Types of gas boilers
Many owners of private houses choose gas boilers for heating. This choice is explained by the economic benefits of using natural fuel and the ability to heat a large house using one device. A gas boiler does not require constant maintenance of the combustion process by adding fuel; during its operation, soot and soot are not formed. There are different types of boilers:
- Wall-mounted. They have compact dimensions and light weight, so they can be installed in a small room (kitchen, pantry). A heating system operating through a wall-mounted unit does not require the additional installation of a pump, expansion tank and boiler, so its installation is simple.
- Floor-standing. They are characterized by greater power than wall-mounted ones, therefore they are optimally suited for heating large areas. They are equipped with cast iron or steel heat exchangers that have a long service life and are resistant to corrosion and mechanical shock. Floor-standing units can be equipped with both atmospheric and inflatable burners. The second option allows the use of liquid fuel as a raw material.
Gas heaters are also divided into single-circuit and double-circuit. A system with two circuits not only heats the room, but also additionally provides hot water supply. Single-circuit ones do not have such an additional function; in order to have hot water in the house, the system will need to be equipped with a boiler.
Each heating boiler has a combustion chamber. Depending on the design, it can be:
- Open. It works due to natural draft, so it is only suitable for rooms with a vertical chimney. Needs effective ventilation, providing a sufficient flow of oxygen and preventing combustion products from entering the room.
- Closed. Uses forced traction in work. The presence of an electric fan and a coaxial chimney allows combustion products to be removed from the chamber. All wall-mounted gas appliances are equipped with a closed chamber.
Regardless of the type of gas installation, it is part of a single heating system, which also includes pipes, radiators, a pump, an expansion tank and filters. Before lighting a gas boiler, you need to make sure that the elements are securely connected.
Why does a gas boiler go out and turn off: the main reasons
Setting up the heating system
You can establish efficient and stable operation of the heating system after the boiler has been successfully started.
To set up, you will need to understand the control valves. In most cases, the batteries that are located furthest from the boiler do not have enough heat. This can be corrected if the supply of heated coolant is distributed evenly. To do this, screw in the taps to adjust the first two radiators. The tap of the first radiator needs to be screwed in half, and the subsequent ones a little less. Observe the effect achieved. It may take several days of adjustments and adjustments to get each radiator to heat evenly. However, in general, the system at this stage already works normally and warms the room.

Pre-launch activities
The location for the gas boiler is chosen depending on its modification
The position of the boiler is selected according to safety standards, away from fire hazards. The distance to wall structures is prescribed in the manufacturer's instructions. The body of the unit is set taking into account the horizontal and vertical levels, since if it is distorted, the work is disrupted.
The equipment is connected to the water supply and gas mains, ball valves and filters are installed using pipes. Before lighting the boiler, install the power supply and install a separate socket. First connect the chimney pipe and check for the presence of draft.
Varieties
There are three modifications of Zhukovsky AOGV 23 boilers:
- Economy _ Floor-standing unit with Russian automation, tubular heat exchanger. There is a temperature sensor.
- Station wagon. Italian SIT automatic equipment, modulated burner, coolant overheating sensor are installed.
- Comfort. In addition to all the options of the Universal models, the boilers have the possibility of remote control, a room thermostat, and protection against exceeding the coolant temperature.
Boilers of the Comfort modification can be distinguished from other varieties in appearance - they have a rectangular cross-section of the body, while Economy and Universal are round.
What functions does the Zhukovsky gas boiler AOGV 23 have?
The abbreviation AOGV 23 stands for Domestic Gas Heating Apparatus with a power of 23 kW. This is a single-circuit floor-standing unit capable of efficiently heating a room up to 200 m2 .
Such possibilities are optimal for use in a private house, cottage or other premises. The boiler is designed to perform only one function, which allowed the manufacturer to eliminate all unnecessary parts and unused design elements.
This increased reliability and reduced the number of failures and breakdowns. In addition, a feature of AOGV 23 boilers is energy independence.
In the event of a sudden power outage, the boiler will continue to operate as usual, which is important in the Russian winter . This feature significantly increases the reliability of the home heating system.
At the same time, the lack of power supply requires a specific location of the radiator system, since the coolant will circulate naturally.
The combustion chamber of the boiler is atmospheric type, with air intake directly from the room and natural smoke removal using stove-type draft.
Household antifreeze is used as a coolant, which increases the reliability of the heating system in severe frosts.

Filling the system and removing plugs
After installing and debugging gas equipment, you cannot immediately turn it on. Before turning on the gas boiler, the system must be filled with water. To do this you will need:
- 1. Open the tap located at the bottom of the boiler next to the cold water connection.
- 2. Wait until the system is filled with water. This happens slowly and requires a certain amount of time. During the process, it is necessary to control the pressure level. To do this you need to use a pressure gauge.
- 3. When the level of 1.5−2 atm is reached, close the tap.
During filling, air pockets may form inside the system. To prevent their occurrence, the procedure should be carried out at a positive temperature. During the cold season, the room where the boiler is located needs to be preheated.
Even if all the conditions for preventing traffic jams have been met, it is imperative to remove air from the system using air vents specially designed for this purpose, located in the upper fitting of the radiators. Depending on the design of the batteries, these can be Mayevsky taps or automatic valves.
To release air through the tap, you will need to unscrew it using a mounting wrench, after placing a water container under it. Air mixed with water will begin to come out of the radiator. After about 5-7 minutes, when a steady stream of water flows from the tap, it should be closed.
A similar procedure must be done with all radiators connected to the heating system. Then repeated pressure measurements are taken and the water tap is opened. The pressure gauge readings may be slightly above average, but should not reach the maximum. Otherwise, when the water starts to heat up after turning on the boiler, the pressure will become extremely high and the heating system will fail. If you have automatic valves, you won’t have to make any special efforts. You just need to wait a while until the air comes out of the line.
Which is the best wall-mounted gas heating boiler: description of units
For which rooms is it best suited?
AOGV 23 boilers are optimal for use in private homes, public or commercial premises. They require a separate room with ventilation, so installing the units in apartments is not recommended.
Also, production workshops with a large number of openings and technological hatches that disrupt the air exchange regime and create drafts are not suitable for operation. They often cause flames, which stops the heating system from working and creates the risk of gas leaks.
The best option is a separate room in the basement (ground) floor, with a window opening and an area of at least 8 m2.
Possible startup problems
- The gas boiler slams when the main burner starts.
The most common problem, the cause of which is most often clogging of the igniter (dust, combustion products, etc.).
It is recommended to call a specialist to clean it. The reason may also be that the pilot flame is too low: below the main burner. When using electrode ignition, the electrode may be clogged or faulty. In rare cases, the cause may be excess gas pressure in the line. It is important to understand that slight, barely audible pops are characteristic of most models of gas boilers that do not have a sound insulation layer.
- Only the wick is lit and cannot light the main burner.
The reason may be the same clogging of the igniter or its incorrect installation, when the flame simply does not reach the main burner. Clean the pilot nozzle (it is advisable to entrust this to a specialist) and check the operation: its flame should reach the main burner and simultaneously “wash” the thermocouple. Sometimes the reason lies in a malfunction of the thermocouple, which does not open the gas supply.

Starting the device
When all the preparatory stages are completed, you can proceed to launching the gas equipment. The sequence of actions depends on the type of boiler. Attachments such as Celtic, Protherm, Beretta, Ferroli, Bosch need to be connected to the network and the gas valve must be unscrewed. After this, press the “Start” button, using the “+” and “-“ buttons, set the desired temperature.
These models have a hot water supply mode. When switching to it, the electronic burner will automatically light up. To pierce ignition, you will need to press the flame regulator and hold it for a few seconds, then activate the piezo button. Sometimes ignition may be blocked due to air in the system. To unlock, just press the “Restart” key. The inclusion of parapet models of the ATON type occurs according to the same scheme. If the kit includes a remote control, you can set the boiler on fire using it.
The algorithm for launching floor-standing devices will be slightly different. Before lighting a floor-standing gas boiler such as Baxi, Siberia, Buderus, Lemax, Conord, you need to ventilate the room, check the presence of draft and the position of the control and temperature selector. It should be in "Off" mode. Then open the gas valve, switch the selector to the pierroignition mode and press it for 5 seconds. At the same time press the play button. After the burner lights, you can adjust the temperature.
Gas heating systems should not be turned off for a long time, especially during the cold season. The effect of low temperatures will provoke freezing of the heating system and failure of its components (pipes, radiators, boiler). If you plan to not use the gas installation for a long time, it is not recommended to turn it off, but to set the temperature to the minimum. In this way, with minimal fuel consumption, defrosting of the heating circuit will be avoided.
Even if the gas supply from the pipeline stops during the absence of residents, serious problems will not arise. The control sensors that modern gas heaters are equipped with will block their operation, preventing possible problems.
Price range
The cost of the Zhukovsky AOGV 23 boiler depends on the specific model and ranges from 20-24.4 thousand rubles. This price does not include the chimney. When purchasing, you should immediately clarify the equipment of the unit so that you do not have to urgently look for the necessary components.
In addition, additional costs will arise for concluding a warranty agreement.
It is not recommended to neglect this action, since subsequently you can spend a much higher amount on repairs.
NOTE!
Many users rely on their own skills and knowledge, intending to repair the boiler themselves. It must be remembered that unauthorized actions with gas equipment may entail administrative liability.
Important Operating Instructions
In terms of operation, gas boilers with a closed combustion chamber are considered safer. Their firebox does not communicate with the room air. However, the power of such boilers is significantly inferior to the power of boilers with an open combustion chamber. Therefore, in private households a second type of boiler is often installed.
The choice of future coolant depends on the goals and operating conditions of the system. If the boiler is expected to be turned off frequently, then it makes sense to think about using antifreeze
The operation of such boilers requires compliance with safety precautions. So, to install a powerful floor-standing boiler, it is customary to use a separate room with a certain size. The boiler is mounted at some distance from the walls. Nearby walls should be protected with fire-resistant material to prevent fire.
A ventilation system must be installed in the boiler room. There should also be a source of natural light. The width of the entrance door must be at least 80 centimeters. The chimney is laid in accordance with the instructions for the boiler and from heat-resistant material. The chimney must rise above the roof ridge by at least half a meter.
One safety measure is to install carbon monoxide detectors. The gas detector will promptly detect the leak of a volatile toxin and warn users about it. It can also be configured so that the ventilation is automatically turned on and the gas supply is turned off. Modern automation allows the implementation of a variety of smart systems.
If the temperature, pressure or gas sensor fails, you must immediately turn off the boiler and call a service technician. Using a boiler without these devices is fraught with serious negative consequences.
SNiP requirements state that a gas boiler must be connected to the main line using a copper pipe or a bellows hose. In this case, a faucet must be installed
If signs of a gas leak are detected, you must immediately turn off the gas tap and open the windows to ventilate the room. Do not turn on the light and try to illuminate the room by lighting matches or a lighter.
The gas boiler must be serviced at intervals specified by the manufacturer. Information about the necessary procedures is indicated in the instructions for the device. For example, you need to clean the chimney, remove scale from the heat exchanger, or clear the fumes from the burner. Then the boiler will last a long time, and the risk of serious malfunctions will be significantly reduced.
When using a gas device, do not turn it on at maximum power for a long time. This may result in the release of steam, which is unacceptable.
Sometimes the boiler begins to make unusual noises and vibrations. This may be due to the operation of the fan. We warn you that all actions that require disassembling the boiler casing automatically deprive the owner of the right to warranty repair or replacement.
However, the owner of the unit needs to monitor the operation of mechanisms and systems that protect the boiler from fire. It is necessary to maintain the temperature in the circuits at around 50 degrees, which significantly reduces the likelihood of mineral deposits forming on the internal surfaces of pipes and devices.

Flame and draft sensors
Flame and draft sensors work on this principle. The draft sensor reacts to deteriorating smoke draft and transmits an impulse to the control system. It is located in the smoke hood. Equipped with a plate made of an alloy of two metals: iron and nickel. When draft deteriorates, flue gases accumulate and heat the plate. It becomes deformed, the contacts open, and the flow of fuel into the combustion chamber stops. When the temperature decreases, the plate returns to its normal state.
The temperature sensor works on the same principle. When the water in the boiler heats above the set temperature, the lever mechanism is activated and the temperature regulator valve closes. The gas supply stops and the burners go out.
When the water cools, the sensor bellows contracts, the lever mechanism is activated, the temperature regulator valve opens, gas begins to flow, and the burners light up.
Floor steel models Conord
Let us immediately note that all boilers of this brand are produced in a floor-standing version. “Steel” boilers are those whose heat exchanger is made of steel. It is easy to find such a device in a catalog or price list by the marking, which begins with the letters “KS” (steel boiler).
For example, it is the steel heat exchanger that is installed in the boiler of the KSC-G-16 brand.
Here the letter “C” denotes the cylindrical shape of the heat exchanger, “G” is the type of fuel (gas), and the number “16” is the power in kilowatts.
The presence of the letter “B” in the marking (for example, KSC-GV-20) means that the boiler is 2-circuit.
Boilers with a steel heat exchanger are lighter and heat up quickly. However, they are less reliable and not as durable as cast iron. A significant disadvantage of steel is its susceptibility to corrosion.
Winter launch features
If you have to start the boiler in winter, you will need to slightly change the sequence of work:
- it is necessary to warm the premises to above-zero temperatures using electric heaters;
- fill the short circuit closest to the boiler with coolant;
- warm up the coolant to a temperature of 20-23 degrees (no more);
- gradually move further along the circuits, heating the coolant to the above temperature;
- after all circuits are filled, you can turn on the unit in operating mode.
Care tips and advice
Proper maintenance of the boiler, performed regularly, will help keep it in working condition for a long time and avoid various accidents and accidents. Otherwise, the unit may break even in the first year of operation. Performing several operations will prevent this from happening:
- even during normal operation of the boiler, you need to contact one of the organizations carrying out work in this area, so that a technician inspects the device for gas and water leaks, the condition of the sensors and chimney, and, if necessary, carries out repair work;
- You should always monitor the water pressure inside or at the outlet of the system. If it drops below 0.8 bar, then water needs to be added;
- The addition of water to the system is usually carried out directly through the boiler, where there is a special tap. In this case, the pressure of the added water must be greater than the pressure of water from the boiler. The supplemented water should only be cold (up to 35°C).
For your information! To spend winter evenings warm and comfortable, you need to properly care for your boiler and also know how to light it.
Depending on the model and manufacturer, this process will be slightly different due to differences in design. This can be clarified in the instructions supplied with the device.
Device
The operating principle of the AOGV 23 boiler is based on heating the coolant using an atmospheric burner . Entering the tubular heat exchanger, the liquid reaches its maximum temperature, after which it is discharged into the heating system.
The movement of the coolant occurs under the influence of the upward thermal movement of heated layers, therefore the placement of all pipelines must be planned with a certain slope. To set the temperature to a given value, a three-way valve is installed, which mixes a certain amount of colder return water into the heated coolant.
Natural circulation is unstable and ineffective, so many owners install an external circulation pump to stabilize the system.
