    FUEL REQUIREMENTS 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.

    BURNER LIGHTING NOTE: If the burner has been used, all leftover ash and clinkers must be thoroughly removed from the burner pot before following the lighting instructions. **IMPORTANT** On the initial lighting of the furnace, add approximately 2-3 cups of fuel to the hopper. As the fuel feeds into the auger, add only small amounts until the fire is established and the feeding system is working properly.

    Summary of Settings & Operation Draft Adjustment of the chimney draft controls the rate of burn and has an effect during High and Low fire operation. Chimney draft must be set between 0.02 – 0.04 inches water column draft during High fire. The use of a second automatic barometric damper may be necessary on some installations to insure the precise draft control.

Allow the furnace to run for 24 hours, then evaluate heat delivery to the space, the level of fuel in the burn pot, and visible emissions before making adjustments to the combustion air and/or Variable BTU timer. Adjust the Variable BTU timer and combustion air damper so that the space is being adequately heated while at the lowest Variable BTU Timer setting that keeps the fuel level in the burn pot between halfway and completely full and the combustion air damper open the least amount that produces no visible emissions from the vent.
