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 Pico Compact stove can be operated convention-
ally, dependent on the ambient air as well as independ-
ent of the ambient 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
installed, it is possible to screw a Ø 125 mm combus-
tion air pipe to the back of the stove or at the bottom.
If attaching the combustion air line at the rear of the ap-
pliance, remove the cover seated on the rear base pan-
el and screw in the included connection duct through
the hole in the rear base panel fitted on the appliance.
f the combustion air is supposed to be supplied from
the bottom, remove the cover seated on the rear base
panel and use the cover to seal the opening in the ap-
pliance through the hole in the rear base panel. The
combustion air line routed up from the bottom ends
flush with the floor on which the appliance is installed.
A flange with a sealing lip that provides for an air­tight
connection between the appliance and the floor on
which it is installed has been included with the appli-
ance to fit this type of installation scenario. Refer to
Fig.3 to Fig.6 for the position of the combustion air line.
When installing the flange, make sure the sealing lip,
which is approx. 20mm in height, faces down towards
the floor on which the appliance is installed (see Fig.1).
If opting for a distance greater than the minimum dis-
tance to the mounting wall, you need to adjust the posi-
tion of the combustion air line accordingly.
If the combustion air pipe installed is longer than 3 m,
calculations will have to be carried out to verify an ad-
equate supply of combustion air. At extremely low out-
door temperatures, condensation can occur on the
combustion air duct. For this reason it must be insulat-
ed 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.
