Within the framework of of this material the gas burner device of the AGU-11.6 model with a standard set of automatic control and safety means will be considered. The main technical specifications of this solution and the algorithm for its launch. In addition to this, the material contains the cost of this component of individual heating systems, its strengths and weaknesses are considered.
The considered gas burner device AGU-11.6 is intended for the repair and modernization of outdated individual household boilers. That is, if for some reason the gas combustion system is out of order and you need to urgently restore its operability, then you can install such a burner. Again, it is first necessary to clarify the compatibility of the boiler and AGU-11.6.
Also, such a gas combustion system is used by default in some models of modern household boilers. One of these is AOGV-11.6. His key feature in that it is equipped with two heating circuits of the coolant. One of them is designed for heating and is used in the cold season, and the second is used for heating water all year round.
Any modern gas burner device according to the method of supply air environment can belong to one of two groups. The first one is called injection. In this case ventilation unit is absent, and the air supply is realized due to the special design of the burner in a natural way. It is this principle that is implemented in ASU-11.6. The second group is based on forced air supply, and a fan is necessarily included in the burner.
As the operating experience of recent years has shown, it is no longer economically feasible to use injection systems for burning gaseous fuel. They have low efficiency and increased consumption of natural gas. Therefore, in most cases, when modernizing heating systems, it is precisely those boilers that are equipped with burners with forced ventilation and have improved technical and economic indicators. At the same time, the cost between the first and second groups is not so significantly different.
The automatic gas burner device of the AGU-11.6 modification has the following basic technical specifications:
Automation of gas burner devices of the AGU series has the following safety circuits:
The AGU-11.6 burner complete with a standard set of safety and control automation equipment is started as follows:
At the moment, such gas-burning devices for boilers can be purchased for 5000-6000 rubles. Moreover, if you choose on the Internet, then the price will be lower, and if you wish, you can purchase such a solution even for 4700-4800 rubles. Well, in specialized retail outlets, AGU-11.6 with a guarantee can be bought for 5700-6000 rubles. Again, in the first case, shipping costs must be added to the cost of the burner. At the same time, warranty obligations are not always possible to provide. Therefore, it is recommended that AGU-11.6 and other similar devices be purchased at specialized retail outlets.
The considered gas burner device marked AGU-11.6 has one significant drawback - it is an increased gas consumption, which is explained by the presence of an injection method for supplying air. The advantages include the reliability of the system, low cost, availability of automation and versatility. As noted earlier, today it is not recommended to use such a burner due to its low technical and economic characteristics.
Within the framework of this review, a gas burner device of the AGU-11.6 model is considered. Although such a fuel combustion system is used in modern boilers, from an economic point of view, its use is currently impractical due to the fact that the gas consumption is overestimated. Otherwise, this is a reliable and time-tested solution.
Comfortable summer cottage, spacious garage, private cottage, multi-level apartment - gas boilers warm the lives of millions of people. The heat of powerful units is constant, familiar and you don't think about it until the temperature in your home or workroom suddenly drops. Adjustment and adjustment of gas boilers carried out from time to time will avoid accidents and breakdowns.
What is good for a Russian is 20 mbar for a European
In the countries of Russia and Europe, the main gas pressure standards differ. Abroad, this value is constant and is determined at 20 mbar. However, keeping the same level of heating in Russia both in summer and in winter is a utopia. So, in the warm season, the indicator decreases to about 13 mbar, and with the arrival of frost, pressure surges and interruptions in the supply of gas fuel are observed in the network.
Foreign manufacturers of gas boilers could not close their eyes to the climatic conditions of their neighbors and adjust imported boilers to certain sensitivity ranges. This operation is performed at the factory during the assembly of the mechanism. In addition, a special gas valve allowing you to adjust the pressure if necessary. Initially, it was conceived as a way to save fuel consumption, but Russian citizens use it as a means of preventing an emergency shutdown. gas boiler due to a drop in line pressure.
Himself a traffic controller
The main steps for setting up and adjusting the operation of a gas boiler of any configuration must be performed by a specially trained person. But there are a number of operations that the consumer of thermal energy can cope with - for example, while waiting for the arrival of the master.
The actions that bear the general name of adjusting and adjusting gas boilers also include heating the boiler, opening the chimney gate, checking the safety automation, transferring the dial gauge installed on the gas pipeline.
Note to the owner
Commissioning of a gas boiler is inconceivable without analyzing the exhaust and gas flows going to the supply. The adjustment cannot be considered complete if the optimum air and gas balance is not found. Who wants to pay for fuel that escapes without a trace into the atmosphere? Who will be heated by inefficient heat? Are there citizens interested in deliberately reducing the service life of the heater?
In order to distract an accident from your home or office, you need to make adjustment work a routine matter. Make it a rule: once in a certain period to carry out a thorough comprehensive inspection of the gas boiler, its parts and accessories. The maximum achievable boiler efficiency will be maintained with an acceptable quality of operation of the device. When setting up a wall-mounted or floor-standing heating boiler, make sure that additional thermal insulation is not required in the combustion room and that the heat losses inevitable during the operation of the boiler are at an acceptable level.
With the beginning of the heating season, the owner of a private house must switch the heating boiler to operating mode. The operation is not the most difficult, since all instructions for setting up the unit are necessarily indicated in technical documents... In our article, we will tell you what to look for when setting up equipment and how to get the boiler to work with maximum efficiency.
You need to decide on the settings for a gas boiler even before buying it. We recommend starting with the power of the equipment. The features of your home are of great importance. The main condition for the normal and uninterrupted operation of such a unit is the availability of a centralized gas supply. Naturally, you can try to use imported gas cylinders, but this will significantly increase costs. In some cases, it is even cheaper to purchase electrical equipment for heating a building than to purchase gas cylinders.
Heating boilers are single-circuit and double-circuit. In the first case, we recommend purchasing an additional indirect heating boiler. Only then can the unit be used to heat sanitary water. The best option considered a purchase double-circuit boiler, which has all the necessary functions for heating a building and water. Its key feature is the transfer of the priority of operating mode control to the hot water supply. In other words, after opening the hot water supply system, heat is supplied to the main circuit, which also includes heating system, stops.
There are some features of choosing a floor-standing and wall-mounted boiler. Wall-mounted equipment is less powerful, so it will not be enough to heat rooms with a total area of over 300 square meters. In this case, you will either need to purchase another boiler, or mount a floor-type gas boiler. In stores, you can buy floor-standing units of any capacity.
The power of a heating boiler is a key factor that affects the level of heating of the premises, as well as the durability of the equipment and the safety of its operation. First of all, it is necessary to determine the heat loss through the ceiling, walls and windows. Part of the heat energy goes through the ventilation system, which should also be remembered. It is very difficult to carry out such calculations with maximum accuracy on your own, you cannot do without the help of specialists.
However, there is a technique that allows you to approximately calculate the required power indicators. If the construction of the building was carried out in accordance with all safety and energy saving requirements, then about 100 W of heating equipment power is required to heat one square meter. Accordingly, it is necessary to buy a new gas boiler based on this ratio.
To select a boiler, take into account the characteristics of your building. After all, the power will depend on many factors, be it the thickness of walls and ceilings, the presence of plastic or wooden windows, as well as their insulation. The difference between the outside temperature and the room temperature is of great importance. So, if inside the temperature changes insignificantly, then outside the amplitude reaches huge values. Even in winter, abrupt transitions from plus 10 to minus 20 degrees are possible.
Give preference to modern units. And the reason is not only in the quality of such equipment, but also in the availability of additional functions, for example, LCD displays. In this case, it will not be difficult to set up a heating boiler, since the monitor shows the main parameters of the device's operation - fan speed, actual and set water temperature, and much more.
One of the most common hardware power problems is clocking. This phenomenon occurs when the unit you have selected has too much power. In this case, there are only two ways out - either purchase a new gas boiler, or try to do the adjustment with your own hands. The first option is preferable, however, the second is also used very often.
Boiler cycling is a situation where the boiler starts up on its own too often. This is due to a too strong increase in the temperature of the coolant.
Clocking is fraught with serious consequences. Inadvertent switching on of the equipment causes excessive gas consumption, in addition, excessive wear of the equipment is observed. However, solving the problem is very simple - adjust the gas supply to the burner to the minimum level. Check the gas supply level regularly and, if necessary, re-adjust the gas boiler.
Each boiler comes with its own instructions, which describe in detail how to do this. Usually, there are special screws on the gas valve that are responsible for the intensity of the fuel supply. On modern models all settings can be made directly from the LCD display, making it even easier and faster.
Setting the gas boiler allows you to set the optimal temperature regime in the premises. The only condition is the presence of a thermostat, the task of which is to regulate the burner power. The thermostat is connected to a temperature sensor in the room. You must first set the required temperature value that is comfortable for you. After that, you can enjoy the warmth by reading books or watching your favorite movies.
There are some restrictions when using thermostats. For example, this device allows you to set the temperature in only one room. To eliminate this disadvantage, it is required to install a thermostatic valve in the supply pipe in front of each heating radiator. Due to the narrowing or expansion of the working medium located inside the valve, the cross-sectional area of the pipe changes. Such valves react to the slightest temperature measurement, even an increase in the number of people in the room can lead to a narrowing of the working medium.
Failure of thermostats can cause simultaneous shutdown of all heating radiators. This will lead to the termination of the circulation of the coolant in the heating equipment circuit. The jumper tube or bypass must be installed in advance to avoid these problems.
Modern gas boilers are equipped with an automatic selection of the operating mode depending on the presence of people in the rooms. This allows you to maintain the temperature at a certain level even during a long absence of the owners. This setting can be used only if the system is periodically monitored by neighbors or relatives. This is due to the fact that in the event of unforeseen problems, for example, an emergency shutdown, the entire heating system of the building will fail.
As practice shows, there can be many reasons for turning off the boiler:
Therefore, regular monitoring is necessary. Otherwise, the system may fail, which will lead to huge financial costs. Naturally, neighbors will need to explain how to properly adjust or adjust the gas boiler in a given situation. Then you can expect that nothing will happen in the house during your absence.
Automation ASUK is a complicated modification of ASU. This is one of the most common automatics. Due to its simplicity and reliability, it has proven itself from the good side. It has flame extinguishing protection and a thermostat. Suitable for almost all types of boilers.
The disadvantage is that a bimetallic plate is used in safety automation as a sensitive element. The plate periodically burns out and requires automatic adjustment. Automation of ASUK is equipped with a thermostat. The thermostat valve is closed by means of a bimetallic rod. Temperature adjustment is carried out by turning a flag or an adjusting screw. The gas supply to the burners is opened with a plug valve. It must be lubricated during maintenance.
Customization.

The safety automation of the SABK boiler is installed on many boilers, has established itself as a reliable equipment. The plant produces several modifications of automation. All of them have protection against flame extinction, protection for the absence of traction, and a thermostat.
Peculiarities.
Two bimetallic plates and two ball valves require periodic adjustment. Damage to the diaphragms of the main valve and drying out of the gland packing of the thermostat lead to gas leaks, which make it impossible to operate the boiler. It is necessary to monitor the condition of the impulse pipes and their fastening. Some modifications of SABK automatics are equipped with an electromagnetic valve, a thermocylinder, a thermocouple, an electric traction sensor, an autonomous power source and a piezo ignition.

Automatic equipment of the AGU series is the oldest and simplest modification of gas burners. It is used for installation on brick ovens, small boilers of thermoregulation bases. Has small dimensions, simple design, unpretentious and durable. There is only protection against flame extinguishing. Modern modifications of this burner (AGU-P) are made from many parts with rivets and bolts. This complicates the design and reduces reliability.
AGU-P is equipped with a draft sensor. The way of attaching it and driving it to the button lever raises many questions. The bimetallic plate periodically burns out and requires adjustment. The plug valve must be lubricated during maintenance.

Boilers of the old modification and completeness are extremely rare in Novosibirsk. At the time of the first gasification of the private sector, they were widespread. Now AOGV is a rarity. Decades of operation speak about the reliability of this device. Currently, there are no spare parts and components on sale for them. Repair and maintenance specialists avoid working with them and recommend replacing the boiler. The reason is that if a part breaks down during disassembly of the automation, it will be costly and time-consuming to restore it.
The boilers of the new modification are manufactured using all the latest developments: control unit with solenoid valve, thermocouple, electric draft sensor, modern burner device and heat exchanger, capillary thermal sensor. A distinctive feature is a mirror for observing the pilot burner and a long thermocouple.
The boilers have disadvantages inherent in this series: loss of electrical contact between the thermocouple and the coil, not a repairable automation unit. In addition, an extended thermocouple is used.
