Operation

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 EN 14691
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 covered 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 calorifi c value it is
also harmful for the environment. The increased conden-
sate and tar formation can lead to fi replace and chimney
sooting.
This diagram shows that the consumption rate with fresh-
ly-felled wood (calorifi c value 2.3 kWh/kg) is almost twice
as high as the consumption rate with dry wood (calorifi c
value 4.3 kWh/kg).
Caloric value [kWh/kg]
dry wood that has been stored for at least 2 years
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 identifi ed by the fact that the fi re-
brick 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
preservatives
● Sawdust, chippings, grinding dust
● Bark and chipboard waste
● Slack coal
● Other wastes
● Paper and cardboard (except for igniting)
● Straw
freshly-felled wood

Please note before heating for the fi rst time

● Remove all accessories from the ash pan and combus-
tion chamber.
● The odour given off by the evaporation of the protec-
tive coating disappears after the stove has been burn-
ing for several hours (ventilate the room well).
● The stove has a high quality temperature resistant coat,
which does not achieve its fi nal strength until the stove
has been heated for the fi rst 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 fi rmness.

Igniting

● Before ignition, check that no fl ammable 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
● Stack small amounts of fi rewood and, on top of it, kin-
dling material (igniter cubes and dry, smaller kindling)
and set the material alight.
● Close the door to the combustion chamber so that the
kindling material can catch fi re.
● Once there is a basic fi rebed, add more fuel according to
the heat requirement (see chapter "Heating").
Caution:
When heating up the fi replace, diffi culties in igniting the
fi rewood can occur if a fl ue draught has not yet formed in
the chimney, and ventilation devices/systems are operat-
ed at the same time. In this case briefl y opening a window
in the installation room or temporarily switching off the
ventilation system can help.
