Abstract

PURPOSE: To prevent a misoperation of the safety means by a method wherein both ends of an electromotive voltage range generated in a sensor at a normal combustion time of the combustor are set as reference voltages and inputted into a control circuit.
CONSTITUTION: A circuit for controlling a gas supply relay contact 11 and the like for an electromagnetic valve 8 within a gas supply passage 12 is connected to a power source transformer 4. To this circuit, a constant voltage circuit 20 having a first and a second comparator 25 and 28 and the like, a power supply circuit 21, etc. are connected. Reference power sources 46 and 50 of comparators 25 and 28 which receive the electromotive force of the sensor 22 being set to be low at the time of an incomplete combustion are formed to have a voltage lower or higher than a stationary electromotive voltage. When the electromotive voltage of the sensor 22 drops below the reference power source of the comparator 25 or exceeds that of the comparator 28, the electromagnetic valve 8 closes to turn OFF the power supply circuit 21 to turn OFF a alarm circuit 64. Then an alarm lamp 71 emits light and an alarm buzzer 72 starts sounding.
