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 (high fire). 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) CAUTION: The heater must be grounded. Poor grounding will give nuisance lockouts, particularly during
momentary power interruptions.
7) When the thermostat is satisfied with high heat, the heater will switch to low fire.
8) To shut off the heater, rotate the gas valve knob clockwise
manual gas shut off valve supplying the heater and disconnect the electrical supply.
