Understanding your stove

How your stove works
Your Forester stove utilizes a vertical auger fuel feed system that is operated by a microprocessor controlled digital
circuit board. The digital circuit board allows the vertical 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 pellets up a chute
located in the hopper which in turn falls through another chute into the burnpot. Your stove is equipped with an automatic
ignition system that should ignite the fuel within 3 - 5 minutes from pressing the button. As pellets enter the burnpot
and ignite, outside air is drawn across the fuel and heated during the combustion process which is then pulled through
the heat exchanger by the exhaust motor or draft fan. As the stove heats up, room air is circulated around the heat
exchanger by means of a room air blower, distributing warm air into the room.
The amount of heat produced by the stove is proportional to the rate of the fuel that is burned, and this rate is controlled
. In order to maintain combustion of the fuel at a desired rate, the air provided to the
by the Fuel Control button
burn chamber by the exhaust or draft fan must be maintained precisely. Too little air will result in a flame that is non-
energetic or lazy. If the fuel continues to flow with too little air for long enough, the burn pot will fill with too much fuel and
the fire will smother out. To much air will result in a flame that is overactive or aggressive. The flame in this situation is
typically very blue at the bottom and resembles a blow torch. If this situation continues, the fuel in the burn pot will be
consumed and the fire will go out.
Matching the amount of air required for proper combustion to the fuel rate is the primary objective in effectively burning
pellets of various brands and qualities in your stove. The air to fuel ratio can be adjusted to allow almost any fuel quality
to burn effectively by following the procedures detailed in the remainder of this manual.
Because a forced draft pressure is required for the combustion process inside your stove, it is extremely important that
the exhaust system be properly installed and maintained. And, that when operating your stove, you make sure that the
viewing door is properly sealed.
