2. Installation Conditions and Relevant Building
Regulations
The stove must be installed in accordance with the instructions
and requirements stipulated by the respective national and
European standards and local regulations.
In Germany, the stove must be registered with the local master
chimney sweep for inspection prior to initial operation.
3. Installation
Check to make sure that the load-bearing capacity of the in-
stallation surface is sufficient. If necessary, using a floorplate
to distribute the load can increase the load bearing capacity.
Check whether the room in which the stove will be installed is
adequately supplied with enough fresh air. If the windows and
doors are tightly sealed, the necessary supply of fresh air may
not be ensured, which can interfere with the draught capability
of the stove and chimney.
If additional combustion air inlet openings are required, they
are not permitted to be closed or blocked.
CAUTION!
Simultaneous operation of the stove with venti-
lation systems and/or exhaust hoods can cause
negative pressure to build up in the room where
the stove is installed, which can lead to pro-
blems such as flue gas escaping from the stove.
NOTE!
To ensure that air is not drawn out of the room
where the stove is installed, we recommend
using a window contact switch to lock exhaust
hoods that guide the air to the outside.
4. Chimney
The stove has to be connected to a
suitable
chimney with a
minimum effective chimney height of 4.50 m.
The exhaust system temperature class (smoke pipe and boiler
tube) must be at least T400 soot fire-resistant. To determine
whether your stove can be connected to a chimney to which
other fireplaces are already connected, please consult the tech-
nical data contained in the operating instructions (part I). The
chimney cross section should correspond to the flue pipe cross
section. If the effective chimney height is too low and/or the
chimney cross section is too large or too small, the draught
capability of your stove can be impaired.
The minimum output pressure (chimney draught) for your
stove model is specified in the technical data contained in the
model-specific operating instructions (part I). At output pres-
sures higher than specified, the stove emissions increase which
puts a high load on the stove and can lead to damage.
The stove has a maximum permissible output pressure of 20
Pa. To limit the output pressure, a butterfly valve (
a
) (Fig. 2)
or output pressure limiter can be used. Please perform a cross-
section calculation compliant with EN 13384-1/2 if there is any
doubt as to whether the flue gas system is working correctly.
5. Flue Pipe Connection
The flue pipe diameter required to connect your stove is speci-
fied in the technical data contained in the model-specific ope-
rating instructions (part I). Please ensure that all pipe pieces are
tightly fit at the connection junctions. We recommend using
elbow pipes with cleaning hatches.
CAUTION!
The flue pipe must be well sealed at the chim-
ney entrance and cannot project into the in-
ner cavity of the chimney; otherwise the flue
venting will be impaired (Fig. 1).

6. Butterfly Valve
The butterfly valve (
a
) (Fig. 2) is an optional control element.
It is fitted in the flue pipe and used to regulate the flue gas
flow, and can thus slow down the burning-off process. When
the handle’s position is diagonal to the flue pipe, the flue gas
flow rate is turned to minimum. In the case of increased pump
pressure in the chimney unit, we recommend the installation
of a butterfly valve.
Please comply with the country-specific
legal regulations.
