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
• 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
CAUTION! Do not burn fuel that contains an
additive; (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 wood pellets, the only ingredient listed should
be wood fiber 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
appliance thus, robbing heat from your home. Damp
pellet fuel could turn back into sawdust which does not
flow 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! 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
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.
• Do not store fuel within the specified clearance
areas, or in a location that will interfere with routine
cleaning and maintenance procedures.
CAUTION
Tested and approved for use with 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.
