Preparatory stage
The correct solution to the question of how to light a gas boiler should begin with checking the connection according to the diagram of all necessary equipment - this is:
- Pipeline decoupling.
- Batteries, heated floors, boiler and other consumers.
- Pumps.
- Expansion tank.
- Filtration installations.
- Thermal sensors.
- Control, monitoring and safety unit.
- Uninterruptable power source.
Installation, connection and testing of the system before a test run is carried out according to the following algorithm:
- A separate branch of the electrical network for the unit is being installed.
- The place where the boiler is installed is checked. The device should be placed at the recommended distance from the wall, window and door to avoid malfunction due to cooling and drafts. The base must be strong and perfectly level, verified by the building level. There should be no flammable materials or substances located nearby.
- The unit is connected to the water supply. The equipment pipes are freed from plugs and connected to the piping using filter modules with ball valves.

- A gas pipeline is connected from the central gas main. The procedure is always carried out by gas service specialists, followed by installation of a meter with a seal.
- The chimney is connected and its draft characteristics are checked.
When all elements are connected, the unit is de-energized and, together with the system, is filled with coolant. After this, the equipment and pipes are checked for leaks. Then the thermostat is turned to the maximum level - as a result, the indication of switching operating modes should turn on.

How to light a flame on a gas boiler
When you purchase and install gas equipment, the first question that arises is how to light a gas boiler. The first start-up of a gas boiler is carried out by a specialist, from whom you can get recommendations on the use of the equipment. During subsequent starts, you can also set the required temperature using the coolant heating level control knob.
At the same time, the circulation pump is connected. Excessive noise indicates stagnant air in the pump. To release it, you need to remove the boiler cover, then unscrew the pump cover. When water appears from under the lid, screw it back on. As soon as the pump starts, automatic ignition occurs and the boiler operates normally.
The feed tap is of great importance for the operation of double-circuit boilers. Due to it, pressure is maintained so that the equipment operates without interruption.
Filling with coolant
The only sure way to turn on a Danko gas boiler or analogs from other manufacturers is to strictly follow all the rules of connection technology. The first thing to do, when all the equipment has been assembled and checked, is to fill the system with coolant - most often water.

The procedure is performed according to the following algorithm:
- The valve of the pipe, designed to supply coolant to the system, opens. This unit is usually located at the bottom of the unit, but some models may have a different device. Therefore, before starting filling, it is necessary to check the technical documentation.
- The circuit, pipeline, tank and batteries are filled with coolant over a certain period of time.
- As the system fills, the pressure is monitored using a pressure gauge. The indicator must comply with the manufacturer's recommendations. Typically, its value varies between 1.5-3 atm, but not higher than the maximum level.
- When the required pressure in the system is reached, the supply of coolant stops - the valve closes.

Note! If the system is open, it is better to fill it through the expansion tank. However, you need to know in advance how much coolant will be required. Therefore, the preliminary task of solving the question of how to turn on the boiler should be the correct calculation of the total volume of liquid being poured. Its value consists of the capacity of the heating circuit, expansion tank, pipes, batteries, boiler and other consumers.
Features of filling the system with water
To turn on the heating system, you must first fill it with coolant, i.e. water, which, after heating, will begin to circulate. A feature of modern equipment is that special manual recharge is not needed. During the first launch, you need to carefully check everything so that further work proceeds smoothly and accurately. Not only a pump is built into the boiler body, but a special tap near the pipe for supplying cold water to the system. When cold water is supplied, noise is heard, this is quite normal, there is no need to panic.
During filling, you need to monitor the pressure in the system; special sensors and pressure gauges are provided for this. Modern equipment necessarily has such additional elements, so there is no need to purchase them separately. As the gas boiler fills, the mark on the sensor rises. When it reaches 1.5-2 atmospheres, it is necessary to stop the supply of cold water, i.e., filling is completed. The pressure parameter may be different, since everything depends on the equipment manufacturer and its requirements for the operating pressure in the system. But this is not the final filling; replenishment is necessary as the heating system is freed from air pockets.

Removing air pockets
No matter how carefully the system is filled, air pockets will inevitably form in it. Therefore, the next stage in solving the question of how to ignite the boiler is bleeding the air. It is performed according to the following scheme:
- Air is sequentially bled from the radiators, starting from the top to the bottom. Special valves are opened one by one - as a rule, these are Mayevsky taps - until coolant begins to flow from them.
- Next, the procedure is transferred to the circulation pump.
- The panel on the front side is removed from the unit and a cylindrical element with a slot for a flat slot is found. The cover is loosened by turning the fasteners with a screwdriver.

- The boiler starts and heating is established - at the same time the pump should begin to emit a buzzing and hissing sound - indicating the presence of air pockets.
- When water begins to exit the cylindrical element, its lid tightens. Then the procedure is repeated 2-3 more times.
- Then it closes and the front panel is assembled.
Further, before starting the gas boiler, the system must be supplemented with coolant. Since during the procedure of bleeding the air plugs, its partial loss occurred.
Pressure testing and flushing procedures
The essence of the next stage - pressure testing - is to pump coolant into the system in order to identify its weak points, where leaks are most likely to occur during further operation. It is performed using special pumping equipment at intervals of about 10 minutes.
In this case, the pressure gauge readings must be constantly monitored. If the pressure drops, it means there is depressurization. You need to find the problem and fix it.

The second important procedure of this stage is washing. This is essentially cleansing the system of sediment, rust and other foreign particles inside the pipes, circuit and radiators. Before lighting a Danko boiler or an analogue of another line, open all the taps on the radiators and let in water under a pressure slightly higher than the operating parameters - about 4 atm. Upon completion of washing, the filter units must also be replaced or cleaned.
Inclusion
The startup algorithm depends on the type of unit installed. For the mounted version, the diagram looks like this:
- The power supply is connected.
- Gas is supplied.
- The start key is pressed.
- The operating temperature range is set.
- When the system is equipped with an electronic type of burner, the first start of heating is carried out automatically, and if there is piezo ignition, after pressing the corresponding button.

Floor-standing equipment is turned on according to the following instructions:
- The control and temperature module is switched to the on position.
- The gas supply valve opens.
- Piezo ignition is set on the temperature selector.
- In accordance with the manufacturer's instructions, the piezo button is pressed.
- The heating value is adjusted.
Important! Before turning on a floor-standing AGV, as well as a similar boiler from another manufacturer, you need to completely ventilate the boiler room, make sure the draft is working properly and open the door.

Possible problems
Often, even with strict compliance with all the requirements of the preparation technology and startup stages, the following series of equipment operational problems may arise:
- The igniter does not work. The probable cause is clogging and plaque formation. Needs cleaning. Thermocouple, solenoid valves, or supply valves may also be damaged. Needs repair or replacement.
- There is a popping noise when the main burner fires . Before turning on the gas boiler, the igniter center must be adjusted to the height of the flame, as it may be lower than the main burner. There may also be excessive pressure coming from the gas line. Another reason is a clogged or malfunctioning electrode in the electronic ignition system.

- Timing. To eliminate excessive fuel consumption, it is necessary to adjust the gas supply intensity using the control module according to the instructions.
Helpful information! The first time after startup, the heating will inevitably work with a certain amount of air, which in practice will be manifested by characteristic sounds. Since it is impossible to remove all the air from the system. However, over time, this effect will disappear due to the operation of the bleed valve on the expansion tank. The main thing is to periodically check the pressure; it should be within the recommended range.
Starting the heating system
So, you have checked the condition of the boiler and radiators, filled the system with coolant and prepared to turn it on for the first time. Then it all depends on what fuel the device runs on.
Solid fuel boiler
Starting a heating system using wood and coal is done as follows:
1. Make sure that the pressure in the system is at least 1 atm.
2. Open the damper that blocks access to the chimney.
3. Place the kindling material on the grate.
4. Load fuel into the combustion chamber.
5. Light the kindling material. Wait 10-15 minutes, then close the ignition valve.
6. When the temperature in the system rises to the desired level, adjust the thermostat so that it maintains the required heating of the air in the room.

A gas boiler
Heating equipment of this type operates on a different principle, so the first start-up diagram looks like this:
1. First of all, make sure that the pressure in the system has reached the required level. For some models this is 2-2.5 atm, for others - 4 atm. Check this information in the operating instructions.
2. Remove the front cover of the boiler and locate the circulation pump. It is a metal cylinder, in the center of which there is a wide screw with a slot for a screwdriver.
3. Connect the boiler to the network and move the power levers to the operating position. The pump will turn on and you will hear a specific hum and gurgle - this is the remaining air circulating in the system.

4. Take a screwdriver and begin to carefully unscrew the circulation pump cover. And when the hole opens, air will come out - you need to completely release it from the system.
5. As soon as water comes out of the pump, screw the cap back on.
6. The system will now automatically open the electronic gas valve and turn on the electronic ignition.

Briefly about the main thing
Before lighting a gas boiler, it is necessary to perform a number of preparatory procedures:
- Connect and check the equipment.
- Fill with coolant.
- Eliminate air pockets.
- Carry out pressure testing and flushing of the system under the action of a pressure pump.
Next, in accordance with the manufacturer’s instructions and recommendations, the unit is started for the first time. During operation, it is necessary to monitor the operation of the boiler and the system, and in case of failure, promptly correct the malfunction.

Pressure testing and washing
Pressure testing of the system is not the most necessary preparatory stage, but it is desirable, since it will show defects and leaks in advance, if any.
Pressure testing is not always done due to the lack of a special pump and the reluctance to call a team, but if the heating fails in the midst of cold weather, the costs can be much higher!
It is especially important to check a new system and one that, on the contrary, has been in use for several years.
The cost of crimping in construction companies is from 3,000 rubles.
Additionally, they may charge a fee for visiting the site (about 2 thousand rubles). By the way, a manual pressure testing pump will cost 4.5 – 6 thousand rubles.
