Environmentally-Friendly Heating
Avoid restricting your wood-burning stove to an extent where no
flames are visible during the degasifying period, as this leads to
particularly inefficient heating. The gases released by the wood do
not burn due to the low temperature in the combustion chamber.
Part of the gas condenses in the wood-burning stove and flue
system as soot, and this could lead to your chimney catching fire.
The smoke that exits the chimney is bad for the environment and
has an unpleasant smell.

Lighting

We recommend the use of fire starters, or similar products, which
are available from your Scan dealer. Using fire starters helps to light
the wood quicker, and keeps the burning process clean.
Never use liquid lighting fuels!
"Top down" lighting
2 logs approx. 30 cm long with a weight of approx. 1.0 – 1.3 kg per
piece.
1 log approx. 25 cm long with a weight of about 0.5 kg.
8 - 16 kindling sticks of about 20 cm with a total weight of approx.
400 g. 3 fire starters.
Position the large logs in the centre of the combustion chamber 1-2
cm apart as shown. Put half the kindling sticks across the logs in
a criss-cross fashion. Place the smallest log on top of the sticks as
shown and arrange the last sticks in front of the log. Position the
firestarters between the sticks and light
Set the combustion airflow controls to maximum for about 20 - 30
minutes. When the two larger logs have caught fire properly, you
can set the combustion airflow to the desired level.
Top down lighting gives a more environmentally friendly start to
your fire and helps to keep the glass areas as clean as possible.
Continuous firing
It is important to reach as high a temperature as possible in the
combustion chamber. This makes the most efficient use of the wood-
burning stove and fuel, and ensures a clean burning process. At the
same time, this avoids soot build-up on the combustion chamber
walls and glass. While the stove is lit, you should not see any smoke,
but just air movement that indicates the burning process.
After completing the lighting phase, you should have a good layer of
embers in the woodstove; you can then start stoking up the stove.
Lay 2 logs, of about 1.0 - 1.2 kg weight with a length of about 30 cm
onto the fire.
Note! The wood must catch fire quickly; this is why we recommend
setting the combustion airflow to full power. Running the stove at
too low a temperature and with too little combustion air can lead
to deflagration of the gases, and thus cause damage to the stove.
When stoking up with wood, always open the glass door carefully
to avoid smoke escaping. Stoke up with wood while the fire is still
burning nicely. If it seems that the woodstove is burning your fuel
too quickly, you can adjust the damper in the flue pipe (see page 7).
Using your stove in the spring or autumn
Occasional lighting of the stove using the "top down" lighting
method is recommended in changeable weather such as in spring/
autumn when your heating requirements are not as great.
Heating with open door
Note that your wood-burning stove was not designed for continuo-
us heating with the door open, as this mode of operation will mean
inefficient burning, poor heating performance, and higher emission
levels.
However if you do leave the wood-burning stove door open during
use, note that smoke may escape from the stove into the room
where the stove is located. The reason for this is that the smoke
temperature at the top of the chimney is lower than the ceiling
temperature in the room where the stove is located, and this causes
lower pressure in the room than in the chimney. Smoke may thus be
drawn into the room. Whether or not smoke actually escapes into
the room depends on your chimney design. Try heating the stove
with the door open in different weather conditions. If no smoke
escapes into the room, your installation is excellent. But if smoke
escapes from the wood-burning stove into the room, make sure you
fit a smoke extractor to the chimney to avoid smoke build-up in the
room where the stove is located.
Why you need a chimney
The chimney is the wood-burning stove's motor; it's performance
decides how well your stove will work. The draft in the chimney
creates a vacuum in the wood-burning stove. The vacuum draws the
smoke out of the stove, and takes in air through the combustion air
baffle to fuel the burning process. Combustion air is also used for
the airwash system that keeps the window clear of soot.
The draft in the chimney is caused by the difference in temperatures
inside and outside the chimney. The higher the temperature diffe-
rence is, the better the draft in the chimney will be. It is thus impor-
tant for the chimney to reach operating temperature before you
adjust the damper to restrict combustion in the stove (a brickwork
chimney will take longer to reach operating temperature than a
steel chimney). It is very important to reach operating temperature
as quickly as possible on days on which the draft in the chimney is
poor due to unfavorable wind and weather conditions. Make sure
the fuel ignites as quickly as possible (with visible flames). Chop
the wood into particularly small pieces; use an extra fire lighter etc.
After longer periods of disuse, check the chimney flue for blockage.
You can connect several units to the same chimney. But make sure
check with your chimney sweep to observe local regulations.
No matter how good your chimney is, it will not perform well if you
do not use it correctly. On the other hand a poor chimney, may give
you acceptable results if you use it correctly.
