Fuel and Fuel Storage
Pellet fuel quality can fluctuate from manufacturer to
manufacturer, and even from bag to bag.
Hearth & Home Technologies recommends using only
fuel that is certified by the Pellet Fuels Institute (PFI).
Fuel Material
• Made from sawdust and/or other wood by-products
• Shelled field corn (when mixed with wood pellets)
• Source material typically determines ash content
Higher Ash Content Material
• Hardwoods with high mineral content
• Bark and leaves as source material
• "Standard" grade pellets, corn and other biomass
Lower Ash Content Material
• Softwood; pine, fir, etc.
• Materials with lower mineral content
• "Premium" grade pellets
Shelled field corn
• Must be 15% moisture content or less
• Must be clean and free of debris
• Must be mixed with wood pellets. (Up to 50%)
• Stalk parts, excessive fines and cob remnants may
cause feed system jams or blockage
CaUTION! Do not burn fuel that contains an addi-
tive; (such as soybean oil)
• May cause hopper fire
• Damage to product may result
Read the list of ingredients on the packaging. If you are
buying field corn, the only ingredient listed should be
field corn.
WaRNINg! Risk of Chemical Poisoning!
Do NOT burn treated seed corn
• Chemical pesticides are harmful or fatal if swallowed
• Burning treated seed corn will void the product war-
ranty
Clinkers
Minerals and other non-combustible materials, like sand,
will turn into a hard glass-like substance when heated.
Trees from different areas will vary in mineral content.
For this reason, some fuels will produce more clinkers
than others.
Moisture
Always burn dry fuel. Burning fuel with high moisture
content takes energy to dry and tends to cool the appli-
ance thus, robbing heat from your home. Damp pellet
fuel could turn back into sawdust which does not flow
properly through the feed system.

We recommend that you buy fuel in multi-ton lots
whenever possible. However, we do recommend try-
ing different brands prior to purchasing multi-ton lots,
to ensure your satisfaction.
CaUTION! Tested and approved for use with wood
pellets and a mixture of shelled field corn and wood
pellets ONLY. Burning of any other fuel will void your
warranty.
When changing from wood pellets to a corn/pellet
mixture, the FEED ADJUSTER will likely need adjust-
ed to a lower setting. When under maximum demand,
ensure there is no unburned fuel being pushed into
the ash pan.

Tested and approved for use with wood pellets

lets ONLY. Burning of any other fuel will void your
warranty.
Hearth & Home Technologies is not responsible for
stove performance or extra maintenance required
as a result of using fuel with higher ash or mineral
content.
Pellets are either 1/4 inch or 5/16 inch (6-8mm) in
diameter
Length should be no more than 1-1/2 inches
(38mm)
Pellet length can vary from lot to lot from the
same manufacturer
Higher ash content requires more frequent main-
tenance.
"Premium" grade pellets will produce the highest
heat output.
Burning pellets longer than 1-1/2 inches (38mm)
can cause inconsistent feeding and/or ignition.
Wood pellets should be left in their original sealed
bag until ready to use, to prevent moisture.
Shelled corn should be stored in a tightly sealed
container to prevent moisture and to deter pests
Do not store fuel within the specified clearance ar-
eas, or in a location that will interfere with routine
cleaning and maintenance procedures.
