The abnormal flame sensing controller is configured in the manner that the abnormal flame sensing signal for the interior of a combustion chamber in a frame rod frame sensing manner is supplied to the input(IN) of a combustion safety controller(P.T.R). Then, the abnormal flame sensed signal passes through resistors(R10,R12), a transistor(Q3) and a diode(D3) to operate a transistor(Q5) and a relay(RY-1), thereby driving a blasting fan(FAN). On the other hand, the flame sensed signal passes through a diode(D5) to operate a transistor(Q6) and a relay(RY-2), thereby driving a pump(PUMP).
