Regulations to be observed

● Local and building law regulations
● The stove must be installed by a professional and
connected to the chimney. The specific national reg-
ulations for safe installation of the connector must be
complied with. The connecting piece used must pos-
sess an opening for cleaning.
● The stove must be regularly checked by a
professional.
The heating stove's fire door is self-closing; it is there-
fore approved for connection to chimneys with multiple
connections.

Chimney design

The chimney design is according to EN 13384-1 and -2
or to the specific national regulations. The chimney
must comply with the temperature class T400.

Combustion air supply

It must be guaranteed that there is enough combustion
air available for the stove. For the proper function of the
stove, a necessary combustion air volume current of
18,7 m³/h must be considered.

External combustion air connection

By an external operating mode, the combustion air
can be added from outside through a leak-proof line or
through a supply duct in the chimney. Thus, speak with
your district chimney sweep master.
Due to energy saving reasons, the combustion air in-
let should be able to be blocked if the stove is not being
operated. This can occur through a shut-off valve in the
combustion air line or through the air slide valves on
the stove. If a shut-off valve is used, this must be clear-
ly identified with CLOSED/OPEN.
Through the shutoff, it is avoided that heat is removed
from the set-up room through the constant circulation
of cold combustion air and cold combustion air lines
may lead to an increased formation of condensation.
Attention:
The combustion air line may not be closed during
operation!
In order to feed the combustion air to the stove exter-
nally via a pipe instead of from the room in which it is
installed, it is possible to screw a Ø 125 mm combus-
tion air pipe to the back of the stove. If the combus-
tion air pipe installed is longer than 3 m, calculations
will have to be carried out to verify an adequate sup-
ply of combustion air. At extremely low outdoor temper-
atures, condensation can occur on the combustion air
duct. For this reason it must be insulated with a suitable
insulating material. Observe the rules of the oven and
air heating construction craft.
Use the Olsberg combustion air pipes with sealing lip.
Attention:
Appliances with external combustion air connec-
tion are not suitable for concurrent operation with
ventilation systems, without a supplemental safe-
ty system.
