D. Fuel Specifications
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 (must be mixed with up to 50% 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
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 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
and up to a 50% mixture of shelled field corn and wood
pellets ONLY. However, for guaranteed automatic lighting
on a corn & pellet blend, we recommend an 80/20 mix
of pellets to corn. Burning of any other fuel will void your
warranty.
When changing from wood pellets to a corn/pellet mixture,
the Feed Limit 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 specified clearance areas,
or in a location that will interfere with routine cleaning
and maintenance procedures.
NOTICE
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.
CAUTION
!
Tested and approved for use with wood pellets ONLY.
Burning of any other fuel will void your warranty.
