10.
Never operate the stove with the door open, or cracked slightly open, except
briefly during the lighting operation, and during refuelling. Leaving the door open
continuously could seriously overheat the chimney and adjacent combustibles.
Do not operate the stove if there is an abnormal air leakage into the stove, such
as through deteriorated gaskets or cracked or broken glass. Do not operate the
stove without a door gasket. Leakage can result in overheating, or in very
airtight homes, could possibly cause smoking into the room. Smoke may
contain carbon monoxide, which is poisonous, and in sufficient quantities is a
health hazard.
FUEL
1.
Fuel for the stove must not be stored closer than the required clearances to
combustibles and not in the space required for charging and ash removal.

. Do not burn coal,
charcoal, or trash in the unit. Highly flammable items such as trash may ignite
creosote in the chimney, resulting in a chimney fire. Never burn salt wood,
beach wood, chemically treated wood, or wood removed from salt water, since
the deposits left will deteriorate the firebox. Damage caused by chemicals or
salt is not covered under warranty.
3.
Seasoned dense wood is recommended. Wood should be air dried in a
covered ventilated area for six months to a year or more. This reduces the
moisture content of the wood, resulting in better stove performance. Wood
species with moisture content of 20% or less are ideal. Dry seasoned wood can
be distinguished from green wood by the checks or cracks in the ends.
4.
Wet or green wood will tend to cause the fire to smoulder, producing large
amounts of creosote. Creosote buildup could result in a chimney fire. This
wood will also prove difficult to keep burning properly, and fires will tend to go
out. Green wood produces very little heat, and sometimes causes customers to
think that the stove does not work. If you must burn wet wood, use only small
amounts mixed with dry wood.
5.
Decayed wood or low-density wood has very little energy content or heating
value, and will not burn satisfactorily for long periods of time.
An example of the energy values of some common wood fuels is given in Table 2.1
For recommended wood sizes, refer to the specifications.
