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 stove has national technical approval from the
Deutsches Institut für Bautechnik (DIBt) (German
Institute for Civil Engineering) for room-air independ-
ent operation.
Due to its general technical approval, the stove can
be used simultaneously with an approved ventila-
tion system without additional safety device.
Equipped with a self-closing combustion chamber
door, the stove is approved to be connected to multi-
flue chimneys provided that it operates with a room­air
dependent combustion-air supply.
Room-air independent operation requires that the ex-
haust gases of the fireplace be discharged through a
single­flue chimney or the exhaust duct of a single­flue
air-exhaust chimney. Exhaust gases may also be dis-
charged into multi­flue exhaust gas systems if all con-
nected fireplaces are part of the same utilisation unit/
action range of the ventilation system. Individual differ-
ences can be discussed with your district master chim-
ney sweep.
Chimney design
The chimney design is according to DIN EN 13384-1
and
­2 or to the specific national regulations. The chim-
ney must comply with the temperature class T400.

Combustion air supply
The stove can be operated conventionally, dependent
on the ambient air as well as independent of the am-
bient air.
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
15,6 m³/h must be considered.
Ambient air independent
combustion air connection
By an ambient air independent operating mode, the
combustion air must 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 in-
stalled, 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, calcu-
lations will have to be carried out to verify an adequate
supply of combustion air. At extremely low outdoor tem-
peratures, condensation can occur on the combustion
air duct. For this reason it must be insulated with a suit-
able insulating material. Observe the rules of the oven
and air heating construction craft.
Use the Olsberg combustion air pipes with sealing lip.
