Abstract
A gas burner control system utilizes an electrical resistance igniter to ignite a main burner. Electronic sensing means is located adjacent the burner and adjacent a portion of the igniter where opposite voltage polarity exists between the igniter and sensing means. Current flows from the igniter to the sensing means when the igniter is heated above ignition temperature. Circuit means is responsive to such current flow to de-energize the igniter and enable gas to flow for a timed trial ignition period, the igniter having sufficient mass to remain at or above ignition temperature for the trial ignition period. When ignition occurs, the circuit means is responsive to current flow through burner flame from the sensing means to the burner to maintain gas flow.
