How your stove works
Your King stove 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 pellets up a chute located
at the front/bottom of 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 5-10 minutes from pressing the ON button. As pellets
enter the burn pot 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
by the “HEAT RANGE” setting. In order to maintain combustion of the fuel at a desired rate, the air provided to the 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.
