3.9. WOOD
Logs of correct size for the stove allow for better
stacking, filling and operation of your stove (see table
below). Use dry wood which, by definition, is wood
which has been dried under cover for more than 18
months so that the logs contain less than 20%
moisture.

Heating the air in a closed building decreases the
relative humidity of the air, which will dry wood and
other combustible materials. This drying lowers the
ignition temperature of these material, thus increasing
the fire hazard. To reduce the risk of fire, some
provision should be made for replenishing moisture to
the air whenever a structure is being heated for
extended periods.
Use dry wood
Some types of wood are easier to light than others. The
best fire wood, and easiest to light, is always dry wood.
Using dry wood will minimise creosote build-up. Damp
wood has far less heating power. This lowers the
combustion temperature of the fire, and therefore the
output. It is difficult to light, burns badly and gives off
smoke. Above all, the use of damp wood causes the
formation of deposits (tarring and soot staining) in the
chimney flue and on the glass door.
Flue gas temperature
The most important aspect of stove operation is
maintaining a high combustion temperature. If the
combustion of the fuel is at the correct temperature,
most of the soot and tars (hydrocarbons) are burned.
These hydrocarbons, when not burned, can be seen as
tar and creosote deposits on the internal surfaces of
the stove, glass and chimney surfaces.
Running your stove at maximum for prolonged periods
will chill the stove as the airs passage through the
combustion chamber will be too fast to heat up and
maintain the temperature within the stove. The

operator will soon become acquainted with the
optimum settinng for the maximum heat production
from their stove without the use of any surface or flue
thermometer.
High combustion temperatures are the secret to clean
glass operation. When loading wood, add one or two
logs at a time, depending on size. Loading the appliance
full of damp wood on a low fire is certain to cause poor
combustion efficiency, resulting in tar and dirty glass.
It is recommended that you heat your stove to at least
205°C (400°F) before reducing the air controls. This
procedure should always be carried out after
reloading. A simple guide to this is when the new
charge of fuel is burning vigorously.
Storage time for wood

immediately under a ventilated shelter dries quicker
than wood stocked in high piles. Quarters (split wood)
dry quicker than round logs. Wood which is too small
to split must be drained, by removing some of the bark.
Round logs left in the open for more than a year end
up rotten. The drying time for the fire wood should be
at least 18 months to 2 years. This period can be
shortened (12 to 15 months) if the wood is cut to the
right length and immediately stored under a ventilated
shelter.
4. SAFETY
Notify the elderly, as well as children of the high
surface temperature of the stove in order to avoid
burns. Supervise children when they are in the room
where the stove is placed and use a suitable fire guard
for it. It is essential that the controls of the stove, as
well as the chimney pipes are always clean and in good
condition. The stove must be checked before use, as
well as the chimney cleaned at least once a year. You
should do this operation more often if the stove does
not turn on regularly, the installation is poor or low
quality fuel is used.
ATENTION: The stove is very hot during operation. Do
not touch the surface. Furniture and other
combustible materials must keep the necessary safety
distance (Fig. 22).
