the necessary documentation, which
will confirm that the equipment is in accordance with the manufacturer. Only in this case, problems with the device will arise very soon.
Clas, Clas Evo, Genus models
Ariston clas
Gas wall-hung boilers Ariston Clas: 24 FF, 24 CF, 28 FF / CF, 15 FF / CF, 32 FF
Gas valve SIT 845 SIGMA - Ariston Klass boilers use a gas valve SIT 845 SIGMA with two electromagnets powered by an alternating voltage of 220 V to supply and cut off gas to the burner. A low-voltage (24 V) regulator is used to regulate the gas flow at the valve outlet from the ECU in accordance with the readings of the temperature sensors. This block is used for both natural and liquefied gas... The valve is also equipped with a NAC504 product that supplies voltage to the main burner ignition transformer and valve. The valve is designed to work with different gases without replacement component parts... Only the injector can be replaced. Gas pressure at the valve inlet - no more
6 kPa (60 mbar). Components: gas supply to the burner, supply pressure sensor, maximum power adjustment nut, inlet pressure sensor, inlet connection, ignition device, minimum power adjustment screw, compensator.
Adjusting gas parameters
Checking the inlet pressure:
Loosen the screw and connect the pressure gauge tube to the pressure inlet.
- Set the Ariston Clas 24 FF / CF, 28 FF / CF, 15 FF / CF, 32 FF boiler to the maximum operating power (DHW valve is open). The gas pressure at the inlet to the apparatus must correspond to the passport pressure for the type of gas for which the apparatus is designed.
Checking the maximum power in DHW mode:
To check the maximum power, loosen the screw and connect the pressure gauge tube to the pressure take-off.
- Run the machine at maximum power in Chimney sweep mode (press the Reset button and hold for 5 s.
- The gas pressure at the inlet to the apparatus must correspond to the passport for the type of gas for which the apparatus is designed. If not, remove the protective plug and adjust the pressure with the hex nut.
- After checking, tighten the screw and check for leaks.
- Install the protective plug on the regulator.
Minimum power check:
To check the minimum power, loosen the screw and connect the pressure gauge tube to the pressure take-off.
- Disconnect the air chamber expansion tube.
- Start the Clas System boiler at minimum output and disconnect the cable from the regulator. The gas pressure at the inlet to the apparatus must correspond to the passport for the type of gas for which the apparatus is designed. If not, adjust the pressure with the screw while holding the hex nut stationary.
- After checking, tighten the screw and check for leaks.
- Connect the cable to the regulator.
- Connect the compensator tube.
Power check in soft ignition mode (Performed using parameter 220):
To check the power in soft ignition mode, loosen the screw and connect the pressure gauge tube to the pressure take-off.
- Disconnect the air chamber expansion tube (sealed chamber).
- Open the DHW valve. In the Ariston Klas boiler, the burner is ignited. Disconnect the flame control electrode so that the pressure corresponding to the soft ignition mode is maintained for 8 s without a protective shutdown.
- Change parameter 220.
Adjustment of the heating switch-on delay: Regulation is carried out using parameter 236. The boiler allows adjustment of the delay time from the receipt of the heating command to the burner ignition in the range from zero to 7 minutes. Regulation is carried out using parameter 236.
Adjustment of the maximum heat output: The device has two different maximum power values: in DHW mode and, less, in CO mode (absolute maximum value). The absolute maximum heat output is set by parameter 230. This parameter must be checked and, if necessary, changed only in the event of a change to another gas group. To control the heating output in heating mode, it is possible to adjust the maximum heating output (in the range from the minimum to the absolute maximum value). The boiler allows adjustment of the delay time from the receipt of the heating command to the ignition of the burner in the range from zero to 7 minutes. The regulation is carried out using parameter 236. The regulation is carried out using parameter 231. The device allows you to adjust the maximum value of the heat output.
Main burner - In the Ariston Clas 24 FF / CF, 28 FF / CF, 15 FF / CF, 32 FF boiler models, Polidoro burners with a nozzle pitch of 19.0 mm are used. The electrodes (two ignition electrodes and one for flame presence control) are combined into a block. The gap between the ignition electrodes should be 4 ± 1 mm, the distance between the electrodes and the burner should be 8 ± 1 mm. Distance between flame detector and burner
should be 8 ± 1 mm. If the burner is not ignited after the protective delay time has elapsed, the control panel display shows the code 501. The ionic current must be at least 1 µA. The voltage at the electrode to ground is 110 VAC.
Ignition cycle. In the CO and DHW modes, ignition is carried out in two ways:
DHW - If necessary, three ignition attempts are made: 1st attempt - at the power corresponding to the soft ignition mode; if at the end of the protective delay (8 s) the flame is not detected, the 5P1 signal is generated, the Ariston Class 24 ff boiler makes a second attempt; 2nd attempt - at the power of soft ignition; if no flame is detected at the end of the protective delay (8 s), the 5P2 signal is generated; the device makes the 3rd attempt; 3rd attempt - at the power of soft ignition; if at the end of the protective delay (8 s) no flame is detected, the burner shuts down, signal 501 is generated, the fan is delayed for 40 s, during which the fan runs for
maximum speed, then for another 2 minutes - at minimum speed.
CO - If necessary, three ignition attempts are made: 1st attempt - at 80% power corresponding to the soft ignition mode; if at the end of the protective delay (8 s) no flame is detected, the 5P1 signal is generated, the device makes a second attempt; 2nd attempt - at 90% of the soft ignition power; if no flame is detected at the end of the protective delay (8 s), the 5P2 signal is generated; the device makes the 3rd attempt; 3rd attempt - at the power of soft ignition; if after the end of the protective delay (8 s) no flame is detected, the burner shuts down, signal 501 is generated, the fan is delayed for 40 s, during which the fan operates at maximum frequency
rotation, then for another 2 min - at the minimum frequency.

Ariston clas evo
Modifications of gas boilers Ariston Clas Evo: 24 FF, 24 CF, 28 FF, 15 FF
Boiler hydraulics block
Right hydraulic unit - Modular unit with built-in functional elements: CO and DHW filter. All elements are fastened with clamps. Pump block with deaerator valve. Brass fittings for mounting. Filling tap.
Left hydraulic unit - Modular unit for hot water supply to heating and DHW circuits: safety valve CO 0.3 MPa (3 bar). Automatic bypass. Brass fittings. Everything copper tubes fastened with clamps.
Three-way valve - The three-way valve is used to change the water distribution (to the heating circuit or to the secondary heat exchanger). The valve is controlled from an electronic control unit (ECU) through a relay contact. The valve consists of a composite body and an electric actuator (motor). When the unit is in standby mode, the valve is in the “SANITARY” position. Procedure for switching the 3-way valve. The boiler is in standby mode, the valve is in the “SANITARY” position: When the heating is switched on: the start of the operating cycle in the “Heating” mode is delayed by 7 seconds (the time required to switch the valve by means of an electric actuator from “DHW” to “CO” ). On receipt of a command for DHW: the device immediately starts operating in the “DHW” mode.
Valve in “HEATING” position: When a command is received for DHW: the valve switches from “CO” to “DHW”, while the pump and the burner continue to work. After receiving a command for DHW: if the heating command is not removed, the pump and the burner are switched off for 7 s (the time required to switch the valve using the electric actuator from “DHW” to “CO”. The Clas Evo System boiler starts working again in the “Heating ” d.h.w. only) is set on the control panel The valve has two limit switches (right / left), by means of which the servomotor is switched off when the required position is reached.
Secondary heat exchanger - The secondary heat exchanger of the Ariston Klas Evo 24 ff boiler is attached to the hydraulic unit with two screws. The screw holes are asymmetrically located on the heat exchanger housing, so that it can only be installed in the correct position. Anti-scale temperature setting - To reduce the formation of scale in the secondary heat exchanger. In DHW mode, the burner is switched off and on depending on the readings of the NTC1 and NTCs temperature sensors.
Pump block. Pump type: 24 and 28 kW models. Wilo MTSL 15/5 HE-2; model 32 kW. Wilo MTSL 15 / 6,7-2 CLF12. The ECU allows you to control the switching of the circulation pump from one speed, V2 (55 W), to another, V3 (80 W). In DHW mode, the pump always runs at speed V3 to ensure better heat transfer. In heating mode, the pump can operate at one of two speeds. The value is determined by the temperature difference between the water supply to the heating circuit and the return connection (dT). Procedure: Tp.-arr. T - 2 C is greater than V2; Tp.-arr. T is greater than V3, where T = 20C (the value is set by parameter 239 between 10 and 30 C).
Switching to both lower and higher speeds is carried out with a delay of 5 minutes (unchanged value). Parameter 238 of the boiler Ariston Klas Evo allows you to prohibit switching the pump from one speed to another: 0: fixed. rotation frequency 2; 1: fix. rotation frequency 3; 2: adjustable. The anti-sticking system activates the circulation pump and the 3-way valve for 15 seconds every 21 hours from the moment of the last operation. To control the pump speed, the value of parameter 823 can be used or the voltage (alternating) between pins 5 and 6 of the CN10 connector of the block can be measured. electronic control: 145 V: highest speed; 0 V: lowest speed;
Filling the heating circuit manually - The procedure for filling the CO (empty) circuit is as follows: Open the tap on the cold tap water inlet. Remove the deaerator cap. To open the filling valve, using the magnetic wrench (fixed under the hydraulic unit), set the filling valve to the open position, and the CO circuit starts filling.
Semi-automatic top-up of the heating circuit - The “Semi-automatic top-up” mode should only be used when top-up of the primary circuit is required. Do not use to fill an empty system. On solenoid valve make-up is supplied with an alternating voltage of 230 V (pins 1 and 2 of the CN12 connector of the ECU), resistance 3.7 kOhm. In DHW mode, this mode is inactive. Parameter 248 allows you to disable semi-automatic make-up: 0: disabled; 1: allowed.
If the pressure in the system is less than 0.6 bar, the make-up mode is activated, the icon is shown on the display of the Clas Evo System boiler; in this case, by pressing button 13, the cycle “Filling the system” starts:
The three-way valve switches to the CO position;
- If the pump was turned on, it turns off;
- if the burner was turned on, it turns off;
- after the first filling, the pressure is monitored; if the control result is negative, an error message 1P5 is issued (between B and A);
- pressure constancy is monitored; if the control result is negative, an error message 6P1 is issued (between C and B1);
- to reach the set pressure, a second filling cycle is carried out.
Ariston Clas Evo boiler error codes (when filling)
Error 102 - The pressure sensor is not connected or there is a short circuit in it.
Error 109 - The pressure is above the maximum (3 bar).
Error 111 - The pressure is below the minimum (0.4 bar).
Error 1P4 - The pressure is below the displayed (0.6 bar).
Error 1P5 - The first filling cycle was not completed successfully (the pressure in the boiler did not increase): press the corresponding button and try filling again.
Error 1P6 - Pressure constancy control gave a negative result: press the appropriate button and try filling again.
Error 1P7 - More than 5 filling cycles in 50 minutes, the filling button is blocked (to reset: turn it off and then turn it on again).
Error 1P8 - More than 6 filling cycles in 7 days, the filling button is blocked (for reset: Off-On).
Heating circuit pressure sensor - The proportional pressure sensor measures the pressure in the primary circuit. The measured value is displayed on the display of the boiler Ariston Class Evo 24 ff. The control is carried out by measuring the voltage ( direct current) between pins 8 and 9 of CN04. Correspondence between voltage and pressure values: 0 bar = 0.3 V, 1.5 bar = 2.5 V, 3 bar = 4.8 V. If the computer receives a voltage of 0 V (pressure sensor not connected) or 5 V (input incorrectly connected and output), safety shutdown 102 is performed.
Bypass - The bypass in the boiler is switched automatically, this unit does not need adjustment. In case of pressure loss in the CO circuit due to the operation of the thermostat or zone valves, the bypass ensures a water flow through the main heat exchanger of at least 350 l / h. In addition, the automatic bypass prevents overheating of the heat exchanger, which can occur if the water flow is insufficient. In this case, the boiler temperature is regulated in the usual way, when the temperature setpoint is reached, the burner is switched off. The bypass is located in the delivery unit and is interlocked with a three-way safety valve.
Primary heat exchanger - The primary heat exchanger of the Ariston Clas Evo 24 FF, 24 CF, 28 FF, 15 FF boiler is made of copper with an anticorrosive silicone coating. It is designed to transfer the heat of combustion products to water in the primary circuit. There is an overheating sensor with automatic reset, which operates at 102 ± 4 C. Model - Number of ribs / Dimensions: 24 CF - 82/260 x 180 mm, 28 CF - 89/300 x 180 mm, 24 FF - 91/260 x 180 mm, 28 FF - 91/260 x 180 mm, 32 FF - 105/300 x 180 mm.
Expansion tank- When the water temperature rises, the expansion tank compensates for the increase in its volume. The tank consists of two compartments, separated by a styrene-butadiene rubber membrane. One compartment is filled with nitrogen, the second receives water from the primary circuit. The nitrogen compartment can shrink as the volume of water increases as the temperature rises. The expansion tank is designed for a heating system with a water volume of about 175 liters. Specifications - Capacity - 8 liters. The highest operating temperature is 90 C. The nitrogen pressure is 0.1 MPa (1 bar). The highest working pressure is 3.0 MPa (1 bar).
DHW flow meter - The DHW flow meter has a turbine that rotates the flow of water in the DHW circuit, and a speed meter, the signal from which is sent to the Clas Evo System boiler control unit. There is also a cold water filter to prevent contamination of the flow meter. In addition, there is a water hammer protection device (ECU controlled). For setting, use parameter 252, which allows
set the response time from 0.5 to 20 s (default 0.5 s). The value of the water flow in the DHW circuit is indicated by parameter 825. It can also be displayed on the indicator by pressing the INFO button. For monitoring, you can measure the voltage (DC) at the CN14 connector: 0 V = no flow; 5 V = no flow; 2 to 3 V = flow available. Water analysis available: 100 l / h. There is no water analysis: 80 l / h.
Ariston genus
Gas boilers Ariston Genus are designed to supply heat and are installed in residential buildings and premises. Genus wall-hung boiler models: 24 FF, 35 FF, 24 CF, 30 FF.
Elements of FF models. Sealed combustion chamber - Two-channel flue air intake, Air pressure switch, Condensate drain at the air pressure switch inlet, Heating medium overheating sensor, Primary heat exchanger, Heating water supply temperature (NTC) sensor (NTC 1), Burner and electrodes , Gas valve and
spark ignition generator, DHW temperature sensor (NTCs). Safety valve 0.3 MPa (3 bar), Pump, Water temperature sensor at CO return connection (NTC 2), Infinitely variable fan, Sampler for analysis of combustion products, Gas duct for combustion products, Hall sensor.
Elements of CF models. Open combustion chamber - flue gas pipe, flue gas temperature sensor, coolant overheat sensor, temperature sensor (with negative temperature coefficient) of the water supply to the CO circuit (NTC 1), burner and electrodes, gas valve and electric spark ignition generator, DHW temperature sensor ( NTCs), Safety valve 0.3 MPa (3 bar), Pump, Water temperature sensor (with negative temperature coefficient) on the CO return connection (NTC 2), Primary heat exchanger.
The order of the Ariston Genus boiler in heating mode - The command for heating can come from: room thermostat 1, room thermostat 2, timer programmer, REMOCON remote control and room temperature sensor. The display shows C, then the flow temperature to the CO circuit (measured by the NTC1 sensor). When the unit is in standby mode, the valve is in the “SANITARY” position. When the heating is turned on, the servomotor, which blocked the output of the secondary heat exchanger, is triggered (the shaft extends), the pump inlet is connected to the heating circuit. The circulation device is started with a 7 s delay after the heating command, so that the three-way valve has time to switch; after that, the circulation device directs water from the return connection to the primary heat exchanger.
The fan turns on (models with a sealed chamber). After the pressure switch is triggered, the device can proceed to the next step (in this case, the pressure switch is not re-checked until the next restart). If the relay does not work, after 20 seconds the device performs a safety shutdown 6P1, the fan continues to rotate until confirmation (models with a sealed chamber). After the air pressure switch has tripped, the gas valve and the spark ignition generator are switched on. Gas supply is carried out at the rate of 80% of the ignition power in soft mode; this value can be adjusted using parameter 220. The presence of a flame is monitored by ion current (using a control electrode). The 5P1 error indication indicates the absence of ignition.
The Ariston Genus boiler makes an attempt to ignite in a soft mode (at 90% power). In case of failure, the indicator displays 5P2 malfunction, a third ignition attempt is made at 100% ignition power in soft mode. If the third attempt is unsuccessful, the machine stops. Protective delay 8 s. For monitoring, temperature sensors are used at the supply to the circuit and the return connection. The values of dT flow - arr are used. and the rate of temperature rise at the flow and return choke. The pressure is measured with a pressure transducer. After detecting a flame in the apparatus, the heat output can be regulated in accordance with the required heat output. Regulation can be carried out in the entire range of heat output values - from the maximum (set from the control panel - parameter 231) to the minimum (fixed; set on the gas valve).
The burner shutdown temperature is adjusted as follows:
1st minute after flame detection: T off. = T set. + 8 C
- 2nd minute after flame detection: T off. = T set. + 6 C
- starting from the 3rd minute after flame detection: T off. = T set. + 4 C
This procedure prevents the burner from shutting down too quickly when the temperature setting is reached. It is possible to set the shutter speed before restarting from 0 to 7 minutes (by default 2 minutes, set from the control panel - parameter 236). The pump can operate at one of two speeds. The value is determined by the temperature difference between the water supply to the CO circuit and the return connection. Overheating protection is carried out using a temperature sensor with automatic reset (102 ± 4C) on the supply to the CO circuit (even when the burner is off). When the sensor contacts are opened, the burner is shut down, and after 5 s, if the contacts are still open, the device is locked (which does not allow the operator to restart it), the display shows error 101. From the moment the heating command is received, the “limit temperature” signal (88 C, fixed value) is supplied permanently from the flow temperature sensor to the heating circuit (NTC 1). If the circulation in the CO circuit is disturbed, it is possible to automatically switch to the bypass (throughput no more than 350 l / h).
How the Ariston Genus boiler operates in DHW mode - The water flow in the DHW circuit is measured using a flow meter. The boiler is now in SANITARY mode. The display shows the letter d and the temperature setting. When the unit is in standby mode, the valve is in the “SANITARY” position. If the command for hot water supply is received while the device is operating in CO mode, the three-way valve switches to the SANITARY position. In this case, the circulation pump and the burner continue to work. The outlet of the secondary heat exchanger is connected to the inlet of the pump supplying water to the primary heat exchanger. The pump (speed 3) pumps out water from the secondary outlet and directs it to the primary heat exchanger. The fan turns on at maximum speed (models with a sealed chamber). After the air pressure switch has tripped, you can proceed to the next step.
If the relay does not work, after 20 seconds the device performs a protective shutdown (error 6P1), the fan continues to rotate until confirmation (models with a sealed chamber). In models with an open camera, instead of this, control is carried out from the overheating sensor (it works even during the operation of the device). If the flue gas overheating sensor is triggered, the device stops 601. After the air pressure switch is triggered, the gas valve and the spark ignition generator are turned on. Gas supply is carried out in accordance with the heat output in the soft ignition mode (set from the control panel by parameter 220). The presence of a flame is monitored by
ion current (using a reference electrode). The 5P1 indication indicates the absence of ignition. The Ariston Genus 24 CF / FF, 35 FF, 30 FF boiler attempts to light up in soft mode (at 100% power).
In case of failure, the indicator displays 5P2 malfunction, a third ignition attempt is made at 100% ignition power in soft mode. If the third attempt is unsuccessful, the device stops with error 501. Protective delay 8 s. To control the water flow, temperature sensors are used at the supply to the circuit and the return connection. The flow T values are used. and the rate of temperature rise at the flow and return choke. The pressure is measured with a pressure transducer. The burner flame can be regulated in the entire range of heat output values - from the maximum (installed on the gas valve) to the minimum (also installed on the gas valve). The burner runs until the descaling temperature setting is reached. This temperature is measured by the NTCs sensor in the DHW circuit. Overheating protection is carried out by a temperature sensor with automatic reset (102 ± 4 C) on the supply to the heating circuit (even with the burner off). When the sensor contacts are opened, the burner is shut down, and after 5 s, if the contacts are still open, the device is locked (which does not allow the operator to restart it), the display shows error 101.
Working Modes
Chimney Sweep Mode - This mode is used for proper flue gas analysis and calibration to maximum and minimum values. Press the Reset button for 5 seconds. If the boiler is in the “Winter” mode, the three-way valve is in the “CO” position, and the burner turns on even without a heating command. The device is in the "Summer" mode: in the absence of a command for DHW, the device operates in the CO mode; if there is a command for DHW, the device operates in DHW mode. In the "Chimney sweep" mode, the temperature measurement (by the NTC 1 sensor) is carried out as follows: "Summer" mode more than Off: 86 C; On: 81 C; Winter mode over Off: 89 C; On: 84 C. To exit Chimney Sweep mode, press the RESET button. If this is not done, the device automatically exits this mode after 10 minutes.
Comfort mode - In this mode, the Ariston Genus 24 FF, 35 FF, 24 CF, 30 FF boiler starts to supply hot water to the DHW circuit faster. For this purpose, in the primary circuit of the boiler, heat... Press the “C” (comfort) button. In Comfort mode, the display shows the COMFORT icon and the letter C, as well as the temperature measured by the NTC1 sensor. The device switches to Comfort mode at each command for DHW and maintains it for 30 minutes. To exit this mode, press the “C” button again. Menu parameter 2 50 allows you to set the Comfort mode as follows: 0: disabled; 1: switched on within 30 minutes after the command for DHW; 2: always on.
Frost protection mode - The mode is effective only when the ON / OFF switch is in the ON position. The transition to this mode is carried out according to the readings of the temperature sensor on the supply to the CO circuit (NTC1). Temperature measured by NTC1 probe: 3 to 8 C - The pump is running at speed III. The three-way valve switches alternately for 1 min to the "CO" mode, for 1 min - to the "DHW" mode. The display shows the letter F and the temperature value measured by the NTC1 sensor. Operating time: until the temperature measured by the NTC1 sensor reaches 9 C. The temperature measured by the NTC 1 sensor: below 3 C - The burner turns on at minimum output; The pump runs at speed III. The three-way valve is in the "CO" position. The display of the Ariston Genus boiler alternates between the letter F, the number 2 and the temperature value measured by the NTC1 sensor. Action time: until the temperature measured by the NTC 1 sensor reaches 30 C.
If the temperature sensor on the supply to the CO circuit NTC 1 does not work (open or a short circuit has occurred), the transition to the "Frost protection" mode is carried out according to the readings of the NTC 2 sensor on the return connection, but in this case only the pump works (the burner does not turn on) ... The display does not show the frost protection mode, but the error code 110 of the NTC 1 sensor for a short circuit or an open circuit. The device enters frost protection mode even if the NTC 2 sensor is not active (open or short-circuited), but in this case only the pump is running (the burner does not start). The display does not show the frost protection mode, but the error code 112 of the NTC 2 sensor - short circuit or open circuit. The appliance enters frost protection mode, even if there was a shutdown due to non-flame detection, error code 501, or blocking due to overheating, error code 101, but in this case only the pump is running (the burner does not start), and the display it is not the frost protection mode that is displayed, but the lockout error code. In case of disconnection
power supply, all settings are saved in the device, and after the power is restored, it switches to the mode in which it worked before it was turned off.
Ariston Genus boilers flue gas removal system
On the outside of the apparatus there is a flue gas collector with two samplers to determine the temperature of the flue gas and air inlet, the content of O2, CO2, etc.
Air pressure switch - A pressure switch is provided in the unit to control the proper discharge of combustion products. 25 kW: Open = 50 Pa (0.50 mbar); Closed = 60 Pa (0.60 mbar); 30 kW: Open = 74 Pa (0.74 mbar); Closed = 89 Pa (0.89 mbar); 32 kW: Open = 74 Pa (0.74 mbar); Closed = 89 Pa (0.89 mbar); The first pressure value is taken at the fan outlet (connection “L” of the pressure switch). The second pressure value is taken in the combustion chamber (pressure switch “H” port). Both values are negative (below atmospheric), but the pressure switch monitors the difference between the indicated values (to measure this difference, you can connect a differential pressure gauge to the pressure taps located at the top of the device). When the Ariston Genus boiler is operating, the pressure switch contacts are closed. The device reacts to opening the contacts. 607: The pressure switch contacts are closed before the start of the ignition sequence. 6P1: The pressure switch contacts are not closed, although the fan has turned on.
Variable speed fan - The following fans are used: 24 kW: with 35 W motor; 28 kW: with 45 W motor; 32 kW: with 60 W motor; A Hall sensor is used to measure the fan speed. Upon receipt of a command for heating, the ECU starts the fan at maximum speed (up to 2800 min – 1). After the pressure switch has tripped, the fan switches to the ignition speed (different for DHW modes and CO), which allows you to optimize the ignition of the burner. After the presence of a flame has been detected with the help of the control electrode, the fan speed can be controlled in accordance with the required heat output.
The fan speed is adjusted in accordance with the gas supply through the gas valve in the direction of increasing or decreasing, respectively, more or less current is supplied to its winding. For monitoring the speed on front side the fan is equipped with a Hall sensor. If, within 10 seconds, the fan speed drops by more than 100 min – 1 below the minimum (1750 min – 1) or if a broken connection with the Hall sensor is detected, error 604 is output: fan off delay: 40 seconds at maximum speed ; 2 minutes - at the minimum. To monitor the fan speed in min – 1, use parameter 8-22 or measure the signal frequency between pins 4 and 5 of CN07. Parameter 222 allows you to prohibit switching the pump from one speed to another: 0: adjustable; 1: fixed.
Ventilation shutdown delay - The fan operates with shutdown delay: 40 s at a frequency of 1900 min – 1 (after shutdowns 501 and 103); 20 s at maximum speed (after stops due to lack of water circulation: 103, 104, 105, 106 and 107), 10 s at 1900 min – 1 (after stops due to lack of water circulation: 1P1, 1P2 and 1P3); 5 s for 1900 min – 1 (after each burner shutdown).
Fan off delay after a heating command: parameter 243 = 0: 5 s for 1900 min – 1 (every time after the burner is switched off); parameter 243 = 1: 3 min for 1900 min – 1 (whenever the burner is switched off).
Fan off delay after DHW command: parameter 254 = 0: Tp. less than 75 C = turns off without delay; Tpod. more than 75 C = 3 min (minimum speed); parameter 254 = 1: 3 min (constant time, minimum speed).
Flue gas monitoring (Ariston Genus 24 CF boilers, open combustion chamber) - An overheating sensor with automatic reset, installed in the flue gas duct, sends a signal to the ECU, which ensures proper monitoring, provided that the ECU is powered. When the overheating sensor is triggered, the device is turned off, the indicator displays error code 601. Reason for triggering: The temperature in the flue gas outlet has exceeded the sensor trigger setting, 75 ± 3 C. After 12 minutes, the sensor is automatically reset, since the temperature during this time has time to drop ... To immediately reset the sensor, you can turn off and then turn on the power to the ECU. Error messages when the overheating sensor is triggered - 601: the overheating sensor has triggered (safety shutdown). 601: open circuit of the overheating sensor (safety shutdown).
Flue gas evacuation system (sealed chamber, FF models) - The device allows installation of both coaxial (60/100 mm) and two-channel (80/80 mm) flue ducts (respectively, two connection options). Flue gas samplers are built into the throat of the flue gas manifold.

Gas boilers are manufactured by different companies, which is accompanied by the supply of equipment to the market that requires an individual approach to installation and operation. But I don't want to overpay for calling a specialist for installation work, right? But how to connect the Ariston gas boiler yourself, taking into account the individual characteristics of the purchased equipment?
We will try to help you deal with this task - our publication describes the procedure for installing, connecting and configuring a gas boiler. The sequence of work when performing the first start-up of the equipment is also given. The stated material is supplemented vivid photos and a video.
Wall mounted boilers are, perhaps, the most common among household gas equipment - they are most often potential buyers.
So, a modern gas wall-mounted boiler of the Ariston Net model allows you to: start, stop and control the temperature background of heating and hot water supply. Moreover, all these actions can be performed from anywhere at any time by using a familiar smartphone or personal computer.
Potential buyers of the XXI century prefer to install such intelligent gas equipment using the example of the Ariston Net household boiler.
The system provides constant control of energy consumption, which is accompanied by significant gas savings. Thanks to the special software, the owner of the equipment receives real-time notifications of malfunctions.
In addition, if you activate remote control, it becomes possible to solve most problems remotely. However, let's first look at how to properly install a gas boiler for household use of the Ariston brand, as well as the features of its connection, settings and procedure for the first start.
Judging by the requirements of the manufacturer of boilers Ariston, the installation of equipment is the prerogative of exclusively specialists.
Hence the corresponding conclusion - self-installation and the first switching on of the Ariston household gas boiler is theoretically impossible (more precisely, unacceptable). Moreover, the first start-up of equipment is prohibited without a representative of the gas service.
The manufacturer also reminds the future user regarding the quality of the water with which the gas wall-mounted boiler will work. It is noted: if the water quality ( chemical composition) does not match technical requirements, the performance of gas equipment is not guaranteed by the manufacturer during the established warranty period.
Installation of gas equipment according to the "B" scheme requires the organization of efficient ventilation and air intake in the working rooms.
Premises where corrosive vapors may appear in the air, it is allowed to use only the installation according to the "C" scheme (outside air inflow). Such requirements provide corrosion protection for Ariston gas boilers.
Kits for connecting a chimney / air duct, as a rule, are not included in the list of equipment of the Ariston gas boiler. Accordingly, additional kits are ordered for a specific connection.
This is how the "pipe in pipe" system looks like, which is used as part of the construction of Ariston gas boilers of some models
Many gas boilers of the Ariston brand are made taking into account the supply of air and the removal of gases through a coaxial system, the pipe diameters of which are 60 and 100 mm. Alternatively, a separate version with pipes for diameters of 80 to 80 mm can be used. The selection of the configuration of the gas outlet and the air duct is accompanied by taking into account the additional aerodynamic resistance.
To fully ensure safety, the manufacturer requires the involvement of a qualified specialist to connect and check all electrical connections of the Ariston gas boiler. The manufacturer removes the warranty for the equipment if a poor-quality power supply network is used and.
The grounding circuit for a gas boiler installed inside a private house is a mandatory measure required not only for Ariston boilers, but also for any other similar equipment
The power supply system is designed for the maximum power consumption parameter of the gas boiler. To connect the equipment, electrical conductors with a cross section of at least 0.75 mm 2 are used. Correct safe work gas boiler provides reliable grounding.
The power supply parameters must be brought in accordance with the norms of the 230V / 50 Hz network, observing the polarity and the presence of a grounding conductor. The grounding conductor must be used with a greater length in relation to the phase conductor and neutral. Wired connection - strictly permanent, without the use of sockets and plugs, made through.
When with installation work and the connection is over, you can proceed to setting up and testing the equipment.
The initial action accompanying the first start-up of an Ariston brand gas boiler is water. In this case, it is necessary to install air valves radiators in a working (open) state.
The same actions aimed at bleeding air from the system apply to circulation pump boiler. As the circuit is filled with water, air is removed from the system, the water pressure on the manometer reaches 1 - 1.5 atmospheres, the tap on the make-up line is closed.
The first start-up of a gas boiler is usually accompanied by preparatory operations related to filling the system with water, bleeding air, checking the tightness of gas lines
At the next stage of commissioning of a gas boiler, actions related to the gas supply are performed.
The procedure is approximately as follows:
Testing the regulator unit and burner for tightness is carried out by short-term opening (no more than 10 minutes) of the main shut-off valve of the gas line. In this case, the solenoid valve and the manual boiler shutter are set to the closed position. In this position of the system, the gas flow meter should show a zero result (no leakage).
Modern gas heating equipment is equipped with a control panel where the user can set the desired parameters of the unit. Next, let's take a closer look at how to set up a household gas boiler of the Ariston brand.
Control during the operation of the boiler, as well as control in the mode of the first start-up with the necessary settings, is carried out through the user control panel Ariston
Actually, the user's actions on the control panel are obvious here:
Next, the gas parameters are checked, for which the front panel of the boiler is dismantled, the control panel plate is lowered and test manipulations are performed with the connection of the measuring manometer to the pressure take-off pipes.
These operations are the prerogative of gas service specialists.... Self-execution is not recommended, since it is necessary to clearly know the functionality of the equipment.
Ariston control panel keyboard layout: 1 - information screen; 2 - regulation of the DHW temperature; 3 - mode selection key (Mode); 4 - "Comfort" function; 5 - ON / OFF key; 6 - "Auto" mode; 7 - reset key "Reset"; 8 - regulation of the temperature of the heating circuit
Then the boiler starts up in test mode through the system function "Chimney sweep". To enter the test mode, activate the reset button and hold it down for at least 5 seconds. Exit the test mode by re-activating the reset key.
This type of test also provides for a control selection of pressure at specialized points of the equipment, followed by measurement of parameters on a pressure gauge. It is necessary to disconnect the compensation pipe of the combustion chamber. Again, the "Chimney sweep" mode is applied, activated through the control panel.
The boiler is tested for the minimum power level in the same way. True, the modulator adjusting screw is additionally used if it is necessary to correct the value of the minimum operating pressure of the boiler. On this occasion, a video is posted below, where the modulator is for some reason called a motor.
The device startup process involves the following user actions:
If all actions were performed by the wizard specialized firm, then he checks the compliance of the gas pressure during the operation of the unit and draws up a corresponding act.
Wall-mounted gas boilers from a series of modern equipment of the Ariston brand are a rather complicated technique, even for domestic purposes. Hence the logical conclusion on the installation and start-up of the Ariston gas boiler - the initial start-up of the system should be entrusted to specialists. The costs are, of course, inevitable, but on the other hand, this is how it is guaranteed correct work gas system.
