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 (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, fir, etc.

Materials with lower mineral content

“Premium” grade pellets

Shelled field 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 fines and cob remnants may cause feed system jams or blockage

CAUTION! Do not burn fuel that contains an addi- tive; (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 field corn, the only ingredient listed should be field 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 war- ranty

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 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 main- tenance.

“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 and a mixture of shelled field corn and wood pellets ONLY. Burning of any other fuel will void your warranty.

When changing from wood pellets to a corn/pellet mixture, the FEED ADJUSTER will likely need adjust- ed 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 ar- eas, 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 field corn and wood pel- lets ONLY. Burning of any other fuel will void your warranty.

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.
