A system is provided for igniting and monitoring a fuel burning heat source which comprises a thermoelectric safety burner valve, a thermocouple to be heated by a pilot burner, a fuel source feeding fuel to a pilot feed valve and to a main burner feed valve, which in turn are connected to the pilot burner and respectively the main burner. An electric supply source is provided for energizing either an ignition voltage generator or a thermostat simulator. The igniting and monitoring system can be operated electrically or otherwise manually regardless of the state of the electric supply source. A manually operable pilot fuel valve is connected in parallel to the electrically actuated pilot fuel valve and is connected with a switch for disconnecting the electric supply voltage. Thus the heat source can be operated manually in cases where the electrical supply source is not available without impairing the generation of heat.
