The Potterton pilot burner is a flame within the unit that is used to ignite the gas that is coming into the main burner. When the appliance is turned on, the gas valve releases gas into the burner, which is then ignited by the pilot flame. The pilot flame works in tandem with the printed circuit board and the rest of the pilot assembly to ensure that all of the injected gas is ignited efficiently and safely.
