Abstract
A gas burner control system includes a main burner, two electrically controlled valves connected fluidically in series with the burner, an electrical resistance igniter, a temperature responsive switch, and a diode steering circuit for controlling energizing of the valve windings and the igniter. The connected polarities of the diodes in the steering circuit are such that the winding of the first valve is energized by the alternating current power source when the source is of one polarity and the winding of the second valve is energized by the source when the source is of the opposite polarity.
