SERVICE CHECKS
Flame current passes through the flame from
the sensor to ground. The minimum flame cur-
rent necessary to keep the system from lock-
out is 0.7 microamps. To measure flame cur-
rent, connect an analog DC microammeter to
the FC- FC+ terminals per figure at right.
Meter should read 0.7 µA or higher. If the me-
ter reads below “0” on scale, meter leads are
reversed. Disconnect power and reconnect
meter leads for proper polarity.
