Combustion Air Damper
Figure 3
Your stove is equipped with an air inlet
damper. (See Figure 3) This is one of the most
important areas of setting up your stove to
burn corn.
Adjusting the Damper may take a little time and
patience, but only needs to be done once. After
the damper has been adjusted for the unique
installation in your home the control board will
do the rest.
The purpose of this damper is to adjust
combustion airflow to match the characteristic of
each specific air inlet and chimney configuration.
The damper is preset at the factory with a
setscrew. The damper will most likely only need
small adjustments during the break in period. To
know if the damper needs to be adjusted you should
learn to recognize how corn burns in the St. Croix
corn burning system. The burn pot should be
“BALANCED”. What this means is the corn that is
being augered into the burn pot rapidly turns into
glowing coals. If you see a lot of unburned corn in
the pot an adjustment may be needed. In an
unbalanced pot the corn will quickly stick together
and prevent the proper flow of combustion air. The
pot will overload and the fire will go out. 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. Adjusting the damper should be done
during Break-in. This requires the burning of 15
bags of corn or continuous burn for two weeks.

If you experience problems adjusting the stove during
the Break-In Period, contact your dealer.
Figure 4 above may be used to gage the approximate
damper setting when making an adjustment. Some
chimney systems will fall outside the norm, for example,
a chimney with excessive draft or one with a long
horizontal run. In dealing with technical support, the
terminology listed in figure 4 may be used to clarify
where your damper needs to be set.
Terminology used in the Damper Adjustment
1. Balanced burn pot. This means the corn
rapidly turns into red-hot coals once it is in the
burn pot.
