Permissible fuels

The following fuels are approved:
● Natural shopped wood in the form of billet wood
Maximum length: .....................25 cm
Circumference: .................. 20 - 25 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 calorific value it is
also harmful for the environment. The increased conden-
sate and tar formation can lead to fireplace and chimney
sooting.
This diagram shows that the consumption rate with fresh-
ly-felled wood (calorific value 2.3 kWh/kg) is almost twice
as high as the consumption rate with dry wood (calorific
value 4.3 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 identified by the fact that the fire-
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

• The control lever can be used to set up the grate and
move the ash out of the firebox by sliding the grate
back and forth into the ash box.
• Primary air can only enter the firebox when the grate
is in the open position.
