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 elements but not the sides.

WOOD STOVE UTILIZATION
This heater is designed to burn natural wood only. Higher efficiencies and lower emissions generally result
when burning air dried seasoned hardwoods, as compared to softwoods or to green or freshly cut hardwoods.
Burning the following materials may result in release of toxic fumes or render the heater ineffective and cause
smoke.
DO NOT BURN:
1. Residential or commercial garbage;
2. Lawn clippings or yard waste;
3. Materials containing rubber, including tires;
4. Materials containing plastic;
5. Waste petroleum products, paints or paint
thinners, or asphalt products;
6. Materials containing asbestos;
7. Construction or demolition debris;
8. Paper products, cardboard, plywood, or
particleboard. The prohibition against burning
these materials does not prohibit the use of fire
starters made from paper, cardboard, saw dust,
wax and similar substances for the purpose of
starting a fire in unaffected wood heater.
9. Railroad ties or pressure-treated wood;
10. Manure or animal remains;
11. Salt water driftwood or other previously salt
water saturated materials;
12. Unseasoned wood;
13. Any materials that are not included in the
warranty and owner’s manual for the subject
wood heater; or
14. Any materials that were not included in the
certification tests for the subject wood heater.
