It is EXTREMELY IMPORTANT that you use DRY WOOD only. The wood should have dried for 9 to 15 months, such
that the humidity content (in weight) is reduced below 20% of the weight of the log. It is very important to keep
in mind that even if the wood has been cut for one, two or even more years, it is not necessarily dry, if it has
been stored in poor conditions. Under extreme conditions it may rot, instead of drying. This point cannot be over
stressed; the vast majority of the problems related to the operation of a wood furnace is caused by the fact that
the wood used was too damp or has dried in poor conditions.
These problems can be:
• Ignition problems
• Creosote build-up causing chimney fires
• Low energy yield
• Blackened windows
• Incomplete log combustion
Smaller pieces of wood will dry faster. All logs exceeding 6” in diameter should be split. The wood should not be
stored directly on the ground. Air should circulate through the cord. A 24” to 48” air space should be left between
each row of logs, which should be placed in the sunniest location possible. The upper layer of wood should be
protected from the elements but not the sides.
