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
•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 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 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 warranty
Clinkers
Minerals and other
Trees from different areas will vary in mineral content. For this reason, some fuels will produce more clinkers than others.
Moisture
.125Always 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
•Length should be no more than
•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
We recommend that you buy fuel in
CAUTION! Attempting to burn fuels such as charcoal has the potential of generating Carbon Monoxide which is DEADLY. Never burn fuels other than those listed on the appliance safety label.
When changing from wood pellets to a corn/pellet mixture, 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.
•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.
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.
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.
