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
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
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 wood pellets, the only ingredient listed should be
wood ber or sawdust.
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 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 mainte-
nance.
“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 try-
ing different brands prior to purchasing multi-ton lots,
to ensure your satisfaction.
CAUTION! Tested and approved for use with wood
pellets ONLY. Burning of any other fuel will void your
warranty.
When changing from “Premium” grade pellets to a
“Standard” or “Economy” grade fuel, the FEED AD-
JUSTER 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.
Do not store fuel within the specied clearance ar-
eas, or in a location that will interfere with routine
cleaning and maintenance procedures.
