Proper installation and correct handling and care are in-
dispensable for problem-free operation and a long ser-
vice life. Please therefore observe all the information giv-
en in these instructions. We are convinced that you will
then derive a great deal of pleasure from this stove. Please
keep these instructions in a safe place so that you can read
through them at the start of each heating period.
Should you find any transport damage, please report it to
your supplier immediately as otherwise it will not be pos-
sible to correct the damage free of charge.

Dimensions in cm
Regulations to be observed
● Local and building law regulations
● The stove must be installed by a professional and con-
nected to the chimney. The specific national regulations
for safe installation of the connector must be complied
with. The connecting piece used must possess an open-
ing 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 DIN 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 combus-
tion air available for the stove. For the proper function of
the stove, a necessary combustion air volume current of
15 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 inlet
should be able to be blocked if the stove is not being op-
erated. This can occur through a shut-off valve in the com-
bustion air line or through the air slide valves on the stove.
If a shut-off valve is used, this must be clearly 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 externally
via a pipe instead of from the room in which it is installed,
it is possible to screw a Ø 125 mm combustion air pipe to
the back of the stove or at the bottom. If the combustion
air pipe installed is longer than 3 m, calculations will have
to be carried out to verify an adequate supply of combus-
tion air. At extremely low outdoor temperatures, conden-
sation can occur on the combustion air duct. For this rea-
son it must be insulated with a suitable insulating materi-
al. Observe the rules of the oven and air heating construc-
tion craft.
Use the Olsberg combustion air pipes with sealing lip.
Attention:
Appliances with external combustion air connection
are not suitable for concurrent operation with venti-
lation systems, without a supplemental safety system.
