Abstract

PURPOSE: To prevent occurrence of a dnagerous condition by detecting an off-state of a switch which turns on and turns off a power supply circuit so as to make a controlling circuit inoperative.
CONSTITUTION: A burner 2 is supplied with gas through a proportional electromagnetic valve 6 and a main electromagnetic valve 7 and ignited by an ignition plug 8, which also observes the burning condition of the burner 2. The porportional electromagnetic valve 6 is driven by a drive circuit 9 to open or close and the ignition plug 8 is also driven by the drive circuit 9 to perform electrical discharge and flame detection. The control circuit 11 is adapted to become operative upon the power supply from the power supply circuit 10 and inoperative when a water flow switch 4 is off and one end T of a resistor R2 becomes of an earth level. Accordingly, the off-condition of the water flow switch 4 renders the control circuit 11 to be inoperative, thereby stopping the burning of the burner 2. Thus, a possibility of accident occurrence due to a misoperation can be eliminated.
