Operation and Maintenance
of the
Auburn corn Stove
SAVE THIS OPERATIONS AND
MAINTENANCE MANUAL
CAUTION: Operate this unit only with the fuel hopper lid closed. Failure to do so may result in
emission of products of combustion from the hopper under certain conditions. Maintain hopper
seal in good condition.
INSTALLATION
Proper installation is essential for safety,
effective operation, warranty coverage,
insurance requirements and to meet local
building codes. Installation requirements are
described in the Installation Manual included
with your new stove.
PREVENTING CHIMNEY PROBLEMS
When burning corn care should be taken in
how the venting system is installed. To burn
corn the moisture content should be 15% or
less. This is much higher that the moisture
content of wood pellets and can result in
condensation forming in the venting system
in certain installations. The chimney system
should stay within the warm envelope of the
house as much as possible. Only penetrate
the exterior of the home where the exhaust
system will terminate. Remember
condensation from a corn stove is
detrimental to the venting system. Only
buy venting systems that are warranted
when burning corn.
The chimney and chimney connector should
be inspected at least once every two months
during the heating season to prevent the
system from getting plugged with Fly ash.
Clean the exhaust system if needed. Use of
an appropriately sized chimney brush or the
Services of a Professional chimney sweep are
recommended.
SHELLED CORN
SATISFACTORY PERFORMANCE
Shelled corn must be 15% or less moisture
content. The keys to satisfactory performance
are: proper operation of the stove, diligent
maintenance and burning only dry, clean, quality
corn. Corn dust must be screened prior to using.
NOTE: Corn with excessive grain dust must be
screened, by sifting with 3/16" mesh screening.
Large pieces of cob may plug the auger.
Clinkers and ash are a by-product of burning corn
and are not caused by your stove. Stove performance
can be quickly and severely reduced if poor quality
corn is used. Contact your dealer for more information on where to get high quality corn to burn in
your new corn stove.
Store corn in a tight container use other methods to
ensure they do not become rain soaked or absorb
moisture from damp or wet floors. This will also
prevent rodents from becoming a problem. Do not
store corn within stove installation clearances or
within the space required for clinker removal.
The stove is not warranted against damage caused by
poor quality corn, incorrect operation, poor
maintenance or incorrect installation.

Operation and maintenance
OPERATING INSTRUCTIONS
A different type of heater. The corn stove is
neither a cordwood stove nor a furnace. Its
operation and maintenance differ from the traditional wood stove. FOLLOW THESE
OPERATING INSTRUCTIONS EXACTLY AS
STATED TO ENSURE SAFE AND RELIABLE
OPERATION.
1. Carefully read this “Operation and Mainte-
nance” manual in its entirety BEFORE lighting
your stove for the first time.
2. Obtain final inspection and approval of
installation from local building officials.
3. Carefully clean all marks off the gold plated
parts before the first fire is lighted. Use a soft
cloth and a “Windex” type cleaner. Caution:
Never use an abrasive cleaner on any plated or
painted parts of the stove.
4. Have your dealer demonstrate all the opera-
tional and maintenance steps necessary for proper
use of the stove. Sign and return the warranty
card, to the address listed on the back page.
5. Some odors may be given off during the first
few hours of burning during initial break-in.
These odors are normal and not harmful.
However, ventilating the room until the odors
disappear is recommended.
6. The stove will become HOT while in
operation. Keep children, clothing and furniture
away from all stove surfaces.
WARNING: Direct contact with the stove
while operating may cause skin burns.
7. To avoid the possibility of smoke and/or sparks
entering the room always keep firebox and ash
pan doors closed whenever the stove is operating.
8. A certain amount of carbon monoxide may be
produced within the stove as a by-product of
combustion. All exhaust vent connections must
be sealed with RTV silicone to assure a gas tight
seal. Any leaks into a confined area caused by
faulty installation or improper operation of the
stove could produce dizziness, nausea and in
extreme cases, death.
9. An outside source of combustion air is strongly
recommended and is required on all mobile home
installations. If room air is used to supply
combustion air, room air starvation, operation of
exhaust fans and icing of air vents can adversely
affect proper stove operation.
10. Smoke detectors, installed in the same general
area as the stove, may be activated if the stove door
is left open and smoke is allowed to enter the area.
Combustion air damper.
This is one of the most important areas of setting up
your stove to burn corn. (See Figure 1 on page 4)
Your stove is equipped with an air inlet damper. 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 s small adjustment during
the break in period. To know if the damper needs to
be adjusted you should learn to recognize how the
corn burns in 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 is 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. If you notice a
difference in the operation of the stove, check to see
if the stove needs cleaning or if the moisture content
of your corn is too high. Break-in requires the
burning of 15 bags of corn or continuous burn for
two weeks. If you experience problems adjusting
the stove after the break-in period contact your
dealer.
For instructions on adjusting the damper see
“Damper Adjustment on page 5.

Operation and maintenance
Pre-Lighting Instructions
When lighting your stove for the first time or any
time you have run out of corn you will need to fill
the hopper with corn. Corn is fed from the hopper
to the burn pot by an auger. A high torque motor
that is capable of doing SERIOUS harm to
fingers drives the auger. Keep fingers and other
objects away from the auger.
WARNING: The auger can start at any time
while the stove is running
CAUTION: The coal rake must be pulled out
and the slide bottom pushed in to operate the
stove. (See stove layout on page 1)
WARNING: The fire door and ash pan doors
must be in the latched position during normal
operation.

also acts as the toggle switch to reset the board after
the board switches to Diagnostic mode.
3. The auger button (3) will allow the customer to
manually auger corn into the burn pot on start up
when needed.
4. The fan button (4) allows for adjusting the
Exhaust fan voltage on level 1 only. Push the button
and the LEDs flash once to decrease the voltage 5
volts. Push the button a second time and the LEDs
flash twice to decrease the voltage another 5 volts.
Pushing the button a 3
rd
time will reset the voltage to
the normal setting. This adjustment is only to be
used under rare circumstances when there is a
problem with over drafting chimneys and the stove
is going out on the #1 setting because of too much
draft.
