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
embers. Distribute the embers across
the bottom grate, place pieces of
fuel (max. 1,5 kg) on the embers in
a single layer perpendicular to the
firing opening. Close the firing door
and use primary 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 primary airflow. Then adjust
the secondary airflow to the required
amount. For nominal operation (4
kW), the secondary airflow should be
fully open and the primary 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 closed during
normal operation, otherwise the stove
may overheat. It must only be used
until the fuel is burning with a steady
flame.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 conver-
ted to glowing embers.
Optimal firing
To achieve optimal firing and the
highest possible effect, it is important
to make sure that the air supply is
used correctly. As a general rule, the
secondary air is to be used to control
the fire to ignite the flue gases. This
produces 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,
naturally, 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 within
30 to 60 seconds.
A risk of explosion can possibly arise if
too much wood is placed in the stove.
