Abstract

PURPOSE: To improve safety of a combustion device, by suspending the load by virtue of an after purge timer circuit in case of a trouble of a charge/discharge timer circuit which controls the load of a fuel valve and ignition device.
CONSTITUTION: When the output of a charge/discharge circuit 5 becomes logical "O" due to a trouble of the circuit 5, that is, the leak of No.1 and No.2 time constnat circuits 18, 19 or due to a trouble of ligical circuits 20, 22, a load 25 works to actuate an ingition device 55 and a fuel feeder 56. Since the input of an after purge timer circuit 11 is then in a state of logical "O", the output is also "O" even after a time constant circuit 44 discharge, and a load 50 is off and a relay contact 52 is open to suspend a burner motor 54, igniter 55 and fuel feeder 56. This can improve the safety of the combustion device
