9. Test Fire Procedure
Test Firing Deluxe Burner Control
1. Turn ON power and fuel to the fan and heater. Set the controlling thermostat to call for heat.
2. Start fan and move heater switch to the “ON” position.
a. The “FAN ON” indicator light on the board should now be lit.
b. If light is not ON, confirm 120V at terminals 19 and 20. If no power exists, check for power at
the fuse in the fan control box and all safety high-limit switches. Make the needed repairs to
restore power to the terminals 19 and 20.
c. If power exists at terminals 19 and 20, be sure the circuit between 17 and 18 for the air switch
is closed.
3. With the “FAN ON” indicator lit, the troubleshooting lights 1 through 5 should be ON at the end of a
20 second purge cycle. The “IGNITOR ON” indicator will now light.
4. Heater should ignite, and “FLAME PRESENT” indicator should be lit. If flame is present and light not
ON. Adjust sensor into flame until light is ON when flame is burning. It may be necessary to adjust
sensor after changing gas pressure settings.
5. If heater does not light, follow the troubleshooting lights on the wiring schematic decal and correct
faults. Be aware that light #1 relates to the fuse on the board and not the fuse in the fan control box.
If the fuse in the fan box is blown, no lights on the board will be ON.
6. Cycle the controlling thermostat to ensure the heater responds to the call for heat. If the unit is
HIGH-LOW fire, the #6 light will indicate during high-fire.
7. Heater is now ready for normal operation. Set the desired temperature on the thermostat and check
fuel pressure settings.
