3.2 FUEL
Fuel for the stove must not be stored closer than the required clearances to combustibles (heat sensitive
materials). NEVER STORE WOOD IN THE ASH PAN COMPARTMENT.
Your Drolet stove is designed to burn
WOOD ONLY
. Do not burn coal, charcoal, or trash in the unit. Highly
flammable items such as trash may ignite creosote in the chimney (flue), 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.
Seasoned cord wood is recommended. Wood should be air dried in a covered and ventilated area for a
minimum of six months (one year or more is recommended). This reduces the moisture content of the wood,
resulting in a better stove performance. Wood species with moisture content of 20% or less are ideal. Dry,
seasoned cord wood, can be distinguished from green wood by the cracks at each end of the logs. 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.
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
found
un North America is given in Table 3.2 below.
