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.

Installing the stove

The floor on which the stove is installed must be even
and horizontal. The stove may only be installed on an
adequate load­bearing floor. The stove can be stood
on a metal floor sheet or glass sheet to protect the
flooring.
If the flooring or carpet is inflammable, a stable, heat
proof spark protection plate must be used. This must
extend 50 cm to the front and 30 cm to each side be-
yond the edge of the combustion chamber opening.
Under the stove no spark protection plate is required.

Assembly sequence

● The Ø 150 stovepipe connection can be installed at
the top or rear. The stove is supplied ready for con-
nection from above. If you wish to connect it at the
rear, the following steps must be carried out to make
the necessary modifications:
- Break out the cover in the back panel.
- Replace the connector sleeve and the sealing
cover.
● If intended, install the OEC (see chapter "OEC
installation").
● If no OEC is to be installed, carefully remove the
foam sheet between the lower front shield and the
bottom plate.
● Decide where the stove is to be installed. There
must be no objects made of combustible materials
within a distance of 80 cm of the stove's radiation
area, measured from the combustion chamber's in-
spection glass, nor may any be placed within this
area subsequently.
Depending on the installation position of the stove in
front of walls that need to be protected (flammable
or load-bearing), the following distances from walls
need to be observed in accordance with the position
of the combustion chamber door to the wall / side
panel or the back panel (see schematic diagram).
When not dealing with walls that need to be protect-
ed, you merely need to observe a minimum distance
of approx. 5 cm to allow for proper heat dissipation.
