ABSTRACT:
An improved gas burner control system which eliminates the need for a pilot light for operation of a gas burner, including a pair of gapped electrical conductors forming a set of ignition points disposed adjacent to a gas burner, a sensor for detecting the presence of the gas to be burned via the gas burner adjacent to the gas burner, means for electrically coupling the sensor means to a relay, the relay controlling the delivery of electrical current to a second relay, the second relay operable in an alternating fashion, means for electrically interconnecting the points of the alternating relay to the pair of ignition points, means for electrically controlling the flow of gas to the gas burner concurrently with the sensing of the existence of gas flowing out of the gas burner by the gas sensor, the alternating relay being operable upon the detection by the sensor means of the flow of gas from the gas burner, remote means for visually indicating if the electrically controlled valve is open, and means for indicating temperature.
