| description | Since when the microcomputer for controlling combustion is abnormal, the safety device 31 that forcedly close the ON/OFF valve supplying gas to the burner will not be actuated when microcomputer is not abnormal, the ignition operation will be performed even the safety circuit 31 is malfunctioned. To solve this problem, in accordance with the present invention, in the safety circuit, transistor 4 is not OFF from the ignition schedule for a predetermined period of time. If the predetermined period of time is shortened by a timer accelerating circuit 32, and the transistor 4 is in an OFF state because the transistor 2 is ON, the safety circuit is determined to be normal, and then a normal ignition schedule can be performed. |
