INSTALLATION
7. Safety
Only a qualified contractor should carry out installation, commis-
sioning, maintenance and repair of the appliance.
7.1 General safety instructions
We guarantee trouble-free function and operational reliability only
if original accessories and spare parts intended for the appliance
are used.
7.2 Instructions, standards and regulations
Note
Observe all applicable national and regional regulations
and instructions.
7.3 Operation of the appliance in buildings with
combustion equipment
If the building contains combustion equipment (tiled stoves, fire-
places, etc.), the responsible flue gas inspector must be consulted
in the planning phase. The flue gas inspector assesses whether all
statutory regulations are being observed. Here, a differentiation
is made between balanced and open flue combustion equipment.
For simultaneous operation of combustion equipment and a me-
chanical ventilation system, we recommend choosing approved
room sealed combustion equipment (in Germany, DIBt approval).
7.3.1 Room sealed combustion equipment
In conjunction with room sealed combustion equipment, no addi-
tional precautions are generally required. Assessment is carried
out by the flue gas inspector.
7.3.2 Open flue combustion equipment
!
WARNING INJURY
If open flue combustion equipment is operated with the
mechanical ventilation system, tested safety equipment
must be installed. The combustion equipment must also
have a separate combustion air supply.
With open flue combustion equipment, a differentiation must be
made between alternate and simultaneous operation of the ven-
tilation system and combustion equipment.
Alternate operation
Operation on alternate sides means that, when the combustion
equipment is commissioned, the mechanical ventilation system is
switched off and/or cannot be started.
Simultaneous operation
!
WARNING INJURY
To prevent any flue gas escaping into the installation
room, it is necessary to ensure that sufficient combustion
air is supplied or that the negative pressure in room
where the stove is installed is not greater than 4 Pa.
Tested safety equipment must be installed to monitor the
chimney draught (differential pressure monitoring) and
to switch off the ventilation unit in the event of a fault.
Connect the safety equipment according to the chapter "Installa-
tion / Electrical connection / Connection X15 / Connecting safety
equipment for stove/fireplace operation".
The equipment for differential pressure monitoring should fulfil
the following requirements:
- Monitoring of the differential pressure between the connec-
tion piece to the chimney and the room where the combus-
tion equipment is installed.
- Possibility of matching the shutdown value for the differential
pressure to the minimum draught requirement for the com-
bustion equipment.
- Floating contact to switch off ventilation.
- Optional connection of a temperature capturing device so
that differential pressure monitoring is only enabled when
the combustion equipment is in operation and so that un-
wanted shutdowns due to environmental influences can be
avoided.
Note
Differential pressure switches that use the pressure
differential between the outdoor air pressure and the
pressure in the room where the combustion equipment
is sited as a response criterion are not suitable.

Connect the safety equipment with a floating contact (see
chapter "Electrical connection / Connection X15").
The mechanical ventilation system is switched off when the safety
equipment responds.
Note
The maximum available external pressure (see chapter
"Specification / Data table") must not be exceeded.
