7. Safety
only a qualified contractor should carry out installation, com-
missioning, 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.
when operating the appliance, a functioning inflow of outdoor
air must be ensured at all times. This can be achieved with air
apertures in the external walls.
WARNING Burns
LA 60 UB , LA 60 AB : To ensure that the appliances
installed in the building comply with fire protection
requirements, a fire protection expert must be con-
sulted at the design stage.
7.2 Instructions, standards and regulations
WARNING Burns
In connection with the fire prevention regulations
concerning the installation of ventilation systems,
observe all country-specific regulations and re-
quirements. In Germany, these are particularly the
building regulation guideline on fire prevention re-
quirements of ventilation systems in its applicable
version.
Note
observe all applicable national and regional regula-
tions and instructions.
7.3 Operation of the appliance in buildings
with combustion equipment
The term "combustion equipment" used below includes, for
example, tiled stoves, fireplaces and equipment with gas com-
bustion.

WARNING Injury
Ventilation units can generate negative pressure in
the dwelling. If combustion equipment is operating
at the same time, combustion exhaust gases can
penetrate the combustion equipment installation
room. It is therefore important to observe a number
of points for simultaneous operation of a ventilation
unit and combustion equipment.
The engineering, installation and operation of the ventilation
unit and combustion equipment must be carried out in accord-
ance with national and regional regulations.
7.3.1 Planning safety measures
Together with the relevant authorities, engineers plan the safe-
ty measures that are required for simultaneous operation of a
ventilation unit and combustion equipment.
Alternate operation
Alternate operation means that, when the combustion equip-
ment is commissioned, the mechanical ventilation system is
switched off and/or cannot be started. Alternate operation
must be ensured by appropriate measures, e.g. automatically
enforced shutdown of the ventilation unit.
Simultaneous operation
For simultaneous operation of combustion equipment and a
mechanical ventilation system, we recommend choosing ap-
proved room sealed combustion equipment (in Germany, with
dIBt approval).
If open flue combustion equipment is operated in the dwell-
ing at the same time as a ventilation unit, combustion exhaust
gases must be prevented from penetrating the home as a re-
sult of possible negative pressure in the room.
The ventilation unit may only be operated in combination with
intrinsically safe combustion equipment. This combustion
equipment has, for example, a draught hood or an exhaust
gas monitor and is permitted to be operated in conjunction
with ventilation units. Alternatively, external, tested safety
equipment can be connected to monitor the operation of the
combustion equipment. For example, you can install differen-
tial pressure monitoring to monitor the chimney draught and
to switch off the ventilation unit in the event of a fault.
The equipment for differential pressure monitoring must fulfil
the following requirements:
- Monitoring of the differential pressure between the con-
nection piece to the chimney and the combustion equip-
ment installation room
- Possibility of matching the shutdown value for the differ-
ential pressure to the minimum draught requirement for
the combustion equipment
- Floating contact to switch off the ventilation function
- 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 prevented
Note
differential pressure switches that use the pressure
differential between the outdoor air pressure and the
pressure in the combustion equipment installation
room as a response criterion are not suitable.
Note
we recommend installing and regularly maintain-
ing a carbon monoxide detector in accordance with
eN 50291 for operation of any combustion equipment.
