ABSTRACT:
A gas burning power supply section 10 for igniting gas includes a secondary battery and a solar battery for charging the secondary battery, and the operating voltage from the power supply section 10 is supplied to a gas ignition circuit 30, a flame detection circuit 50 for detecting the flame after the gas is ignited, and a solenoid valve-controlling timer circuit 60 for controlling the gas supply. A day
ight discrimination circuit 100 is provided in association with the power supply section 10, and the ignition circuit 30, the flame detection circuit 50 and the timer circuit 60 are individually set in operation in accordance with a day
ight discrimination output during the nighttime. In the event the flame of burning gas goes out halfway, the timer circuit 60 operates to perform a trial including reigniting operation, and if the reigniting fails during a trial period, the gas supply is automatically shut off.
