ABSTRACT:
A control circuit for use with spark ignition system disposed in a gas burner comprising a high voltage pulse circuit for developing the spark which is gated by a flame sensor. That same flame sensor also controls a timing and latch circuit connected to initially open the gas flow to the burner and to close such gas flow if burning is not established within a predetermined interval of time. The timing and latch circuit also includes components which after an unsuccessful start-up preclude further starting cycles until manual intervention takes place and control all failure modes to a shut-down condition.
