Installation and Operation Manual - Inspire 2000 Insert
3.2 Log Length
Logs should be cut at least 1" (25 mm) shorter than the firebox so they fit in easily.
Pieces that are even slightly too long makes loading the insert very difficult. The
most common standard length of firewood is 16" (400 mm).
3.3 Piece Size
Firewood dries more quickly when it is split. Large
unsplit rounds can take years to dry enough to burn.
Even when dried, unsplit logs are difficult to ignite
because they don’t have the sharp edges where the
flames first catch.
Wood should be split to a range of sizes, from about 3" to 6" (75 mm to 150 mm) in cross
section. Having a range of sizes makes starting and rekindling fires much easier.
3.4 Compressed Wood Logs
Compressed wood logs made of 100% compressed sawdust can be
burned with caution in the number of these logs burned at once. Do
not burn compressed logs made of wax impregnated sawdust or logs
with any chemical additives. Follow the manufacturer’s instructions
and warnings.
3.5 Drying Time
Firewood that is not dry enough to burn is
the cause of most complaints about wood
burning 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 insert to produce
its highest possible efficiency.
Here are some things 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;
− Drying happens faster in dry weather than in a damp climate;
− Drying happens faster in warm summer weather than in winter weather;
− Small pieces dry more quickly than large pieces;
− 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;
