Power Flow Through Ignition Module
The heat relay provides power to ignition module.
Power fl ows to the contacts of the internal relay. If
the module does not energize, the alarm circuit is
energized.
Power fl ows through the coil of the internal relay
to ground for at least the period of the time delay (4
seconds).
The relay stays closed, if all components are
operating, and allows 24 VAC to fl ow through the
system, and to the gas valve.
The blower is now running, the module is sparking,
the gas valve is open and a fl ame is in the burner.
Once a fl ame is in the burner, the fl ame sensor
current has to be above the lockout minimum for the
module. This provides the hold for the relay coil.
Should the fl ame sensor lose fl ame current, the
module will try to relight the burner for the period of
the time delay. If fl ame sensing is not re-established,
the module will lockout.
Ignition Module Functions:
1. Produces high voltage for spark.
2. Senses the fl ame.
3. Provides 24V to gas valve.
4. Provides the Alarm Circuit (24V) to the
High-Effi ciency Gas
