Abstract

PURPOSE: To perform a positive operation in reference to a desired sequence and provide a safe operation of a sequence intermittent circuit when a component element is troubled by a method wherein a timer circuit and a safe shut-off switch element are combined.
CONSTITUTION: First relay 1K for use in controlling a fan motor M, second relay 2K for use in operating a timer circuit for setting an ignition trial time and operating the fuel feeding valve V1 and the ignitor IG in response to the ignition trial signal from the timer circuit, and a safe shut-off switch SSW for use in controlling on-off operatin of safe switch heater SSH are connected to AC power supply 1. The relay 2K is operated only when the heater SSH is not broken, an operating current is fed to the timer circuit for controlling an ignition trial time. If the ignition is not confirmed within a period in which the operation current is fed, the heater SSH is heated so as to provide a positive turning off of the safe shut-off switch SSW.
