ABSTRACT:
Gas control apparatus to regulate the flow of gas to a plurality of burners is disclosed. The apparatus permits a main gas solenoid valve to be actuated for a pre-determined period of time allowing the burners to be ignited. If the burners are not ignited within the pre-determined period of time, the main gas solenoid valve is deactuated. Even though a main gas solenoid valve is utilized, each burner can be separately ignited by means of a start signal applied thereto. After ignition, the main gas solenoid valve will remain actuated only if a flame is present at the ignited burner and a start signal is applied to the remaining burners.
