scribed below:
• Initial (cold) Startup
Leave fan off until your fireplace is hot and a good
coal bed is established, approximately 30 minutes
after fuel is lit.

The fan may be left on throughout the burn.
• Medium or Medium High Burn Setting
The fan should be left off until a good burn is
established, then turned on medium or high rate.

until the burn is well established; then, if you wish,
turn the fan on at a low rate.

carbon monoxide).

1. Hardwood vs. Softwood

Your fireplace's performance depends on the quality of
the firewood you use. One species of wood varies very
little to the other in terms of energy content. All sea-
soned wood contains about 8,000 BTU's per pound.
Hardwoods have a greater density than softwoods; a
piece of hardwood will contain about 60% more BTU's
than an equal size piece of softwood. A cord of sea-
soned oak (hardwood) would contain about 60% more
potential energy than a cord of seasoned pine (soft-
wood).
Most softwoods are coniferous. These are trees with
needle-like leaves that stay green all year and carry
their seeds exposed in a cone. Examples of conifer-
ous trees are Douglas fir, pine, spruce and cedar. Soft-
woods, being more porous, require less time to dry,
burn faster and are easier to ignite than hardwoods.
Hardwoods are deciduous trees, broadleaf trees that
lose their leaves in the fall. Their seeds are usually
found within a protective pod or enclosure. Some ex-
amples of deciduous trees are oak, maple, apple, and
birch. However, it should be noted that there are some
