Fuel Requirements - A-Maize-Ing Heat NRP620-10 Owner's Manual

The A-Maize-Ing Heat® furnace is designed to burn premium wood pellets and dry shelled corn.
High moisture content will cause the fire to burn cooler and increase the possibility of creosote
production along with increasing emissions. High ash content will require cleaning of the heat
exchanger more often, decreasing efficiency, and increasing emissions in addition to requiring the ash
pan to be emptied more often. High chlorine content can result in the formation of acidic residue,
which will corrode the heat exchanger and flue pipe. Fuels with high starch or oil content will more
readily form clinkers, which will require additional maintenance to remove, higher ash content, and less
efficient fuel use.
When selecting wood pellets as a fuel, we strongly encourage the use of pellets certified by a third
party testing organization such as The Pellet Fuels Institute, ENplus, or CANplus. Pellets should have
the following characteristics:
(1) Density: Consistent hardness and energy content with a minimum density of 38
pounds/cubic foot;
(2) Dimensions: Maximum length of 1.5 inches and diameter between 0.230 and 0.285 inches
(smaller/shorter pellets will pack into the burn pot restricting combustion air flow, resulting
in less efficient combustion);
(3) Inorganic fines: Less than or equal to 1 percent;
(4) Chlorides: Less than or equal to 300 parts per million by weight;
(5) Ash content: No more than 2 percent.
(6) Contains no demolition or construction waste;
(7) Trace metals: Less than 100 mg/kg; and
(8) None of the prohibited fuels in the "DO NOT BURN" paragraph of this section.
Burning these materials may result in release of toxic fumes or render the heater
DO NOT BURN:
ineffective and cause smoke.
(1) Garbage;
(2) Lawn clippings or yard waste;
(3) Materials containing rubber, including tires;
(4) Materials containing plastic;
(5) Waste petroleum products, paints, or paint thinners, or asphalt products;
(6) Materials containing asbestos;
(7) Construction or demolition debris;
(8) Railroad ties or pressure-treated wood;
(9) Manure or animal remains;
(10) Salt water driftwood or other previously salt water saturated materials;
(11) Unseasoned wood; or
(12) Paper products, cardboard, plywood, or particleboard. The prohibition against burning
these materials does not prohibit the use of fire starters made from paper, cardboard, saw dust,
wax, and similar substances for the purpose of starting a fire in an affected wood heater.
Gelled fire starter approved for use in biomass appliances may be used. Do not use chemicals
or fluids to start the fire.
