Operating Instructions
A. Fuel Size And Material
1. Wood Pellets
Fuel pellets are made from sawdust or wood by-products. If the
source material is hardwood, they can have a higher mineral
content, creating more ash. Fuels containing bark will also have
higher ash content. Minerals and other non-combustible materials
such as sand will turn into a hard, glass-like substance called
a clinker when heated to the extreme temperatures our firepot
reaches. This is what forms clinkers in the bottom of the firepot.
Trees from different areas will vary in mineral content. That is
why some fuels produce more clinkers than others. Pellets are
manufactured in either 1/4 inch or 5/16 inch (6-8mm) diameter and
should be no more than 1-1/2 inches (38mm) in length. Pellet
lengths may even vary by lot from the same manufacturer which
is why the feed rate may need to be adjusted occasionally. If you
burn pellets longer than 1-1/2 inches (38mm) you may have
an inconsistent fuel feed rate and/or missed ignitions.
Pellet fuel quality can greatly fluctuate. We recommend using
premium grade fuel with ash content less than 1%. Even in some
fuel labeled “premium” ash content can vary from bag to bag
and possibly exceed 1%. High ash fuel, or lack of maintenance,
can cause the firepot to fill up and thus create a potential for
smoking, sooting and possible hopper fires.
Always burn dry fuel. Burning fuel with high moisture content
takes heat from the fuel and tends to cool the appliance,
robbing heat from your home. Damp pellet fuel can clog the
feed system.
We recommend that you buy fuel in multi-ton lots whenever
possible. Buying large quantities of fuel at once will greatly
reduce the number of times the feed adjustments will need to
be made. However, we do recommend trying various brands
before purchasing multi-ton lots to ensure your satisfaction.
2. Shelled Field Corn
Shelled field corn can be an efficient and economical fuel. We
recommend using a 50-50 blend of corn and wood pellets. The
only change in operation; 1) the feed rate may require a slight
adjustment and 2) firepot will require more frequent cleanings.
The BTU output
varies slightly compared to pellets, depending
on the quality of the corn used. In cases where it is acceptable
for the appliance to run full time, 100% corn will work after the
fire has been started using wood pellets.
B. General Operating Information
1. Thermostat Calls For Heat
The appliance is like most modern furnaces; when the thermostat
calls for heat, your appliance will automatically light and deliver
heat. When the room is up to temperature and the thermostat
is satisfied, the red call light will shut off and the appliance will
shut down. The red call light is located behind the left access
panel.

2. Heat Output Controls
This appliance is equipped with a heat output control switch that
has three settings or burn rates; low, medium and high. The
appliance will turn on and off as the thermostat demands. When
the thermostat calls for heat, the appliance will always start up
on High. After burning approximately 4 minutes, the appliance
will then burn at the rate at which it was originally set. If the
appliance is set at one of the lower settings, it will run quieter
but takes longer to heat up an area than if it were set at a higher
burn rate. Regardless of the burn rate, when the area is warm
enough to satisfy the thermostat, the appliance will shut off.
WARNING
Do NOT store flammable materials in the appliance’s
vicinity.
Do NOT use gasoline, lantern fuel, kerosene, charcoal
lighter fluid or similar liquids to start or “freshen up” a fire in
this heater.
Keep all such liquids well away from the heater while it is in
use.
Combustible materials may ignite.
Fire Risk.
Keep combustible materials, gasoline and other
flammable vapors and liquids clear of appliance.
WARNING
High ash fuels, or lack of maintenance, can
cause the firepot to fill with ash and clinker. If the
firepot fills to the top, immediately shut down the
appliance and clean.
Failure to do so could result in smoking, sooting
and possible hoper fires.
Fire Risk.
