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.
2.2 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.
2. Your Osburn stove is designed to burn
C ORDWOOD F UEL O NLY . 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.
