摘要：A safety circuit , which compulsorily closes an on-off valve for supplying a gas toa burner when a microcomputer for performing a combustion control is in an abnormalcondition, does not operate unless abnormality occurs to the microcomputer , andtherefore even when the safety circuit is out of order, an ignition operation is performed
as it is. A transistor is not turned off until a fixed time elapses from a start of an ignitionsequence in the safety circuit , but the fixed time is shortened by a timer accelerationcircuit , and if the transistor is turned off by a transistor being turned on, the safety circuitis determined as normal, so that the normal ignition sequence is executed thereafter.
