APPROvED FUEL TYPES

APPROvED FUEL TYPES
Corn, Wheat and Grain
Shelled corn, wheat and grain pellets must have
16% or less moisture content. The keys to satisfac-
tory performance are proper operation of the fur-
nace, diligent maintenance, and burning only dry,
clean, quality fuel. These fuels must be screened to
remove dust prior to using.
clinkers and ash are by-products of burning biomass fuels and
are not caused by your furnace. Furnace performance is re-
duced if poor quality fuel is used. Using a thermostat will cause
variations in the maintenance. check the burn pot frequently
in the beginning to establish a maintenance schedule based
on fuel use and burn rates. contact your dealer for more infor-
mation on where to get high quality biomass fuels to burn in
your furnace. Store fuel in an air tight container or use other
methods to ensure they do not become rain soaked or absorb
moisture from damp or wet floors. This will also prevent rodents
from becoming a problem. do not store fuel within furnace in-
stallation clearance areas or within the space required for ash
removal. The 50F furnace is not warranted against damage
caused by poor quality fuel, incorrect operation, poor mainte-
nance or incorrect installation.

10. P Pellet
Fuel Description:
High ash = any High ash Fuel
L Wheat = Lower Wheat
Wheat = Normal Wheat
HM corn = High Moisture corn (16 - 14%)
corn = normal corn (15 - 13%)
LM corn = Low Moisture corn (14 - 12%)
cherry Pit = cherry Pits
LG Pellet = Low Grade Pellets
S Pellet = Standard Pellets
P Pellet = Premium Pellets
NOTE: Excessive grain dust must
be screened by sifting with mesh
screening. Large pieces of cob
