Abstract

PURPOSE: To make automatic ignition by operating an igniter with a pilot valve opened by operating a relay during trial time while an output transistor is on.
CONSTITUTION: A power supply switch SW is turned on, a condenser C1 is charged through the medium of the constantly-closed contact XH2 of a relay XH and a resistor R9, and PUT and an output transistor Tr2 turn on. After the elapse of ignition stand-by time, a relay XP operates to close a constantly-open contact XP. Consequently, a pilot valve PV opens and an igniter IG actuates to make ignition. Ignition operation time is called trial time. When ignition is made during said trial time and flame is detected by a flame detecting circuit, the output of an operational amplifier A becomes H. Therefore, the current having flown in a constantly-open contact SP3 and a diode D2 flows to the base of a transistor Tr3 to turn on said transistor Tr3. Then, an output transistor Tr1 turns on and a relay XF operates to open a constantly-closed contact XF2 so that a main valve is opened.
