2. Installation Conditions and
Relevant Building Regulations
The stove must be installed in accordance with the
instructions and requirements stipulated by the re-
spective 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 installation surface is sufficient for the dimen-
sions and weight of the stove. If necessary, using a
floorplate to distribute the load can increase the load
bearing capacity.
If the stove will be operated as a room air dependent
stove, please ensure that the room it will be installed
in has a sufficient supply of combustion 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
ventilation systems and/or exhaust hoods
can cause negative pressure to build up
in the room where the stove is installed,
which can lead to problems such as flue
gas escaping from the stove.
If the stove will be operated as a room air
dependent stove, the negative pressure in
the room where the stove is installed is not
permitted to exceed 4 Pascal.
When operated as a direct vent stove,
the negative pressure in the room where
the stove is installed is not permitted to
exceed 8 Pascal (the ventilation system
designer specifies the air pressure in
Pascal units). We recommend setting the
ventilation system to a maximum negative
pressure of 4 Pascal.
NOTE!
To avoid negative pressure in the room
where the stove is installed, we recom-
mend either using a window contact switch
to lock exhaust hoods that guide the air to
the outside or ensuring that a sufficient
amount of air can flow into the room where
the stove is located.
4. Chimney Connection
The stove has to be connected to a suitable chimney
with a minimum effective chimney height of 4.50 m.
The exhaust/flue gas system temperature class
(chimney and flue gas pipe) 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 technical data con-
tained in the operating instructions (Part I) and the
section on “Connection of Multiple Devices in Direct
Vent Operation”. The chimney cross section should
correspond to the flue pipe cross section. If the ef-
fective 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 instruc-
tions (Part I). At output pressures higher than speci-
fied, the stove emissions increase, which puts a high
load on the stove and can lead to damage.
The stove has a maximum permissible output pres-
sure of 20 Pa. To limit the output pressure, a butterfly
valve (a) (Fig. 2) or output pressure limiter can be
used (only possible with room air dependent ope-
ration).
If a soot fire occurs in the chimney, the flue gas path
has to be checked for leaks and to ensure that it is
tightly sealed. If these requirements and values can-
not be complied with or if there are any doubts or
questions concerning the suitability of the chimney,
we recommend conducting a chimney calculation
according to EN 13384-1/2.
