The installation of gas equipment solves two problems at once: to heat the room and provide hot water supply. But what if there are problems with the equipment? Why does the gas boiler go out? It’s unpleasant when this happens at the height of the heating season. You can freeze slowly, or you can study our recommendations and try to fix the problem on your own.
Why does the boiler go out
Reasons for extinguishing a burner or pilot can be either internal or external. Such malfunctions do not depend on the brand of production. Any Lemax, Conord, Proterm, Siberia models may be subject to them.
Malfunctions differ in different models depending on the combustion chamber - closed and open type. Let us consider in more detail the causes of breakdowns and their solutions. First you need to know that the burner goes out when the protective automatics are triggered. If a malfunction occurs in the system, one of the sensors is triggered - the device turns off.
- No draft in the chimney.
- Low gas pressure.
- Extinguishing due to external factors (gust of wind, reverse draft).
These problems are typical for the Danko, Aton, and Ross models.
Wall and floor electric-gas boilers are equipped with a large number of sensors. Therefore, protection is triggered in such situations:
- Stop circulation of the coolant.
- The air supply has decreased or stopped.
- Voltage drops in the network.
There are parapet-type devices that stop operation for these reasons.
Problems of atmospheric open boilers
If your device has been working properly for several years, and now the burner lights up and goes out, look for a problem among the indicated reasons.
Traction problems
To check its presence or absence, light a match and bring it to the control window. If there is traction, the fire will deviate to the side, in the absence it will burn evenly.
Which leads to a violation of traction:
- Weather. Wind, rain, atmospheric pressure affect the operation of the chimney. Foreign objects entering the shaft can lead to reverse traction and carbon monoxide poisoning. It is necessary to clean the passage, install a check valve that will protect the system from such situations.
- No good ventilation. Natural ventilation is required to maintain a flame in an open chamber. The air intake is from the room. Therefore, it is important to have a window with a window. Open the window to resume the work of the equipment.
- On the ice. Condensate accumulates on the walls of the mine, and then freezes. As a result, the ice layer interferes with normal traction and smoke exhaust. The accumulated layer is knocked down, and the walls of the shaft are insulated to avoid such cases.
- Soot accumulation. This often happens while connecting a solid fuel and gas boiler. If you live in an apartment building, it is better to contact the utilities.
- The pipe burned out. Only a complete replacement will help.
As a result of the development of neighboring plots, a tall building can block your house, and the chimney gets into the leeward zone. Therefore, the recommended shaft height is 2 meters above the roof.
Head freezing
The tip is the part of the boiler that is outside. In the event of severe frost, the ice freezes inside and out, then it is impossible to bring it down. Therefore, the head is removed and thawed. In this condition, the device can be started, but first you need to warm up the unit. To do this, turn on the gas valve, then, gradually unscrewing, light the burner. Gradually increase the feed until the structure warms up.
Low gas pressure
If the burner constantly flashes and goes out, it means that the system has an unstable gas supply. Wait until pressure is restored.
Other reasons that the flame goes out:
- Gas leak at the joints. If you smell it, turn off the shut-off valve and contact the repair service.
- Clean the gas filter of the Mimax, Keber or any other boiler, try lighting the burner again.
- Poor ventilation is the reason the wick goes out. How to adjust the air supply? Open a window or window, install a ventilation valve.
- Blockage or malfunction of the counter. After repair, the pipeline may become clogged inside the meter. In the event of a breakdown, you can hear crackling, noise, on the screen the numbers jump in jerks.
Independent work with the counter is strictly prohibited. Call gas workers.
Air supply problems
After switching on, the wick went out? If this happens often, check if enough air is entering the system. As we wrote above, an open camera will not function without proper ventilation. Open the window and look at the flame in the burner. If it has stabilized, it means that there is not enough air under normal conditions.
Why does this happen:
- Recently installed plastic windows. The bags are airtight and do not allow air to pass through, therefore it is recommended to install a ventilation valve.
- You have replaced the door to the room. According to the norms, the gap between the lower part of the door and the floor should be at least 5 cm. When completely blocked, the air flow stops.
- Simultaneously with the boiler, a powerful (forced) hood is activated, which pulls the flow. Turn off the hood while the heating equipment is operating.
With a strong wind, parapet boilers suffer. Part of them is hung on the wall of the house from the outside, thus removing combustion products. If wind gusts blow into one of the gratings of the device, then reverse thrust may occur. To solve the problem, identify the windward side and overlap the grille on this side.
Problems turbocharged technology closed
If you installed a new smokeless device, but the focus periodically fades out in it, it is worth checking the components and parts. The problem can be identified by the following signs:
- When the igniter ignites, it periodically goes out. This indicates a thermocouple malfunction, which affects the operation of the gas valve. The thermocouple is made in the form of a tube of copper. At the end is a bimetallic part. When different metals come into contact, a voltage of 20-50 MW rises, which keeps the gas valve open. In the event of a breakdown, the thermocouple is not repaired; replacement is required.
- Floor unit "Hephaestus", "AOGV", etc. It’s not at all kindled. Check the automation and wiring from the draft sensor to the automatic unit.
- Ignition occurs with pops, a yellow flame erupts - this is a blockage of jets. They can clog with soot, dust, dirt. You can clean them yourself if you understand gas equipment.
- Circulation pump malfunction. In this case, the fire will go out, or the ignition will not happen at all. Diagnosis and replacement of the unit.
- The traction sensor is broken or clogged. This flat element is connected to the fuel valve. Close the lead contacts and light the burner. If a fire occurs, then you need to change the sensor. During oxidation, the contacts are smoothed out with fine sandpaper.
Malfunctions of gas equipment
If the equipment is additionally connected to the network, check for voltage. Turn over the plug in the socket to change the phase.
What are the signs of failure?
- The unit does not work, indicators do not light.
- The LEDs light up, the display works, but the ignition does not occur.
- The burner goes out after ignition.
Inspect the safety block. Found a burnt item? Install a new fuse - it is often glued to the front panel. If the actions did not help, then:
- Clean the heating filter. To do this, turn off the product, turn off the valves and rinse the filter under running water.
- To remove the air plug or excess water in the pump, unscrew the main screw in the center. Bleed the air, rotate the pump rotor with a screwdriver. When water drains, return all parts to place.
- Problems with low pressure in the system can be fixed by pumping air into the expansion tank. The product is located in the interior of the structure. As a result, the pressure should be 0.2 bar less than in the general system.
If the burner goes out due to minor problems, you will cope with them thanks to our recommendations. It is better to entrust the replacement and repair of the main components to the repairman. Gas boilers are a high-risk technique, so observe safety rules.
