BURNING SOLID FUELS

Ashes will have to be removed from the stove for proper operation. See cleaning procedure.
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. A few moments of adjustment and cleaning is an important part of burning solid
fuels, due to the vast differences in fuel, humidity and outside temperature.

The American Harvest stove has been designed to burn dry shelled corn, wood pellets and other pelletized fuels that meet
Association of Pellet Fuel Industries standards.

6 USSC

BURNING SOLID FUELS continued...

SHELLED CORN (Dry , preferably 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. Purchase a moisture tester if in doubt.

•

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 for clean filtered bagged corn only. Stalk parts, excessive fines and cob
remnants will clog the auger . Check y our corn for foriegn objects.

•

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.

•

Never burn “Deer Corn. ” It frequently contains molasses/sugars.

•

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 ensure 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. 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 r esult in a more consistant and efficient burn.

•

Check your pellets for foreign objects. Y our stove warranty will not cover damage done to your sto ve due to foreign
objects in the fuel supply .

•

Store your pellets in a dry place to prevent them from absorbing added moisture.

•

T o decrease sawdust buildup, the hopper and auger tube will need to be vacuumed out after ev ery 6-8 bags of pellets
or more often if the pellets are poor quality . The hopper should be empty of fuel when this is performed. 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 dealer
for more information on approved wood pellet fuel.

CAUTION:

DO NOT PLACE SUCH FUELS WITHIN THE SPACE HEATER’S

INSTALLATION CLEARANCES OR WITHIN THE SPACE REQUIRED FOR FUELING AND

ASH REMOVAL.

GUIDELINES FOR EXHAUST VENTING SYSTEMS DESIGN

It is recommended that only an authorized installer install your pellet/corn stove, preferably an NFI certified specialist.

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 UL listed 3” or 4” type “PL” pellet vent exhaust system must be used for 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. 4” PL is required for elevations above 2,500 feet above sea level.

•

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 may be
required.

•

Do not install a flue damper in the exhaust vent of this unit.

•

Termination must exhaust above air inlet elevation. Installation MUST include three (3) vertical feet of pellet vent pipe. 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. Do not connect this unit to a

chimney flue serving another appliance. Do not connect directly to a masonry chimney.

•

The installation must include a cleanout tee to enable collection of fly ash 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. Each elbow
or tee reduces draft potential by 30% to 50%.

45-degree and one 90-degree elbow, etc.) and one cleanout tee to maintain adequate draft. Cleanout tees and elbows
should not be connected to the rear of the unit unless a 3-inch adapter is used.

Total length of horizontal vent must not exceed 48”(4ft.)/1,200mm. The maximum recommended vertical venting height

•

is 15-feet for 3-inch type “PL” vent. Anything more than 15-feet, 4-inch “PL” vent must be used. 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.
The area where the vent pipe 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.

NOTE: These are guidelines only. Proper venting is accomplished by design and necessary requirements. In most
installations 3 inch diameter venting is adequate. If it does not vent properly you will have to change it to 4
inches. You should not exceed 4 inch diameter venting.

Use no more than 180 degrees of elbows (two 90-degree elbows, or two

DO NOT CONNECT TO ANY AIR DISTRIBUTION DUCT OR SYSTEM

VENT TERMINATION CLEARANCES:

A) Min. 4-ft clearance below or beside any door or window that opens.
B) Min. 1-ft clearance above any door or window that opens.
C) Min. 3-ft clearance from any adjacent building.
D) Min. 7-ft clearance from any grade when adjacent to public walkways.
