Fuel Considerations
SHELLED CORN (Dry, preferably corn with 11% or less moisture content)

Optimum moisture content of corn should be 11% or less. Wet corn will rapidly deteriorate furnace components,
reduce efciency 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 eld. Damage caused by dirty corn is not
covered by the product warranty. Ask for clean ltered, bagged corn only. Stalk parts, excessive nes and cob
remnants will clog the auger.
NEVER BURN SEED CORN IN YOUR FURNACE. 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. Test the moisture content periodically to ensure 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. Your furnace 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. There-
fore, purchasing corn from the same source will help achieve a more consistent burn. DO NOT USE CORN WITH
A HIGH WAX CONTENT!
Oyster shell is highly recommended for best burn operations and to reduce clinker build-up
WOOD PELLETS
•
•
•
•
•
As with corn, be consistent with your pellet supplier. Pellets will vary in content and burn characteristics from sup-
plier to supplier. A consistent supply of pellets will result in a more consistent and efcient burn.
Check your pellets for foreign objects. Your furnace warranty will not cover damage done to your furnace due to
foreign objects in the fuel supply.
Store your pellets in a dry place to prevent them from absorbing added moisture.
To decrease sawdust buildup, the hopper will need to be vacuumed out after every 6-8 bags of pellets or more often
if the pellets are poor quality. You may have to screen-sift each bag of pellets if sawdust becomes a problem.
Wood Pellets vary in size and ash content from less than 1% to 3% or more. Your furnace will burn more efciently
with small to midsize pellets. Low ash content pellets will allow you to burn the furnace longer between cleanings.
Only wood pellets manufactured to the Pellet Fuel Industries (P.F.I.) standard for residential pellet fuels are recom-
mended. Performance will suffer if nonstandard pellets are used. Consult your local King reseller for more informa-
tion on approved wood pellet fuel.
If fans are used in the fuel storage area, they should be installed so as not to create a negative pressure in the room
where your furnace is located.
CAUTION: DO NOT PLACE SUCH FUELS WITHIN THE SPACE HEATER’S INSTALLATION
CLEARANCES OR WITHIN THE SPACE REQUIRED FOR REFUELING AND ASH REMOVAL.

SAFETY AND EPA COMPLIANCE
Your King Furnace has been safety tested and listed to UL 391-2010, ASTM E1509-04, and CSA-B366.1-11, by OMNI-
Test Laboratories, Inc. Portland, Oregon USA. It is also exempt from EPA Phase II requirements.
