St. Croix SCR Installation & Operation Manual page 42

When burning corn, wheat, rye & Distiller's Grain the burn pot should be
"BALANCED". This means the fuel that is being augered into the burn pot rapidly turns
into glowing coals. If you see a lot of unburned fuel in the pot, an adjustment may be
needed. In an unbalanced pot, the corn, wheat or rye will quickly stick together and
prevent the proper flow of combustion air. The pot will overload and the fire will go out.
When burning pellets make sure to check for the formation of creosote in the unit and
venting system. Constantly running the Stove on a low setting with too much combustion
air may cause creosote to form. Burn pot temperatures can be "too cool" when burning
pellets 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 Stove, first check to see if the Stove needs
cleaning then check to see if there has been 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.
If you experience problems adjusting the Stove 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 Stove 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.
Additional draft adjustments can be made using the Draft trim feature built into the
control board. Read point 4a on page 37 and read the "Frequently Asked Questions" in
the back of the manual.
Terminology used when burning Corn, Wheat, Rye or Distiller's Grain
1. Balanced burn pot. This means the corn rapidly turns into red-hot coals once it is
in the burn pot.
2. Lag time. This is the time it takes for the corn to start burning and the burn pot to
become balanced. Corn will tend to stick together in a clump in the burn pot if the
corn feeds in faster than it's burning.
