Fuel - Osburn 1800 Owner's Manual

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.

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
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.
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.
