Permissible fuels
The following fuels are approved:
●
Natural shopped wood in the form of billet wood
Maximum length: ..............33 cm
Circumference: ....approx. 30 cm
●
Wood briquettes to DIN 51731
Size class HP 2
Maximum length: ..............20 cm
Billet wood
reaches a moisture content of 10 to 15%
after being stored outdoors for 2 to 3 years (only cov-
ered at the top) and is then ideally suited for heating.
Freshly cut wood
has a very high moisture content
and so burns badly. Apart from the very low calorif-
ic value it is also harmful for the environment. The in-
creased condensate and tar formation can lead to fire
-
place and chimney sooting.
This diagram shows that the consumption rate with
freshly-felled wood (calorific value 2.3 kWh/kg) is al
-
most twice as high as the consumption rate with dry
wood (calorific value 4.3 kWh/kg).

You will only achieve optimum combustion and heat
in an environmentally friendly way with these fuels.
Adding the fuel in small quantities avoids unnecessary
emissions. Clean burning can be identified by the fact
that the firebrick becomes a light colour.
According to the German Federal Immission Control
Act, it is forbidden e.g. to burn the following fuels in
stoves:
●
Moist wood or wood treated with wood preserv-
atives
●
Sawdust, chippings, grinding dust
●
Bark and chipboard waste
●
Slack coal
●
Other wastes
●
Paper and cardboard (except for igniting)
●
Straw
Please note before heating for the first time
●
Remove all accessories from the ash pan and com-
bustion chamber.
●
The odour given off by the evaporation of the pro-
tective coating disappears after the stove has been
burning for several hours (ventilate the room well).
●
The stove has a high quality temperature resistant
coat, which does not achieve its final strength un
-
til the stove has been heated for the first time. You
should therefore never leave anything on the stove
and not touch the surfaces as the paint coat could
otherwise be damaged.
●
As soon as the kindling material has burned down,
put on 2 burnouts consisting of 3 kg wood ensuring
that the temperature resistant coating reaches its fi
-
nal firmness.
Igniting
● Before ignition, check that no flammable objects are
placed on the stove.
●
Empty the ash pan if necessary and slide back in.
●
Open the combustion air slide valve complete.
●
Grate in open position = operating lever pulled out
●
Place the ignition material (ignition cubes and dry,
smaller ignition wood) and ignite it.
●
Close the combustion chamber door so that the kin-
dling material can catch fire.
●
As soon as the igniting material is burning, add a
quantity of fuel corresponding with the required heat
(see chapter “heating”).
Caution:
When heating up the fireplace, difficulties in igniting the
firewood can occur if a flue draught has not yet formed
in the chimney, and ventilation devices/systems are op-
erated at the same time. In this case briefly opening a
window in the installation room or temporarily switching
off the ventilation system can help.
