ABSTRACT:
A control circuit for a gas appliance includes ignition and hold circuits, the former providing for series energization of the heater of a thermal fuel valve and an electric igniter positioned proximate the appliance burner port area for ignition of the gas fuel and air mixture exiting the same and the latter providing for direct energization of only the igniter to hold or to maintain the appliance at a warm temperature. Moreover, the fuel valve includes an exterior selector mechanism for facile calibration and/or other adjustment for effective valve operation with either of two different gases at respectively different pressures, such as, for example, natural gas and bottled gas.
