8. Are there any adjustments that can be made, through the control board, to the amount of
fuel that is fed into the burnpot?
Answer: There are several ways to adjust the amount of fuel that is
fed into the burnpot. The feedrates can be fine-tuned while the
furnace is in operation by pressing and holding the "Auger Feed"
button down and then either pressing the "Heat Level High" button
to advance the federate higher, or pressing the "Heat Level Low"
button to decrease the feedrate.
There are 5 levels on the control board and they are indicated by
single flash of the LED's. The default setting is the center LED.
This gives 2 adjustments increasing the feedrate (LED's 4 & 5)
and 2 adjustments decreasing the feedrates. (LED's 1 & 2) The ON
time is increased or decreased .25 seconds with each adjustment.
9. Are there any adjustments that can be made, through the control board, to the Combustion
Fan voltages to help adjust the draft?
Answer: The Draft can be adjusted in a similar fashion as mentioned in
the previous example.
The Fan voltages can be fine-tuned while the furnace is in
operation by pressing and holding the "Auger Feed" button down
and then either pressing the "Trim High" button to advance the
voltages higher, or pressing the "Trim Low" button to decrease the
fan voltages.
There are 5 levels on the control board and they are indicated by single
flash of the LED's. The default setting is the center LED. This gives 2
adjustments increasing the voltage (LED's 4 & 5) and 2 adjustments
decreasing the voltage. (LED's 1 & 2) The voltage is increased or
decreased 2.5 volts with each adjustment.
