C. Fuel
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
deciduous trees that are definitely not considered hard
-
woods such as poplar, aspen and alder. Hardwoods
require more time to season, burn slower and are usu
-
ally harder to ignite than softwoods. Obviously, you will
use the type of wood that is most readily available in
your area. However, if at all possible the best arrange
-
ment is to have a mix of softwood and hardwood. This
way you can use the softwood for starting the fire, giv
-
ing off quick heat to bring the fireplace up to operating
temperature. Add the hardwood for slow, even heat and
longer burn time.
WARNING! For use with solid wood fuel only.
Other fuels may overfire and generate poisonous gases (i.e.
carbon monoxide).
3. Glass Doors
• Glass doors are optional.
• Refer to Figure 3.3 for how to properly use them.
•
With certain fireplace installations, it may be
necessary to operate the fireplace with both glass
doors in the opened or closed position to prevent
smoke spillage into the home.
