Do not operate your furnace with the viewing door open. The auger will not feed fuel under these
circumstances and a safety concern may arise from sparks or fumes entering the room.
A working smoke detector must be installed in the same room as this product.
Hopper Lid must be closed during operation. The auger will not feed fuel if the lid is open.
HOW YOUR FURNACE WORKS
Your Multi-Fuel Furnace utilizes a inclined auger fuel feed system that is operated by a microprocessor controlled digital
circuit board. The digital circuit board allows the inclined auger fuel feed system to run in a timer-based, non-continuous
cycle; this cycling allows the auger to run for a predetermined period of seconds. The auger pushes fuel up a chute
located at the front/bottom of the hopper which in turn falls through another chute into the burnpot . As fuel enters the
burn pot, outside air is drawn across the fuel and heated during the combustion process. This heated combustion air is
then pulled through the heat exchanger by the Draft Fan, where it is used to heat air that is drawn into the heat exchanger
system by the Room Air Fan.
Because a forced draft pressure is required for the combustion process inside your furnace, it is extremely important
that the exhaust system be properly installed and maintained. And, that when operating your furnace, you make sure
that the viewing door is properly sealed.
Your furnace’s heat output can vary from Hi to Low by adjusting the settings on the control panel (located on the lower
left-hand side of the furnace). The “HEAT RANGE” setting will vary the auger systems feed rate (i.e. fuel to combustion
air ratio) and has three settings, low / medium / high. This is indicated by displaying a Hr-1 thru Hr-3 under Heat Range.
Your furnace has two distribution “Room Air” fans. Fan “A” located on the left side of the unit, same side as the (PCB)
Printed Circuit Board, will come on when flue gas temperatures reaches the (POT) Programmable Operating Temperature
(200°F) preset on the control board. During shutdown, Fan “A” will remain on until the operating temperature reaches
the preset temp. 110°F. Fan “B” will come on when plenum temperatures reach the preset (PPT) Programmable
Plenum Temperatures (95°F). The fan will remain on until the plenum temperature drops 5°F below the programmed
duct temp.
Your furnace can run efficiently over extended periods of time and at different heat output levels as long as the air/fuel
mixture is correct and the fuel supply is uninterrupted along with proper cleaning and when maintenance is performed.
DAMPER CONTROL ADJUSTMENT
Your furnace has an adjustable intake damper located behind the Backdraft Assembly just under the Feed Door. This
damper can be adjusted for fine tunning fuels to burn at optimum performance and can help with efficiency when burning
inconsistant fuels. When burning corn, it is suggested that the damper position be on Medium to HI. When burning
wood pellets, it is suggested that the damper position be on low to medium. These conditions will vary with your type of
fuel.
