Abstract

PURPOSE: To prevent the overheat of and the gas leakage of a combustion control device by enabling direct inspection of the conduction and the nonconduction of an important transistor under an ignition combustion control and stopping the ignition combustion at the time of abnormal state.
CONSTITUTION: When a power switch SW is closed, a fan motor FM is started, a flame detecting circuit 2, the first and second inspecting circuits 3, 4, a prepurge timer circuit 5 and a forcible ignition circuit 6 are operated by the output of a rectifier DC1. The first inspecting circuit 3 inspects the nonconduction of an FET(F1) of the flame detecting circuit 2 during the prepurge operation, and the second inspecting circuit 4 inspects the conductions of transistors Tr4, Tr3 of the main drive circuit 7 and the ignition drive circuit 8 during the prepurge operation. When both are normal, high potential output is produced. When a malfunction of any of the FET, Tr3, Tr4 is detected by the inspecting circuits 3, 4, a control circuit 1 is made inoperation to inhibit the ingition combustion.
