Abstract

PURPOSE: To facilitate the safety confirmation by providing an oscillator in a state indicator and flashing an indication element during ignition and extinction of fire to the burner, and continuously igniting the indication element during the stable combustion.
CONSTITUTION: In a state indication circuit 50 there is provided an oscillator consisting of an operating amplifier 51, a resistor 52, a capacitor 53, resistors 54, 55 and 56, and a capacitor 57 for miscellaneous prevention. A driving circuit consisting of resistors 56 and 59, a transistor 60 and resistors 61 and 62, is connected to the oscillator. The indication element 63 is driven by this driving circuit. When a flame detection circuit 30 detects the ignition of a pilot burner 5, a contact 40 is turned on, and a transistor 60 is also turned on through a resistor 61, the indication element 63 being continuously ignited. In the other state, the indication element assumes a flashing state. Accordingly, it is possible to easily confirm the safety.
