Abstract
A combination control for main and pilot burners of gas burner apparatus wherein a thermostatically controlled redundant simultaneously controls the supply of gas to pilot burner and main burner gas outlets. A pilot flow passage has a first branch passageway which supplies a restricted low pilot supply of gas independently of the redundant valve for producing a pilot burner flame of a small standby size when the redundant valve is closed. The pilot flow passage further includes a second branch passageway communicating with the redundant valve for supplying an increased high pilot supply of gas to produce a pilot flame of a larger ignition size when the redundant valve is open. A check valve in the second branch passageway blocks gas flow therethrough from the first branch passageway when the redundant valve is closed.
