The Worcester Bosch pilot burner is a naked 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 conjunction with the rest of the pilot assembly as well as the printed circuit board to ensure that all of the injected gas is ignited safely and efficiently.
