Woodstove Utilisation - Drolet NG1800 Austral Owner's Manual

WOODSTOVE UTILISATION

Your heating unit was designed to burn wood only; no other materials should be burnt. Wastes
and other flammable materials should not be burnt in your wood stove. Any type of wood may
be used in your stove, but specific varieties have better energy yields than others. Please
consult the following table in order to make the best possible choice.

IT IS EXTREMELY IMPORTANT THAT YOU USE DRY WOOD ONLY IN YOUR WOOD
STOVE. The wood must have dried for 9 to 15 months, such as 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 since one, two or even more years, it is not necessarily dry, if it has been
stored in poor conditions; under extreme conditions, it may even rot instead of drying. The vast
majority of the problems related to the operation of a wood stove are caused by the fact that the
wood used was too damp or had 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 element but not the
sides.
