St. Croix SCF-Revolution Installation & Operation Manual page 35

When burning pellets make sure to check for the formation of creosote in the unit and
venting system. Constantly running the Furnace on a low setting with too much
combustion air may cause creosote to form. Burn pot temperatures can be "too cool"
when burning on low with too much draft. Once the damper is adjusted for your
installation, it should not be necessary to make any further adjustments to the damper.
The combustion air is automatically increased every time the feed rate is advanced on the
control board. If you notice a difference in the operation of the Furnace, first check to see
if the Furnace needs cleaning. Then check to see if there is a change in the fuel you are
burning. The moisture content of your corn may be too high or the quality of the pellets
you are burning may have changed. Break-in requires the burning of 15 bushel of corn or
15 bags of pellets or a continuous burn for two weeks. The setscrew is a useful tool in
making adjustments to the Air Intake damper Adjust the damper by turning the screw a
.
1/2 turn clockwise and place the damper blade against the screw. Wait 10 minutes to
allow the burn to adjust to the new setting. Making too many changes in a short period of
time will not allow for an accurate adjustment.
If you experience problems adjusting the Furnace during the Break-In Period,
contact your dealer. Some chimney systems will fall outside the norm, for example, a
chimney with excessive draft or one with a long horizontal run.
Damper Adjustment Procedure.
Once the Furnace has been lit for the first time, the damper will need to be adjusted. The
process is different for Corn than Pellets. This may take some time, so please be patient
during this process. This Damper Adjustment process only needs to be done once. After
the damper has been adjusted to the unique installation in your home, the control board
will do the rest.
As was stated earlier there is a setscrew in the damper and the damper has been preset at
the factory. This setting will most likely work for 90 % of the most common installations.
Long horizontal runs might need the damper opened. Tall vertical runs might need the
damper to be closed a little, etc. To adjust the damper, use the setscrew to make the
adjustments. To make an adjustment turn the screw ½ turn clockwise to open the damper
or ½ turn counter clockwise to close the damper. Turning the setscrew counterclockwise
will not move the damper; so remember to use the damper handle to bring the damper up
to the screw. After making an adjustment wait at least 15 minutes to see how the burn pot
reacts to the change.
Terminology used when burning Corn, Wheat, Rye of Distiller's Grain
1. Balanced burn pot. This means the corn rapidly turns into red-hot coals once it is
in the burn pot.
