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 (See figure 5). 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. (See figure 5) 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. (See figure 2)
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. (See figure 3)
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. (See figure 4)
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.
