3.1

Tree Species

The tree species the firewood is produced from is less important than its moisture content. Softer
woods make good fuel for mild weather in spring and fall because they light quickly and produce
less heat. Softwoods are not as dense as hardwoods so a given volume of wood contains less
energy. Using softwoods avoids overheating the house, which can be a common problem with
wood heating in moderate weather. Harder woods are best for colder winter weather when more
heat and longer burn cycles are desirable.
3.2

Drying Time

Firewood that is not dry enough to burn is the cause of most complaints about wood appliances.
Continually burning green or unseasoned wood produces more creosote and involves lack of
heat and dirty glass door. Firewood with a moisture content between 15% and 20% will allow
the fireplace to produce its highest possible efficiency.
Here are some facts to consider in estimating drying time:
− Firewood bought from a dealer is rarely dry enough to
burn, so it is advisable to buy the wood in spring and
dry it yourself;
− Split pieces dry more quickly than unsplit rounds;
− Softwoods like pine, spruce, poplar, and aspen take
less time to dry than hardwoods. they can be dry
enough to burn after being stacked to air dry only for
the summer months;
− Hardwoods like oak, maple and ash can take one, or even two years to dry fully, especially if the
pieces are big;
− Firewood dries more quickly when stacked outside in a location exposed to sun and wind; it takes
much longer to dry when stacked in a wood shed;
Use these guidelines to find out if the firewood is dry enough to burn:
− Cracks form at the ends of logs as they dry;
− The wood turns from white or cream colored to grey or yellow;
− Two pieces of wood struck together sounds hollow;
− Dry wood is much lighter in weight than wet wood,
− The face of a fresh cut feels warm and dry;

4. Operating the Fireplace

This wood heater has a manufacturer-set minimum low burn rate that must not be
altered. It is against federal regulations to alter this setting or otherwise operate this
wood heater in a manner inconsistent with operating instructions in this manual.
4.1

Fire Screen

This fireplace has been tested for use with an open door in conjunction with a fire screen, sold
separately. The fire screen must be properly secured on the fireplace to avoid any risk of sparks
damaging the flooring. When the fire screen is in use, do not leave the fireplace unattended to
respond promptly in the event of smoke spillage into the room.
