WOODSTOVE UTILIZATION

Your heating appliance was designed to burn wood only; no other materials should be burned. Waste and 

other flammable materials should not be burned in your 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.

Fuel Recommendations

It is EXTREMELY IMPORTANT that you use DRY WOOD only in your wood stove. 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 stove is 

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. 

TESTING YOUR WOOD

• 

When the stove is thoroughly warmed, place one piece of split wood (about five inches in diameter) parallel 

to the door on the bed of red embers.

•  Keep the air control full open and close the door. If ignition of the piece is accomplished within 90 seconds 

from the time it was placed in the stove, your wood is correctly dried. If ignition takes longer, your wood is 

damp.

• 

If your wood hisses and water or vapor escapes at the ends of the piece, your wood is soaked or freshly cut 

(green). Do not use this wood in your stove. Large amounts of creosote could be deposited in your chimney, 

creating potential conditions for a chimney fire.
