Abstract
An oscillator utilizing a negative resistance light emitting semiconductor diode is connected in series with voltage booster means which in turn provides a high voltage to electrodes of a gas igniter. Discharge of the gas between the electrodes occurs with the aid of the high voltage derived from the voltage booster means to thereby effect an ignition of the gas. Light emission from the diode in the absence of gas ignition is indicative of a deficiency in the supply of gas, while the absence of light emission in the absence of gas ignition is indicative of a deficiency in the operation of the oscillator circuit.
