ABSTRACT:
A gas burner control system including a main burner and a pilot burner for igniting the main burner wherein the pilot burner is ignited only when the thermostat is calling for heat and gas is permitted to flow to the main burner only after the existence of a pilot burner flame adequate to ignite the main burner has been proven. A pressure actuated switch is effective, following an electrical power interruption or a failure of or an appreciable reduction in gas pressure, to prevent the resumption of gas flow to the main burner until a pilot burner flame adequate to ignite the main burner has been re-established.
