Choosing Firewood
Burn only natural firewood (known as cordwood)
in the Mansfield 8011 Woodstove. This stove is
not designed to burn other fuels.
CAUTION: DO NOT USE CHEMICALS OR
FLAMMABLE FLUIDS TO START THE 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 directly affects heat
output, duration of burn and performance of your
stove. Softwoods generally burn hotter and faster,
while hardwoods burn longer and produce better
coals. Density and moisture content are two critical
factors to consider when purchasing wood for your
stove.
The following is a list of some wood species and
their relative BTU (British Thermal Unit) content. The
higher the BTU content, the longer the burn.
Firewood with higher BTUs is generally ideal for a
wood stove.

Moisture content also plays a key role in the
performance of your stove. Wood freshly cut from a
living tree (green wood) contains a great deal of
