BURNING SOLID FUELS
Ashes will have to be Removed from the stove periodically. See cleaning procedure. You can minimize cleaning required
and maximize efficiency by maintaining the correct draft settings. See “Draft Setting” further in the manual.
The draft setting on your stove may have to be changed from time to time to accommodate your specific burning conditions.
Proper draft setting will be discussed later in this manual. The point we wish to make here is that your American Harvest
stove, due to the nature of solid fuels, will require brief periodic attention. Please do not expect to light your stove and walk
away from it until you want to shut if off in the spring. A few moments of adjustment and cleaning from time to time is an
important part of burning solid fuels.
The American Harvest stove has been designed to burn shelled corn, wood pellets and other pelletized fuels that meet
Association of Pellet Fuel Industries standards.

BURNING SOLID FUELS continued...
SHELLED CORN (Dry, pref erably corn with 11- 12% moisture content)
•
Corn must contain less than 14% moisture content. Wet corn will rapidly deteriorate stove components, reduce
efficiency and void all warranties.
•
Corn must be clean and free from debris. Never burn corn right from the field. Damage caused by dirty corn is not
covered by the product warranty . Ask f or clean bagged corn only .
•
NEVER BURN SEED CORN IN YOUR STOVE. Seed corn is treated with chemical pesticides that are harmful or fatal if
swallowed, therefore, seed corn is dangerous to have in the house, especially where children can reach it.
•
Store your corn supply in a dry place and keep bags or container sealed to prevent your corn from absorbing excess
moisture. T est the moisture content periodically to maintain the proper dryness.
•
There are many varieties of corn grown around the world. Each variety has unique characteristics including the shape
and size of the kernel. Y our stove will burn more consistently with a small to midsize kernel corn. If the kernel size of
the corn varies greatly or if you switch sources frequently , you will get a less consistent burn, which will require mor e
attention to the draft setting on your stove. Therefore, purchasing corn from the same source will help achieve a more
consistent burn. DO NOT USE CORN WITH A HIGH WAX CONTENT!
WOOD PELLETS
•
As with corn, be consistent in your pellet supplier . P ellets will vary in content and burn characteristics from supplier to
supplier . A consistent supply of pellets will require fewer adjustments to the dr aft of the stove.
•
Check your pellets for foreign objects. Y our stove warranty will not cover damage done to your stov e due to foreign
objects in the fuel supply .
•
Store your pellets in a dry place to prevent them from absorbing excess moisture.
•
T o decrease sawdust buildup, the hopper will need to be vacuumed out after ev ery 6-8 bags of pellets or more often if
the pellets are poor quality . Y ou may have to screen each bag of pellets if sawdust becomes a problem.
•
Wood P ellets vary in size and ash content from less than 1% to 3% or more. Y our stove will burn more efficiently with
small to midsize pellets. Low ash content pellets will allow you to burn the stove longer between cleanings. Only wood
pellets manufactured to the Association of Pellet Fuel Industries (A.P.F.I.) standard for residential pellets fuels are
recommended. Performance will suffer if nonstandard pellets are used. Consult your local American Harvest reseller
for more information on approved wood pellet fuel.
CAUTION: DO NOT PLACE SUCH FUELS WITHIN THE SPACE HEATER’S INSTALLA-
TION CLEARANCES OR WITHIN THE SPACE REQUIRED FOR CHARGING AND ASH
REMOVAL.

GUIDELINES FOR EXHAUST VENTING SYSTEMS DESIGN
It is recommended that only an authorized installer install your pellet/corn stove. The following installation
guidelines must be followed to ensure conformity with both the safety listing of this stove and to local building codes.
INSTALL VENT AT CLEARANCES SPECIFIED BY THE VENT MANUFACTURER.
•
A listed 3” or 4” type “PL ” pellet vent exhaust system must be used for FREESTANDING installation and attached to the
pipe connector provided on the back of the stove. Use a 3” to 4” adapter for 4” pipe. A cap must be used at the
termination of type “L ” vent chimneys.
•
Do not terminate vent in any enclosed or semi-enclosed area, such as; carports, garage, attic, crawl space, under a
sundeck or porch, narrow walkway or close area, or any location that can build up a concentration of fumes such as a
stairwell, covered breezeway etc.
•
Vent surfaces can get hot enough to cause burns if touched by children. Noncombustible shielding or guards ma y be
required. Do not install a flue damper in the exhaust vent of this unit.
•
T ermination must exhaust above air inlet elev ation. It is recommended that at least 5 ft. of vertical pipe be installed
when the appliance is vented directly through a wall. This will create some natural draft to prevent the possibility of
smoke or odor during appliance shutdown and to keep exhaust from causing a nuisance or hazard from exposing
people or shrubs to high temperatures. In any case, the safest and preferred venting method is to extend the vent
through the roof . Do not connect this unit to a chimney flue serving another appliance.
•
Distance from doors and windows, gravity or ventilation air inlet into building:
Not less than 4 ft./1.2m below, 4ft./1.2m horizontally from, 1ft./305mm above(This does not apply if the
windows are non-opening or have been fixed so they cannot open. )
6 USSC
GUIDELINES FOR EXHAUST VENTING SYSTEMS DESIGN continued...
•
Distance from bottom of termination and grade-1ft./305mm minimum. This is conditional upon the plants and nature of
grade surface. The exhaust gases are not hot enough to ignite grass, plants or shrubs located in the vicinity of the
termination. The grade surface must not be a lawn. Distance from bottom of termination and public walkway is 7ft./
2.1m minimum.
•
Distance to combustible materials-2ft./610mm. This includes adjacent building, fences, protruding parts of the structure, roof overhang, plants and shrubs, etc.
•
It is recommended that a single or double clean-out “tee” be installed at every 90
and to permit periodic cleaning of the exhaust system. 90° elbows accumulate fly ash and soot thereby reducing
exhaust flow and performance of the stove.
•
T otal length of horizontal vent must not exceed 48”(4ft. )/1,200mm. All joints in the vent system must be fastened by at
least 3 screws, and all joints must be sealed with RTV silicone sealer to be airtight.
•
When venting into an existing masonry or factory built chimney, the chimney must be cleaned, with all creosote removed. The chimney must be a type suited for solid fuel. WARNING: The chimney and the chimney connections must
be kept clean an in good condition.
•
The “PL ” vent or single wall stainless exhaust system must be installed so as to be GAS TIGHT! The vent manufacturer’s
installation procedures must be followed. In addition, pipe connections, joints and all pipe seams within the home
should be sealed with high temperature RTV silicone sealer.
°
junction to enable collection of fly ash
•
The area where the chimney penetrates to the exterior of the home must be sealed with silicone or other means to
maintain the vapor barrier between the exterior and the interior of the home.
Where installations will be made in locations above 2,000 feet, it is recommended that your stove be installed with 4” pell
vent. At elevations above 3,000 feet, it is mandatory that a 4” pell vent be used for your installation.
NOTE: These are guidelines only. Proper venting is accomplished by design and common sense. In most
installations 3” inch diameter venting is adequate. If it does not vent properly you will have to change it
to 4”.
DO NOT CONNECT TO ANY AIR DISTRIBUTION DUCT OR SYSTEM
USSC 7
DESIGN GUIDELINES FOR OUTSIDE COMBUSTION AIR CONNECTION
For installations with horizontal through-the-wall exhaust, it is strongly recommended that the stove combustion air be
1)
connected to the outside. If the home is newer or has been tightly insulated it is required to install outside combustion
air . If you do not, then bring a 4-6 inch intak e into the furnace room in the basement.
Connection to outside the house is REQUIRED for mobile home installations.

Only noncombustible pipe 3 inches in diameter is approved to use for outside air connections (straight or flexible). PVC
3)
pipe is NOT approved and should NEVER be used.
If the air inlet is connected to the outside, it MUST be terminated with a vertical 90-degree bend (down) or with a wind
4)
hood. Failure to do so could result in a burn back during high winds blowing dir ectly up the air inlet during a simultaneous power failure (see diagram above).
Blockage, excessive length, or bends in the air intake pipe will starve the stove of combustion air. A 90-degree bend is
5)
equivalent in restriction to approximately 30 inches of straight inlet pipe.
CAUTION: The operation of exhaust fans such as bath room fans, attic fans, etc. might starve the heater of combustible air
creating a negative pressure in the room. Provide adequate ventilation in the room ac companying the heater .
