PURPOSE:To automatically preform reignition to improve the convenience for use in such a manner that an ignition control part actuates an igniter by an output of a going-out detector at the time of igniting a gas. CONSTITUTION:An ignition control part 8 receives a signal from a going-out timer 14 which outputs a signal for a predetermined time after generation of a signal from a going-out detector 9 thereby to actuate an igniter 5 and carries out reigniting operation for a predetermined period of time. In this case, a solenoid valve 2 is continuously opened so that the gas is again burnt with respect to the going-out generated by the temporary dilution of the gas. After the reignition, in a case where the going-out is recognized continuously by an ignition state detector 6 after the lapse of a predetermined period of time, the solenoid valve 2 and an igniter 5 are stopped at that point in time thereby to terminate the combustion operation. Also, in a case where the going-out is detected for a plurality of times, the solenoid valve 2 and the igniter 5 are stopped at that point in time and the combustion operation is terminated. |
