2. The On/Off button (2) turns the Furnace On and Off. It will also reset the board after
the board has sensed a problem and is flashing a Diagnostic code.
3. The auger button (3) will allow the customer to manually auger fuel into the burn pot
on start up when needed. This is particularly helpful in priming the Auger Tube when it is
empty.
4. The Draft Trim button (4) allows for adjusting the Exhaust fan voltage on Heat Level
1 only. Push the button and the all of the LED Lights in the light bar will flash once. This
decreases the voltage approximately 5 volts below the default setting. Push the button a
second time and all of the LED Lights in the light bar will flash twice. This increases the
voltage approximately 5 volts above the default setting. Pushing the button a 3
rd
time will
reset the voltage to the default setting. This adjustment is available to fine tune the #1
Heat Level draft setting. This would only be used in the case the furnace was hooked up
to a tall Vertical Chimney (to decrease the draft if needed) or if it was connected to a
Chimney with a long Horizontal run (to increase the draft if needed).
5. The Feed Trim button (5) will allow the Fuel feed rate to be adjusted on Heat Level 1
only. Heat Level 1 should be seen as the Pilot setting of the furnace, when operating on a
Thermostat. Pushing the Feed Trim button (5) will switch between the different
adjustments. Heat Level one can be adjusted in the following ways:
a.
The first LED only indicates the Normal #1 setting. (2.5 second on time). This is
the highest Pilot setting and may be used when heating a larger size home.
b.
The first and fourth LED lights indicate the #1
Low
setting. (2.0 second on time)
This is the medium Pilot setting and may be used when heating a medium size
home where less heat is needed when the unit is running in pilot mode.
c.
The first and fifth LED lights indicate the #1
High
setting. (1.50 second on time)
This is the lowest Pilot setting and may be used when heating a small size home
where minimal heat is needed when the unit is running in pilot mode.
The adjustments described in points 4 and 5 remain in effect as long as the unit is
plugged in. If the unit gets unplugged or if there is a power failure the settings are
lost and the adjustments would need to be reset.
Pre-Lighting Instructions
When lighting your Furnace for the first time, or any time you have run out of fuel, fill
the hopper. The auger tube will be empty and it helps to hold the “Auger Button” in until
you hear fuel drop into the burn pot. Fuel is fed from the hopper to the burn pot by a high
torque motor that is capable of doing SERIOUS harm to fingers. Keep fingers and other
objects away from the auger.
