ABSTRACT OF THE DISCLOSURE A self-contained electric igniter in which the ignition pilot is actuated by a rechargeable battery to supply energy for the spark provided by an igniter. All energy for opening the valve of the main gas valve is supplied by a millivolt thermopile generator which together with additional thermopiles charges the battery. A diode is located in the battery charging line to prevent reverse flow of current from the battery to the thermopiles. The system has a safety valve which closes off flow of gas into the system in the event the pilot burner fails to ignite and a flame switch which closes off the flow of current to the main gas valve and consequent flow of gas into the system in the event the pilot burner is extinguished. It also has a damper control system which is closed when the system is shut off to reduce stand-by losses and conserve energy.
