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. Do not poke or stir the logs while they
are burning.
Use only logs that meet the requirements of ULC/ORD C127 M1990 for composite logs.
Refer to package cautions and warnings before using logs.
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 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;
− Drying happens faster in dry weather than in a
damp climate;
− Drying happens faster in warm summer weather
than in winter weather;
− 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;
− Firewood with a moisture content of 15% to 20% will allow the fireplace to reach its highest
efficiency.
Firewood is dry enough to burn when:
− Cracks form at the end of logs;
− The wood turns from white or cream colored to grey or yellow;
− Two pieces of wood struck together sounds hollow;
− The face of a fresh cut feels warm and dry;
− The moisture content read by a moisture meter is between 15% to 20%.
