Abstract

PURPOSE: To provide a positive ignition by a method wherein a starting of measurement of an ignition trial time set in a timer circuit is performed only with such a condition as a flow rate of air fed into the combustion combustion chamber is set at a minimum value.
CONSTITUTION: In case of succeeding in an ignition, a level at the output terminal of a flame sensor circuit FC is decreased when a flame sensor circuit FC is decreased when a flame is formed within an ignition trial time and even if the ignition trial time is passed, the transistor Q8 is kept conducted, the relay 3K is made nonoperated, the contact point 3K2 is turned off, an operation of the ignition means 6 is terminated, a pilot flame stabilizing time is initiated the relay 1K is deenegized, the contact point 1K2 is turned on, the main burner valve 5 is operated, a constant combustion is performed, the relay 4K is operated again, the contact point 4K1 is changed over and the changed-over condition is kept until a thermal request is made. In case of a failure in the ignition, all the relays 1K to 4K are deenergized to cause each of the contact points in a load driving control circuit 30 to be recovered.
