E. Fuel Specifications
The Absolute43-C Pellet Stove is approved for burning
premium grade pelletized bio-mass fuel.
Hearth & Home Technologies recommends using only fuel
that is certified by the Pellet Fuels Institute (PFI).
It should be noted, however, that higher ash content will
require more frequent cleaning.
The moisture content of pellets must not exceed 8%. Higher
moisture will rob BTU’s and may not burn properly.
Fuel should
not
be stored within the stove installation
clearances or within the space required for cleaning and
ash removal.
Fuel and Fuel Storage
Pellet fuel quality can fluctuate from manufacturer to
manufacturer, and even from bag to bag.
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 and other biomass
Lower Ash Content Material
•
Softwood; pine, fir, etc.
• Materials with lower mineral content
• “Premium” grade pellets
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.
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.
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.
