A. Ignition Control
The ignition control is an electronic circuit board
that starts the fan motor, and monitors burner flame
presence through the ignitor and earth ground. (A
good, secure earth ground is required for continued
operation. If the earth ground is missing or poorly
connected, the ignition control will not be able to
prove flame, and it will eventually shut the heater
down)
Refer to the following and Fig. 7 to understand the
ignition control’s terminal designators when doing
voltage checks on the ignition control.

Diagnostic light connection
MV:
120 VAC from ignition control to gas solenoid

The relay then sends the power to the motor.

control.
