appropriate length (approx. 22–30
cm) so they can be laid evenly on the
embers. Firewood stored outdoors
should be covered.

Chimney fires
In the event of a chimney fire, close
the firing door and shut off the
secondary/start-up air to smother
the fire. Then call the fire service
immediately. Chimney fires are often
caused by incorrect operation or
long-term use of damp wood.
Regulating the air supply
Open the secondary air by moving
the operating handle at the back
of the side panel. Fig. 1 shows the
secondary air fully open. Gradually
shut off the secondary air by lowe-
ring the handle. The air supply is
fully shut off when the handle is as
shown in Fig. 2.
Open the start-up air to the stove by
sliding the start-up handle fully to
the right (front view). See Fig. 3.

Igniting
To ignite the wood, place firelighters,
small paraffin ignition bags or small
pieces of firewood on the bottom
grate. Then place larger pieces of
firewood on top of the kindling
material perpendicular to the firing
door. Fully open the secondary air
and leave the firing door slightly
open (approx. 1 cm).
When the fire is burning with a stea-
dy flame and the chimney has heated
up (after about 10 min), close the
firing door. We recommend leaving
the secondary air fully open throug-
hout the first firing, to ensure that
the stove and chimney are heated
thoroughly.
Stoking
We recommend stoking the stove
while there is still a good layer of
embers. Spread the embers across the
bottom grate and place up to 2 kg of
firewood on the embers in a single
layer perpendicular to the firing ope-
ning. Close the firing door and feed
in start-up air if required. The wood
will then ignite within 30–60 seconds.
When the wood is burning with a
steady flame, shut off the start-up air
if open. Then adjust the secondary
air to the required level. Nominal
operation (12 kW) is achieved when
the secondary air is fully open and
