FLAME SENSOR CURRENT CHECK
SERVICE CHECKS
Flame current is the current which passes through the flame from the sensor to ground. The minimum flame current necessary to
keep the system from lockout is 0.7 microamps. To measure flame current, connect an analog DC microammeter to the FC1/FC2
terminals per figure. Meter should read 0.7 µA or higher. If meter reads below “0” on scale, meter leads are reversed. Disconnect
power and reconnect meter leads for proper polarity.
