CHOOSING FIREWOOD
Burn only natural firewood (known as cordwood)
in the Heritage 8022 Woodstove. This stove is
not designed to burn other fuels.
 CAUTION: DO NOT USE CHEMICALS OR
FLAMMABLE FLUIDS SUCH AS GASOLINE,
NAPHTHA, KEROSENE, CHARCOAL LIGHTER
FLUID OR ENGINE OIL TO START A FIRE. DO
NOT USE CHARCOAL, PELLETS, COAL,
ARTIFICIAL LOGS OR ANY OTHER MATERIALS
AS FUEL; THEY ARE NOT SAFE. DO NOT BURN
GARBAGE OR FLAMMABLE FLUIDS.
The quality of your firewood affects heat output,
duration of burn and performance of your stove.
Softwoods generally burn hotter and faster, while
hardwoods burn longer and produce more long
lasting coals. Density and moisture content are two
critical factors to consider when purchasing wood for
your stove.
The following is a list of many common wood
species and their relative BTU (British Thermal Unit)
content. The higher the BTU content the longer the
burn. Firewood with higher a BTU content is
generally considered ideal for a wood stove.

Moisture content plays a key role in the performance
of your stove. Wood freshly cut from a living tree
(green wood) contains a great deal of moisture. You
must season green wood before using it in your
wood stove. To season green wood properly, split,
stack, and allow it to air dry for a period of one year.
Green wood may provide less than 2000 Btu per
pound, whereas dry wood can provide up to 7000
Btu per pound.
