ABSTRACT:
A system including a circuit for igniting or reigniting a pilot burner in a gas fired device each time heat is called for by a thermostat or otherwise. The main burner is ignited by the ignited pilot upon detection of pilot ignition. A sequencing interlock is provided for trial ignition over a limited period of time. An output of a main valve control acting through the sequencing interlock causes sustained actuation of a pilot valve control if the main valve control is actuated.
