LIGHTING AND SHUTDOWN INSTRUCTIONS
1. Turn on the gas and electrical supply. Rotate the gas valve knob counter-clockwise
2. 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.
6. To permanently shut down the heater, rotate the gas valve knob clockwise
off the gas and electrical supply.
