Burners
The burner is the main heat method of the boiler the sole purpose is to burn the gas within the boiler to generate heat to the central heating system or the hot water via heat exchangers. The gas to the burner is supplied via burner injectors and the gas valve, they are directly controlled by the printed circuit board and gas valve. The burner is regulated via the PCB because once preset temperatures are reached for either central heating or hot water less gas is required to be burnt.
