Boiler gas valve adjustment

If earlier the boiler was adjusted simply - turned the valve on the burner and increased or decreased the gas pressure, then modern automation does everything by itself. But even in it there are malfunctions that require adjustment of the automation. Consider how a modern gas boiler operates.

Description and functions of a gas boiler

A simple heater consists of a heat exchanger chamber, a gas burner and ventilation. The operation of all these systems is controlled by automation.

The safety device of gas boilers has a multi-stage protection system:

1. When firing up, you need to not only turn the gas supply knob, but also hold it for a while until the solenoid valve (6) operates. This prevents accidental gas leakage in the device.
2. The return draft sensor (8) responds to the flow of fire from the burner into the room. This can occur with sudden gusts of wind, a clogged chimney and burner malfunction. Thanks to this controller, the gas flow when the reverse draft occurs is automatically turned off and people can not get carbon monoxide poisoning.
3. The temperature sensor (7) protects the boiler from overheating, including gas as necessary. Thanks to him, the temperature in the heating system is maintained at the mark that is set by the user.

Control systems in gas boilers can be autonomous or volatile. The second require a connection to the electrical network.

Gas boiler adjustment

If the automation began to work incorrectly, there were malfunctions in its functioning, then you need to find the reason and either adjust the control system, or replace the defective elements.

IMPORTANT! Do not disregard malfunctions, even if they occur only occasionally. It can cost the life of you and your loved ones.

Consider the most popular problems that you can fix yourself:

• "The boiler warmed up wonderfully in the fall, and in the winter it is cold in the house." This, in fact, is not a breakdown, but just the need to control the heating temperature. In the body of any gas boiler there is a thermostat. It may look like a rotating handle with a scale, buttons with a temperature screen, a scale with a slider on it. It is enough to set a higher heating value, as the house will immediately become warmer.
• “When firing up, the solenoid valve does not work, how much do not press on the handle.” The most common failure requiring valve replacement.
• “The boiler burns normally, but after some time, cotton is heard and everything turns off.” As a rule, here we are dealing with the operation of automation. But the reason for the "cotton" will have to find out. It’s best to invite experts.

IMPORTANT! Do not stick the defective EM valve and do not jam it! He is responsible for the gas supply, and if you fix it, the rest of the automation will be useless. When the burner goes out or when the draft is back, you risk simply suffocating.

Conclusion

In conclusion, it should be recalled that all gas equipment is a source of increased danger. Do not spin anything in the boiler control system yourself, interfere with the operation of controllers, burners and sensors. Gas is invisible and not tangible, and its leakage is much more difficult to detect than faulty wiring or leaking water pipes. If it is necessary to install, replace, repair or adjust the gas boiler, it is better to invite specialists.
