Lighting
To ignite the fuel, use fire lighters,
small paraffin ignition bags or small
pieces of wood placed on the bottom
grate. Place larger pieces of wood on
top of this kindling material, at right
angles to the firing, doors. Complet-
ely open the secondary air supply and
leave the firing door ajar – i.e. approx.
1 cm open. Once the fire has taken a
good hold of the fuel and the chimney
has heated up (after about 10 min)
close the firing door. We recommend
that you burn the entire first firing
with the secondary air supply fully
open to make sure that the chimney is
thoroughly heated.
Refiring
You should normally refire the stove
while there is still a good layer of em-
bers. Distribute the embers across the
bottom grate, place pieces of fuel
(max. 1,6 kg) on the embers in a single
layer perpendicular to the firing ope-
ning. Close the firing door and use pri-
mary air if needed. The wood will then
ignite very quickly (within 30 to 60
seconds). When the wood is burning
with a steady flame, close the prima-
ry airflow. Then adjust the secondary
airflow to the required amount. For
nominal operation, the secondary air-
flow should be fully open and the pri-
mary airflow closed. When firing, take
care not to pack the fuel too closely
together, as this will result in poor and
inefficient combustion. Please note
that the primary airflow must be clo-
sed during normal operation, other-
wise the stove may overheat. It must
only be used until the fuel is burning
with a steady flame.
Reduced burning
The stove is well-suited to intermittent
use. If you wish to operate the stove
with reduced out-put, simply insert
smaller volumes of wood at each firing,
and apply a lower airflow. However,
remember that the secondary combu-
stion air supply must never be shut off
completely during firing. It is impor-
tant to keep a good bed of embers.
Gentle heat is released when the fire
settles - i.e. when the wood no longer
generates flames and has been con-
verted to glowing embers.
Optimal firing
To achieve optimal firing and the hig-
hest possible effect, it is important to
make sure that the air supply is used
correctly. As a general rule, the second-
ary
air is to be used to control the fire
to ignite the flue gases. This produ-
ces a high effect and keeps the glass
panel completely clear of soot as the
secondary air “washes” down over it.
Please note that the stove will, natu-
rally, produce soot if both the primary-
and secondary air intakes are closed
completely. This will prevent oxygen
from being drawn into the stove, and
the viewing window and other parts
will become covered with soot. If this
situation is combined with firing with
wet wood, the build-up of soot can
become so thick and sticky that the
sealing rope can, for example, become
detached when the door is opened
the next day.
Risk of explosion
After you add new fuel, it is
very important that you do
not leave the stove unatten-
ded until the wood is burning con-
stantly. This will normally occur wi-
thin 30 to 60 seconds.
A risk of explosion can possibly arise if
too much wood is placed in the stove.
This may result in the production of
large volumes of gas, and this gas can
explode if the intake of primary and
secondary air is insufficient.
It is an advantage always to leave some
ash lying in the bottom of the combu-
stion chamber.
