Heating boiler Oasis ZRT 24. When the hot water is turned on, hot water goes not only in the crane, but also warm the batteries, and the pump is slightly noise. All this is on the summer mode.
Most likely, the problem is in the work of the three-way valve and servo. Check if the servo rod is triggered by the end when the hot water crane is opened. Boiler malfunction or rod zaking is possible.
Model ZRT-18. Water flows from pressure valve. Who has any thoughts or who did what to eliminate the flow. In operating 6 years.
Unscrew and check the flowing valve and replace it as necessary.
Wall-mounted gas boiler Oasis 18 runs on all power, does not turn off. On the scoreboard indicator shows an open crane icon, so the gas supply is not turned off, except in manual.
Perhaps the duct sensor was blocked, or the rod of the rod in the three-way valve. Check the duct sensor and rod.
OASIS ZRT 24. During the ignition, the problem (DHW mode or heating is no difference): it turns on, it turns off with a crackle relay, even when the flame appears, and only after a few seconds, the burning is already burning smoothly, without failures. Sometimes from the first attempt is not burned, but in a mistake I have never left. The thought is to work out the health of the flame control sensor, the maintenance of the pressostat.
It is necessary to check the flame ionization sensor, as well as clean the ignition electrodes and the burner nozzle.
Wall-mounted gas boiler OASIS 24 kW with connected external thermostat. The problem is this: when there is a temperature thermostat, say 30 degrees, the unit begins to work, while almost continuously pumps and the pressure is constantly growing, to the mark 3 and higher, when the room temperature reaches the specified value, the pressure in it drops to 0 and pops up E9 error. I raise the pressure (I type water into the system), starts to drip somewhere from below, at a thermostat I exhibit a large temperature - the problem is repeated further. Tell me, what could be the cause of a malfunction?
In the expansion tank. He or blown away or burst. The problem may occur due to the faulty membrane in the expansion tank. Check out its condition, making sure that the tank does not appear on the nipple of the tank. The pressure in the expansion tank should be 1 bar.
I have a two-circuit boiler Oasis ZRT 18 and that's what is the problem with him. The display constantly burns with a water turned on, it will be heated until you turn off it.
Most likely, the GVS duct sensor is constantly rotating, it could be closed. Try turning off the sensor and check whether the crane has extinguished on the display. If it goes out, then the sensor is not working, if not, then the problem is in the control board.
After five years of normal operation, the boiler began to issue an E2 error. At first, when the start there were clips of the relay, but the error did not go out. Then the relay click and during the operation of the unit, and it is Tuh. Now the error comes out when started, then during operation. I think on the press service, because I turned the adjusting screw on it to the side of Plus on one turn, and the device did not give an error, although the relay clicked remained both when started and during operation, but it was reduced. What else could be the cause? Venturi's tube shot, she is clean, the fan is the same, the blades are clean. I checked the ignition electrodes, all connections and pads, filmed the control board for unpains, fastening the sensors. I found that the electric drive of the three-way valve hangs (the rod goes). I corrected the reversal of the lock plate, but it did not affect the boiler. It also works with the relay clicks, but the second day has not yet stopped. According to my thoughts, everything converges to the press.
Check the press space tubes for condensate and delete it as needed. If there is no condensate or remove it does not help, then replace the press service and install the condensate.
Problem in the circulation pump ERKO DWP 15-50 A. Soared pump snail, plastic. How to remove the pump?
Replacing the pump. To dismantle circulation pump, It is necessary to remove the front panel of the unit, unscrew the pump from the bottom of the pump and remove the two clips on the entrance and pump output tubes.
Gas wall boiler Oasis 24 kW. In the house (120 squares) warm floors. The floors warm up long, but then they keep warm long. The circulation pump is turned on every 5 minutes, and there is no point in it, since the burner is turned on no more often than two times per hour. Tell me, please, is it possible to change the pump switching interval? By the way, the boiler was pleased, translated it to propane, works well, in the frost consumption of approximately 2 cylinders for 6 days. The only one had to put an additional expansion tank, since when heated, the pressure was unacceptably rising and had to be discharged to the norm, but even after not a significant cooling of the coolant, the pressure fell below the norm, and he worked poorly. Cylinders put 2 pieces low pressure parallel. Cylinders ceased to freeze, and now burn completely.
Check the service settings - they must correspond to the values \u200b\u200bof a system of warm floors and liquefied gas. The pump is working correctly, seeking a turn of the coolant of uniform heat transfer. There is no need to change the pump for switching on the pump, there is only the ability to put it on the mode of constant work.
Oasis VM-24 oasis boiler, double-circuit. There was such a malfunction. When the pump is executed periodically, the turbine turns on with it and approximately 30 runs 30, then it turns off, and the pump continues to heat the water. Rosge does not happen, because the water in the system has not yet cooled to a given one. With a circulation pump, everything is clear why the turbine is turned on. This happens not often, but still I noticed.
Independent inclusion of the turbine does not bear any negative impact on the operation of the unit. This can occur when the contour of the hot water supply is turned on, which is the norm, or due to the fact that an unauthorized signal on the inclusion comes to the launch capacitor of the turbine. This can occur due to wandering currents, the presence of which can be properly distributed by measuring the currents of the gas pipe. If there are currents, you need to install a dielectric coupling.
Gas double-circuit boiler OASIS BM-16. Connected to heating and water. Heating is normally working, and when the hot water is turned on, the indicator does not light up. Such a case was in the fall, but within 2-3 days he was repaired. In the beginning of the spring, problems began, the water began to warm the water, in the end, it does not turn on at all. Tell me, please, in detail, can I manage or search for yourself or wizard?
If the boiler does not work the DHW contour, then the probable cause is a duct sensor, which is installed in the cold water input nozzle in the DHW circuit. It is a turbine that could touch or score, thereby ceasing to apply the signal that water flows in the nozzle. You can independently check the condition of the sensor, breaking the water, unscrewing the supply of cold water from the unit of the aggregate. Make sure the sensor is not flared and is able to move freely rotate.
Who met such a BM-16 boiler malfunction? Heats up to a given temperature water in heating system The displayed, turns off, turns to circulation, the temperature is reset, but it does not turn on.
In your case, it is necessary to figure out the fault in more detail. Depending on the model, certain actions are possible.
Tell me what to do, I tadil the automatic air cut into the heating system, after that I began to start the boiler. Oh turns on, burning out, then the pump begins to lie down, the E9 error display and stops working. I can not find the cause.
ERROR E9 signals insufficient pressure in the heating system. On the pressure gauge when the boiler is turned off, the pressure must be at least 0.8 bar. If it is lower, then add water to the system using a fuse crane. It is also possible to have air in the circulating pump - to lower the air, weakening the plug in the center of the front of the pump.
Installed wall mounted boiler OASIS NZR-13. The problem is as follows: put the heating temperature to a maximum of 80 degrees. The output tube of heating is very hot, the batteries are slightly warm. Invited a specialist from the service center. He looked and says that a lot of gas is served, the unit quickly gains a temperature and turns off, and the water in the system does not have time (the pump in the third speed). Now it is trying to reduce gas pressure, and something does not work. Maybe tell me where and how is it done?
Most likely, scale was formed in the heat exchanger, which leads to boiling water. The second reason is the wear of the pump, the weak rotation of the impeller, or just dirt. Check and cleaning the heat exchanger and pump.
Heating boiler ZRT 24 kW. It works fine at the first startup, but with a characteristic noise, as if the air is in the system or how boils. Subsequent warming up with the same noise, but the temperature quickly rises, and it swings. DHW is working fine. Explain what reason can be?
Most likely, the reason in the pump is jammed the impeller. Unscrew the plug and try checking the impeller manually. Another reason may be scale in the heat exchanger.
Malfunction of the Oasis MTT-24 Oasis. The heating system works normally at any given temperature, but the DHW operates only when the temperature is displayed in the range from 30 to 37 degrees. If you put more than 37, then it works about 1-2 minutes, and then emergency turns off the burner without any errors, but with a slight crack. Then after half a minute, it turns on and so in a circle. If during the emergency shutdown, close the crane with water, the unit switches to heating and shows the temperature of 90 degrees. Then the pump is turned on, and everything starts to work normally. The unit is almost 5 years old, the service has never done, water from the water pipeline, the filters are not worth it. The head from the crane is excellent.
Most likely, in the secondary heat exchanger, it is necessary to make it clean. The boiler is turned off, since the overheating sensor works.
Copper wall-mounted dual-circuit oasis VM-24 kW. I bought a house, stood this unit, soon cold, and the heating is terrible. It turns off once, turns off, 2 hot batteries, and other warm. Then turns on only 4-5 hours, and the batteries are cooled quickly. On the street +10, and we are already freezing. Thought the thermostat broke, disconnected the wires, then joined each other, and he did not turn on. Why dont know. The idea was to immediately turn on and warm. And now there is still a strange opposing squeak. How to fix everything tell me, please?
A characteristic snoring sound can be from an expansion tank (lifting air from the spool), or the circulation pump that must be checked, to strip air through the central plug.
Oasis Gas Wall Mural Error Codes
Error E1. - No gas - open a gas crane. Gas valve is faulty - replace gas valve. Electrodes do not see the flame - clean or replace ionization electrodes. The control board is disabled or faulty - check the quality of connecting all wires. Replace the fee if necessary. If the replacement does not help, the diagnostics is incorrect.
Error E2. - No thrust in chimney (zoom) - check the chimney. Venturi tube is faulty or clogged - clean or replace the Venturi tube. Condensate traction accumulated in silicone tubes - check the tubes and the quality of their connection. The thrust sensor (air pressostat) is faulty - check the performance of the sensor, if necessary, replace. The turbine does not work - check the operability of the turbine and, if necessary, replace.
Error E3. - overheating of the heat exchanger - check whether the taps are open at the entrance and outlet of the heating circuit. Fault of the overheating sensor - replace the sensor. In the working condition, the sensor is closed. Blurring at 92c.
Error E4. - worked the coolant overheating sensor (94c) - check the reason high temperatures. No coolant overheating sensor - if the boiler has not renewed when cooled, replace the sensor.

Reset overpressure automatic valve. In this case, from silicone tube Water will go. The water pressure sensor is defective - if the pressure gauge shows that the pressure is, then you need to replace the water pressure sensor.
Error E0. - In the DHW circuit or heating, a temperature of less than 1C is fixed - to carry out work on errors E5, 6 and 7. Control the temperature in the boiler.
Oasis boiler. Already twice there was something unclear. It is on for heating with a temperature of 55 degrees, everything seems to work. But suddenly I look at the scoreboard, the figure of 07 appeared, and the unit works without stopping and the battery can not be hurt - hot. I became the off buttons - does not react. Only turning off the outlet. What kind of failures have become? Maybe broke at all? Included in the outlet - it works fine again. I'm afraid to leave it unattended. Suddenly there will be a failure. What about him?
Most likely, the problem with the control board and its replacement is required.
In the boiler VM-16, water boats at the input of the DHW, the duct sensor burned out, from the alignment of the Americans to flow with steam. Gasoviki said such a feature of these models.
The reason for such a malfunction, overheating and failure sensor GVS. A heat exchanger could become, who clogged and failed.
Bought a gas boiler Oasis BM-24. I want to translate it to a balloon (liquefied) gas. What pressure must be installed? And what other settings need to be changed in service menu? Nozzles already bought. And another question - with the help of a pressure gauge, you need to change pressure or not?
To translate the boiler to work with liquefied gas, It is necessary to replace the nozzles and change the parameter Fa in the service menu, replacing 0 to 1. Yes, the gas pressure on the burner must be about 80 mm (maximum) and 30 mm (minimum). Pressure is measured on the gas valve fitting.
Model NZR-24. Problem in self-shutdown. That is, without errors and without visible reasons, the unit spontaneously turns off, on the off display. Come on, press the power button, and it works further for a while. Then it turns off again. Intervals are always different. Maybe every hour turns off, and it can work normally for a week. It is noticed that it turns off during the ignition, that is, it is trying to regret, it does not work with something and it turns off. Iskra like normal, gas comes. The network is connected via a uninterruptible (but I tried it without it - the same thing).
On the gas pipesuitable for the boiler, is there a dielectric coupling? If there are no couplings, we advise you to put it, and if there is a unit so works, it is possible that the problem is in the control board and it is necessary to replace it.
I have a gas boiler Oasis VM-20. The house is new, connected everything except gas. I decided to fill the system. Unscrew the plug on the pump, opened the heating cranes, opened cold water. And unscrewed the fuel faucet, but water does not flow into the battery system. How do I fill the heating system with water?
Most likely, the problem is associated with an incorrectly mounted heating system, or incorrect installation of the boiler. Check the heating system and all connections or call the wizard.
Tell me, please, we want to install a wall-mounted boiler in the apartment and fluctuate between Oasis BM-16 and RT-16. The first with a separate heat exchanger, and the second with the bittermic. The remaining parameters are the same. What is the difference? What is better to take? Apartment 2/2. brick house, 68 square meters. m.
The first model BM-16 has a bitmary heat exchanger, and RT-16 are two separate heat exchanger. In boilers with a bietermic heat exchanger, there is no separate secondary heat exchanger that is only responsible for the outline of the DHW, which makes them cheaper, but the heat exchanger of such models is more sensitive to the quality of water and if water tough, with a high salt content or well, the Bi-Letter Aggregate clogs faster. In such cases, we advise you to use the RT models with two separate heat exchangers.
Tell me who knows. I can not force the ZRT-18 boiler to work with external control, that is, I put a jumper on the terminals, I remove it, and it still works on the internal temperature settings.
Initially, a jumper is present between the terminals for connecting the room temperature sensor. You must first remove this jumper (snack it) and then connect the room temperature sensor.
Tell me, please, why on the boiler Oasis VM-18 hot water That boiling water, then cold? The settings do not help, the amount of water also changed.
Check the settings in the service menu, the gas pressure comes to the burner must be exhibited MAX-12 MBAR, Min-2 mbar, also a heat exchanger could also score.
I have a boiler NZR-13. I exhibit the heating temperature of 58 degrees. It heats up 3 degrees above and turns off, then turns on at a temperature of 45 grams., I.e. it cools at 13 degrees., And according to the passport, it should cool 7 degrees. So should be? And another problem: pressure in the heating system at 58 degrees. 2.5 bar, and when cooled to 45 degrees drops to 1 bar. This is normal? If, when blending, set the temperature less, you have to add water into the system, since when cooled pressure drops below the red line on the pressure gauge and the boiler gives an E9 error. And if you still turn off the electricity even for 40 minutes, then the pressure drops almost to 0. If you add a temperature when cooling it, then you have to drop pressure in the heating system, since it reaches the upper red feature on the pressure gauge. In short, the temperature was reduced - the pressure added, added the temperature - dropped the pressure. It should be so?
The factory settings such that the unit heats the coolant to a temperature that is more exhibited by several degrees, turns off the burner and turns on the heating when the difference between the actual and temperature will reach 15 degrees. In the system settings, you can change the specified difference by making it either 10 or 7 degrees. For this corresponds to the "HC" parameter (value 00 - 15C, 01 - 10C and 02 - 7C). The pressure jumps you have described may be a consequence. insufficient pressure In the expansion tank, which in the missing pressure in the system should be 1 atm. It is also possible that the membrane burst into the expansion tank and its replacement is necessary. You can check this by clicking on the nipple of the tank, if water goes out of it, the membrane failed.
Wall-mounted gas boiler Oasis NZR 16 cuts off gas burner. At the fraction of a second when submitting a DHW or heating. No errors are not displayed and continues to work. What is the reason?
A short-term shutdown of the burner is possible for several reasons, for example, due to the gas valve. More precisely, it is possible to find out the reason only in place. Such work is not a malfunction and does not affect its efficiency and efficiency.
The problem is as follows - hot water is heated unstable. When the crane is opened, the DHW icon on the display (shower) stopped. And the water is heated only during the ignition of the gas. And I can not understand the logic of it. Water can go hot, then it is cold again, and then start to warm up again.
The reason for the work of the boiler is most likely a water flow sensor in the DHW circuit. Its part that is located inside the pipe of the input of the cold water in the DHW, is an impeller, which could cling, or take the wrong position, which became worse to scroll and not give a proper signal to the Hall sensor on the control board, in connection with which the unstable occurs Work of the aggregate. It is necessary to clean the flow sensor and, if the cleaning does not help, replace it with a new one.
I have a ZRT 18 boiler, a circulation pump broke. I did not find the same, but I bought and put Grundfos. The unit began to issue an E9 error that in the summer mode, which is in winter mode. I do not know how to fix it. In the summer mode, the water includes, it turns on, but after closing the crane, an error pops up. And in winter mode after warming, when the pump stops to drive, it appears, and in connection with this, the boiler does not turn on the pump and does not want to run while you can not pull out of the socket.
E9 error appears, or due to low pressure in the heating system and it is necessary with the help of a feeding crane to bring pressure up to 1 atm., Or due to the failure of the pressure sensor, which will need to be replaced with a new one. If the heat exchanger is dried, then it is better to take it to his master to determine the place of leakage and clarify whether it is possible to pan or need only replacement.
In the summer mode, when the hot water is turned on, the heating batteries begin to heat up, the temperature of the hot water in the tap in sensations is significantly higher than the exhibited. Tell me, what could be the reason?
Most likely, the circulation pump is not turned off. It is necessary in the service settings to set the cl per 00 parameter.
Does you have a gas boiler "Oasis"? Then you will be useful to get acquainted with typical faults This technique. During operation, the instrument nodes may fail. We will tell you how to recognize the problem and eliminate it with your own hands.
The devices of this manufacturer are dual circuit. This means that the water heater can produce not only hot water in the crane, but also the heating indoors. The temperature of heating is from 35 to 60 degrees, the average capacity is 10 liters per minute.
Technique "Oasis" works on natural gas, so it can be installed in the houses to which the highway is supplied.
The boiler is equipped with two heat exchangers. One of them is responsible for providing water of batteries for heating, the other for hot water supply (DHW). Accordingly, fuel consumption and heating time in summer period Reduced.
Combustion products are discharged forced. Closed camera and provide automatic and safe operation. For control, flame sensors are installed, gas supply, duct. Also provided a safety valve, which is triggered by improving pressure.
Does not do without troubleshooting. The technique is equipped with a self-diagnosis system. In the event of a failure in the display, an error is displayed, the value of which is indicated in the instructions.
What should I do if an error was highlighted on the scoreboard? How to fix the situation? First you need to decrypt the symbol value on the screen, and after that it starts to search for breakage.
Consider what symbols that show the boiler are.
E1 - Ignition problems, no ignition. What could have served:
E2. - The fan has been worked for 8 seconds, but the pressure relay does not closes. What does it mean:
In this case, you need to clean the chimney for its part, and for cleaning from the street, cause public utilities. Open the combustion chamber. You will see that two tubes that also need to be cleaned are connected to the panosatat (pressure regulator);
E3 - The input DHW temperature sensor was output. Specify the sensor and wiring diagnostics. Replace faulty parts.
E4 - broken output sensor DHW. Act the same as in the case of E3.
E5 - Heating sensor does not work. Similar actions.
E6. - There is no flame. What to do:
E7. - Low pressure in the highway. What could cause the problem:
E8 - Water overheats. What is the reason:
E9 - The pressure in the system does not correspond to the norm. The pump is broken, so the burner may not be lit.
We looked at all errors characteristic of oasis gas boilers. In addition, users faced such a malfunction as no heating: when the mixer is opening there is no hot flux. This indicates a breakdown of the turbine. It is impossible to repair it, it is better to install a new one.
Before starting work with the technique, overlap the supply of gas and water. If the error code does not disappear from the screen after all the efforts made, contact a specialist. Do not hold independent work With the gas mainstream - it is dangerous and can lead to an accident.
The oasis mounted boiler seems to work, although there is no water circulation in the system. The return pump is noticeably heated. What is the reason?
The filter-mud or somewhere blocked the faucet, which prevents the passage of the coolant. Could also fail circulation pump.
I would like to know what purpose the protective thermal sensor is installed in the system?
This component suspends the gas supply for the burner, when overheating the fluid of the primary heat exchanger.
Installed a week ago the oasis boiler. Now, at the time of start, the wick burns five seconds, but the main burner does not support the fire, and because of this, the device begins to go out. How can this problem be solved?
Judging by the description, it has a defect of the ignition unit or a problem in the burner. Just in case, check if the phasing is not disturbed at the time of connection to electricity.
The heat exchanger is freely removed from the boiler when using a simple screwdriver. Below the description of the dismantling procedure. Drain the water from the device using the exhaust crane. Then it is necessary to empty the DHW system. Unscrew the fastening screws of the heat exchanger and remove it from the frame.
Fulfilled the connection in early August this device. Allegedly after 4 months, the contour of the DHW stopped working, although heating mode functions as it should be. I tried to turn on the hot water, but the unit only depicts the temperature, and the heating is not going to produce. Help how to fix?
Most likely, the problem is in the 3-sided valve. It requires replacement.
Gas double-circuit boiler OASIS BM-16. Connected to heating and water. Heating is normally working, and when the hot water is turned on, the indicator does not light up. Such a case was in the fall, but within 2-3 days he was repaired. In the beginning of the spring, problems began, the water began to warm the water, in the end, it does not turn on at all. Tell me, please, in detail, can I manage or search for yourself or wizard?
If the boiler does not work the DHW contour, then the probable cause is a duct sensor, which is installed in the cold water input nozzle in the DHW circuit. It is a turbine that could touch or score, thereby ceasing to apply the signal that water flows in the nozzle. You can independently check the condition of the sensor, breaking the water, unscrewing the supply of cold water from the unit of the aggregate. Make sure the sensor is not flared and is able to move freely rotate.
Who met such a BM-16 boiler malfunction? It is heated to a given temperature. The water in the heating system is displayed on the display, turns off, goes to circulation, the temperature is reset, but it does not turn on.
In your case, it is necessary to figure out the fault in more detail. Depending on the model, certain actions are possible.
Installed wall mounted boiler OASIS NZR-13. The problem is as follows: put the heating temperature to a maximum of 80 degrees. The output tube of heating is very hot, the batteries are slightly warm. Invited a specialist out service Center. He looked and says that a lot of gas is served, the unit quickly gains a temperature and turns off, and the water in the system does not have time (the pump in the third speed). Now
It is trying to reduce gas pressure, and something does not work. Maybe tell me where and how is it done?
Most likely, scale was formed in the heat exchanger, which leads to boiling water. The second reason is the wear of the pump, the weak rotation of the impeller, or just dirt. Check and cleaning the heat exchanger and pump.
Heating boiler ZRT 24 kW. It works fine at the first startup, but with a characteristic noise, as if the air is in the system or how boils. Subsequent warming up with the same noise, but the temperature quickly rises, and it swings. DHW is working fine. Explain what reason can be?
Most likely, the reason in the pump is jammed the impeller. Unscrew the plug and try checking the impeller manually. Another reason may be scale in the heat exchanger.
Heating boiler Oasis ZRT 24. When the hot water is turned on, hot water goes not only in the crane, but also warm the batteries, and the pump is slightly noise. All this is on the summer mode.
Most likely, the problem is in the work of the three-way valve and servo. Check if the servo rod is triggered by the end when the hot water crane is opened. Boiler malfunction or rod zaking is possible.
Model ZRT-18. Water flows from pressure valve. Who has any thoughts or who did what to eliminate the flow. In operating 6 years.
Unscrew and check the flowing valve and replace it as necessary.
Wall-mounted gas boiler Oasis 18 runs on all power, does not turn off. On the scoreboard indicator shows an open crane icon, so the gas supply is not turned off, except in manual.
Perhaps the duct sensor was blocked, or the rod of the rod in the three-way valve. Check the duct sensor and rod.
OASIS ZRT 24. During the ignition, the problem (DHW mode or heating is no difference): it turns on, it turns off with a crackle relay, even when the flame appears, and only after a few seconds, the burning is already burning smoothly, without failures. Sometimes from the first attempt is not burned, but in a mistake I have never left. The thought is to work out the health of the flame control sensor, the maintenance of the pressostat.
It is necessary to check the flame ionization sensor, as well as clean the ignition electrodes and the burner nozzle.
Problem in the circulation pump ERKO DWP 15-50 A. Soared pump snail, plastic. How to remove the pump?
Replacing the pump. To dismantle the circulation pump, you need to remove the front panel of the unit, unscrew the pump of two screws and remove the two clips on the supply of pipes input and pump output.
Gas wall boiler Oasis 24 kW. In the house (120 squares) warm floors. The floors warm up long, but then they keep warm long. The circulation pump is turned on every 5 minutes, and there is no point in it, since the burner is turned on no more often than two times per hour.

Approximately 2 cylinders for 6 days. The only one had to put an additional expansion tank, since when heated, the pressure was unacceptably rising and had to be discharged to the norm, but even after not a significant cooling of the coolant, the pressure fell below the norm, and he worked poorly. Cylinders put 2 pieces low pressure parallel. Cylinders ceased to freeze, and now burn out
Fully.

I had to immediately turn on and warm. And now there is still a strange opposing squeak. How to fix everything tell me, please?
A characteristic snoring sound can be from an expansion tank (lifting air from the spool), or the circulation pump that must be checked, to strip air through the central plug.
In the boiler VM-16, water boats at the input of the DHW, the duct sensor burned out, from the alignment of the Americans to flow with steam. Gasoviki said such a feature of these models.
The cause of such a malfunction, overheating and failure of the DHS sensor could be a heat exchanger who clogged and failed.
Bought a gas boiler Oasis BM-24. I want to translate it to a balloon (liquefied) gas. What pressure must be installed? And what other settings should be changed in the service menu? Nozzles already bought. And another question - with the help of a pressure gauge, you need to change pressure or not?
To translate the boiler to work with liquefied gas, it is necessary to replace the nozzles and in the service menu change the Fa parameter, replacing 0 to 1. Yes, the gas pressure on the burner must be about 80 mm (maximum) and 30 mm (minimum). Pressure is measured on the gas valve fitting.
Model NZR-24. Problem in self-shutdown. That is, without errors and without visible reasons, the unit spontaneously turns off, on the off display. Come on, press the power button, and it works further for a while. Then it turns off again. Intervals are always different. Maybe every hour turns off, and it can work normally for a week. It is noticed that it turns off during the ignition, that is, it is trying to regret, it does not work with something and it turns off. Iskra like normal, gas comes. The network is connected via a uninterruptible (but I tried it without it - the same thing).
On a gas pipe suitable for the boiler, is there a dielectric coupling? If there are no couplings, we advise you to put it, and if there is a unit so works, it is possible that the problem is in the control board and it is necessary to replace it.
I have a gas boiler Oasis VM-20. The house is new, connected everything except gas. I decided to fill the system. Unscrew the plug on the pump, opened the heating cranes, opened cold water. And unscrewed the fuel faucet, but water does not flow into the battery system. How do I fill the heating system with water?
Most likely, the problem is associated with an incorrectly mounted heating system, or incorrect installation of the boiler. Check the heating system and all connections or call the wizard.
Tell me, please, we want to install a wall-mounted boiler in the apartment and fluctuate between Oasis BM-16 and RT-16. The first with a separate heat exchanger, and the second with the bittermic. The remaining parameters are the same. What is the difference? What is better to take? Apartment 2/2 brick house, 68 square meters. m.
The first model BM-16 has a bitmary heat exchanger, and RT-16 are two separate heat exchanger. In boilers with a bietermic heat exchanger, there is no separate secondary heat exchanger that is only responsible for the DHW contour, which makes them cheaper, but the heat exchanger of such models is more sensitive to the quality of water and if the water is rigid, with a high salt content or a well, then the bitter unit clogs faster. In such cases, we advise you to use the RT models with two separate heat exchangers.
Tell me who knows. I can not force the ZRT-18 boiler to work with external control, that is, I put a jumper on the terminals, I remove it, and it still works on the internal temperature settings.
Initially, a jumper is present between the terminals for connecting the room temperature sensor. You must first remove this jumper (snack it) and then connect the room temperature sensor.
Tell me, please, why on the boiler Oasis VM-18 hot water boiling water, then cold? The settings do not help, the amount of water also changed.
Check the settings in the service menu, the gas pressure comes to the burner must be exhibited MAX-12 MBAR, Min-2 mbar, also a heat exchanger could also score.
Wall-mounted gas boiler OASIS NZR 16 cuts off the gas burner on the split of a second when applying a DHW or heating. No errors are not displayed and continues to work. What is the reason?
A short-term shutdown of the burner is possible for several reasons, for example, due to the gas valve. More precisely, it is possible to find out the reason only in place. Such work is not a malfunction and does not affect its efficiency and efficiency.

There are several important momentsthat need to be considered when choosing a heating equipment for its apartment or a private house. The gas boiler must comply with the requirements - to be reliable, productive, have an economical fuel consumption, easy to manage and user-friendly. Oasis gas wall boiler fully meets all consumer expectations.
Chinese heating household gas boilers Oasis is distinguished by the thoughtfulness of the work and the technical part of the device, as evidenced by consumer feedback.
One of the characteristic features of modifications is the presence of a closed fuel chamber. Air fence is carried out from the street, with a coaxial chimney. Through the pipe, combustion products are also displayed. This makes the operation of boilers as safe as possible. In addition, gas consumption is significantly reduced due to closed firebox.
Separately, it is possible to note the presence of two heat exchangers. Such a solution increases the heat heating rate for the DHW, and also allows the device to start the device in the summer, which increases its efficiency.
All wall-mounted two-circuit gas boilers Oasis have a high degree of autonomy achieved through an internal device comprising:
Oasis boilers have passed certification and received permission to operate Rostechnadzor. That did possible operation equipment of the Chinese manufacturer throughout the Russian Federation.
Malfunctions of the work of the OASIS boilers are mainly associated with omissions in the installation or maintenance of equipment. The full list of manufacturer's recommendations is in the instruction manual. The most important are the following requirements: All nodes OT. closed chamber Combustion to temperature sensor is checked for quality and compliance with the standards. The only condition of trouble-free operation is the installation and operation of the boiler for all the rules and in accordance with the manufacturer's recommendations.
Oasis gas boiler (OASIS) can work only on natural gas, the reconfiguration is excluded for liquefied, respectively, it can be installed in rooms connected to the central gas highway.
These devices are double-circuit, designed for the heating of the room and supply it. hot water For household needs. The heating temperature of the fluid ranges in the range of 35-60 degrees, the capacity of hot water supply 10 liters per minute.
Equipped with a combustion chamber closed typeDue to which the gas flow rate is largely reduced. The burner operation is controlled using automation, it contains photo sensors that control the presence of gas. For smokers, a coaxial chimney is used, the air necessary for the process comes from the street.
The design provides two heat exchanger, one for the heating circuit, the second for heating the DHW fluid. Due to this, the heating time of the fluid is reduced, and it is also possible to use the boiler in the summer.
It is possible to connect to a room thermostat that is not included in the package, it must be purchased separately. For safe operation, there are reset valves that work if the temperature of the coolant exceeds the allowable boundaries. Also, for safe operation, there are duct sensors that control the pressure in the heating circuit, in the event of non-compliance with the standards, the system operation is blocked.
Let's try to consider the error codes of the Oasis boilers, and possible reasons their appearance.
Error E1. Indicates a malfunction of ignition, possible reasons:
Error E2. It is displayed if after 8 seconds after turning on the fan, the air pressure relay does not closes.
Causes can be:
ERROR E6. Means that there is no flame. What if there was a similar problem?
It is necessary to exclude the following:
ERROR E7. Low pressure or insufficient liquid in the hot water system.
Probable reasons:
E9 error. It indicates that the pump has failed, or about invalid pressure in the system.
Check the following:
There may be a situation where the boiler ceases to warm the water, that is, from the crane when turned on, flows cold water. Most likely, the problem lies in a turbine malfunction, which does not transmit the signal to the sensor, then the flame does not approach and, as a result, the liquid does not heat up.
The turbine repair is not subject to repair, it needs to be replaced so that this situation does not happen again with the newly installed turbine, we recommend purchasing and installing a high-quality liquid filter.
