Instructions, standards and regulations

Note
Observe all applicable national and regional regulations
and instructions.
WARNING Burns
In connection with the fire prevention regulations con-
cerning the installation of ventilation systems, observe
all country-specific regulations and requirements. In
Germany, these are particularly the building regulation
guideline on fire prevention requirements of ventilation
systems in its applicable version.
7.3 Operation of the appliance in buildings with
combustion equipment
The term "combustion equipment" used below includes, for exam-
ple, tiled stoves, fireplaces and equipment with gas combustion.
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
room where the combustion equipment is installed. It is
therefore important to observe a number of points for
simultaneous operation of a ventilation unit and com-
bustion equipment.
The engineering, installation and operation of the ventilation unit
and combustion equipment must be carried out in accordance with
national and regional regulations.
7.3.1 Planning safety measures
Together with the relevant authorities, engineers plan the safety
measures that are required for simultaneous operation of a ven-
tilation unit and combustion equipment.
Alternate operation
Alternate operation means that, when the combustion equipment
is started, 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.
