When the ignition switch of the wall mounted boiler enters the working state, the fan starts first to create a negative pressure difference in the combustion chamber. The air pressure switch sends the command to the water pump. After the water pump starts, the water flow switch sends the command to the high-pressure discharge device. After starting, the command is sent to the gas proportional valve, and the gas proportional valve starts to start. Due to the presence of negative pressure in the combustion chamber, natural gas does not accumulate and burn, thus avoiding detonation and achieving quiet ignition, ensuring the occurrence of dangerous accidents such as explosions. This standard gas wall mounted boiler is available from all manufacturers.
