1.
Turn on the gas and electrical supply. Rotate the gas valve knob counter-clockwise
to the “ON” position.

Set the thermostat to call for heat. The blower motor will energize.
3.
Ignition should occur after the 15-second pre-purge.
4.
If the burner fails to light, or flame is not detected during the first trial for ignition (a period of approximately
15 seconds) the gas valve is de-energized and the control goes through an inter-purge delay of
approximately 60 seconds before another ignition attempt. The control will attempt two additional ignition
trials before going into lockout, and the valve relay will be de-energized immediately. The blower will be
turned off following a post-purge period of approximately 30 seconds.
5.
If the heater does not light, manually reset the thermostat or shut off power completely for 5 minutes before
attempting to relight.

To permanently shut down the heater, rotate the gas valve knob clockwise
to the “OFF” position and turn
