Guide: The gas boiler is fired by multiple motors to start the equipment. To ensure the normal operation of the equipment, we need to check whether the oil pump and filter are normal to enter the oil, and the gas furnace to check whether the gas pressure is normal. It should not be too high or too low. , Open the oil or gas supply valve.

　　The gas boiler is fired by multiple motors to start the equipment.

It should not be too high or too low. , Open the oil or gas supply valve.

　　In addition, all the valves on the flue must be opened (wind deflector or throttle valve), otherwise the blowing and cleaning will be affected, causing an accident! But the world is unpredictable. When there are problems with such a simple ignition operation, why can't the ignition be turned on? The manufacturer will explain to you.

　　What are the reasons why the gas boiler fails to catch fire?

　　1. The water level of the boiler is too low, lower than the ultra-low water level of the boiler, the boiler is automatically interlocked, and the burner does not ignite.

　　Solution: add water to the furnace to make it overflow or reach the standard water level

　　2. Natural gas leakage

　　Solution: The natural gas leaks and the burner does not ignite.

　　Generally, the burner has its own leak detection device, which can be monitored by itself.

　　3. The relevant parameters of the ignition needle are incorrect

　　Solution: reset the parameters

　　4. The gas inlet pressure is too low or too high, and the burner does not ignite.

　　Treatment method: check the inlet pressure gauge of the burner to see if the pressure is the same as the ignition pressure of the boiler

　　5. Solenoid valve failure

　　When the heating water heater is ignited, there is only an ignition sound, and there is no magnetic absorption sound of the solenoid valve "click", it may be that the solenoid valve is damaged or aging; the gas pressure is too high or too low, and it will not catch fire; the solenoid valve has stolen goods, gas Can't come out so that it doesn't catch fire.

　　Solution: Replace the solenoid valve

　　6. The ventilation duct is blocked

　　Solution: First check whether the exhaust duct is blocked. If not, check whether the fan and air pressure components are damaged. The fan and air pressure switch are components of the exhaust system. If there is a problem, they need to be replaced.
