DAILY OPERATION
The hopper and furnace top will be hot during operation; therefore, you should always use some type of
hand protection when refueling your furnace.
Never place your hand near the auger while the furnace is in operation.
In the event of a power outage, the furnace WILL NOT function. It is very important that unit be vented properly, as the
natural draft is needed to clear the smoke from the furnace during a power outage. If the unit was “ON” when the power
outage occurred, one of the following will take place when power is restored:
If the furnace is still warm, it will resume feeding fuel and continue to operate normally. If the fire has gone out, you
will have to press the “OFF” button and then the “ON” button again to begin a new start-up sequence.
If the furnace has cooled-off, it will reset to its “OFF” condition. At this point, you may press the “ON” button to
begin a new start-up sequence.
NOTE: The unit will also shut down in the event of an draft fan failure; if this is the case, the unit will not re-start and you
must contact Customer Service at (800) 750-2723.
SAFETY AND CONVENIENCE FEATURES
Your American Harvest incorporates a safety pressure switch that helps ensure that everything is in proper working
order before feeding fuel to the burn pot. Because the furnace works using an induced draft pressure, the furnace will
not continue to operate if the viewing door is left open; or if the draft fan fails or the exhaust system is blocked.
The temperature limit control will prevent your furnace from operating at abnormally high temperatures. Should the
furnace temperature begin to approach the factory pre-set limit, the temperature limit control will automatically slow
down the auger feed rate until the temperature returns to a normal condition. Both room air fans will operate at full
speed also until the furnace returns to normal operating temperatures.
If your furnace continues to cut back because it is reaching the temperature limits, reduce the “heat setting” to the next
lower setting.

Failure to clean and maintain this unit as indicated can result in poor performance and safety hazards.
Unplug your stove’s electrical cord prior to removing the back panel or opening the exhaust system for any
inspection, cleaning, or maintenance work.
Never perform any inspections, cleaning, or maintenance on a hot furnace.
Do not operate furnace with broken glass , leakage of flue gas may result.
EXHAUST SYSTEM
The by products of combustion contain small particles of fly ash. Fly ash will collect in the exhaust venting system and
restrict the flow of flue gases. Incomplete combustion, such as during startup, shutdown, or incorrect operation of the
furnace will lead to soot formation which will collect in the exhaust system. Therefore, it is important that the exhaust
system be inspected and cleaned at least monthly during the burning season.
Check the clean out tees periodically to determine the required cleaning schedule. 3 or 4-inch chimney brushes are
available for chimney cleaning. If the exhaust system or outside air pipes have screens on them, frequently clean the
screen. A plugged screen will shut off combustion air and cause a fire to die or burn poorly.
