Fuel and Fuel Storage
Pelletfuelqualitycanuctuatefrommanufacturerto
manufacturer, and even from bag to bag.
Hearth & Home Technologies recommends using only
fuelthatiscertiedbythePelletFuelsInstitute(PFI).
Fuel Material
• Made from sawdust and/or other wood by-products
• Shelledeld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,r,etc.
• Materials with lower mineral content
• "Premium" grade pellets
Shelledeld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nesandcobremnantsmay
cause feed system jams or blockage
CAUTION! Do not burn fuel that contains an
additive; (such as soybean oil)
• Maycausehopperre
• Damage to product may result
Read the list of ingredients on the packaging. If you are
buyingeldcorn,theonlyingredientlistedshouldbe
eld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
warranty
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
appliance thus, robbing heat from your home. Damp
pellet fuel could turn back into sawdust which does not
owproperlythroughthefeedsystem.
Size
• 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
Performance
• Higher ash content requires more frequent
maintenance.
• "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.
We recommend that you buy fuel in multi-ton lots
whenever possible. However, we do recommend trying
different brands prior to purchasing multi-ton lots, to
ensure your satisfaction.
CAUTION! Attempting to burn fuels such as charcoal
has the potential of generating Carbon Monoxide which
is DEADLY. Never burn fuels other than those listed on
the appliance safety label.
When changing from wood pellets to a corn/pellet
mixture, the FEED ADJUSTER will likely need adjusted
to a lower setting. When under maximum demand,
ensure there is no unburned fuel being pushed into the
ash pan.
Storage
• 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speciedclearance
areas, or in a location that will interfere with routine
cleaning and maintenance procedures.
CAUTION
Tested and approved for use with wood pellets and a
mixtureofshelledeldcornandwoodpellets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.
