ABSTRACT:
There is disclosed a control system for ignition and operation of a combustible gas burner for heating appliances. The control system is intended for use with fuel burners having interrupted or discontinuous pilot burner operation. The control system utilizes the characteristic of a thermomechanical flame sensor such as a diastat, thermocouple, or bi-metallic strip to control the cycling of the system in the event of extinguishing of the burner flame by momentary gas or electrical interruption or air drafts.
