6.6 Installing the exhaust air version
(BFIA)
INFO
The state and regional laws and regulations
must be observed with regard to the exhaust
duct design. A sufficient air supply must be
ensured.
6.6.1 Operating the cooktop extractor with
a fireplace that depends on the air in
the room
Fireplaces that depend on the air in the room (e.g. gas,
oil, wood or coal-fired heaters, continuous-flow water
heaters, instantaneous water heaters) draw in air from
the room in which they are installed and release the
exhaust fumes into the outside air via an exhaust system
(e.g. chimney).
If the cooktop extractor is used in exhaust mode, it draws
in air from the room in which it is installed as well as from
neighbouring rooms. If there is insufficient air supply, low
pressure will occur. Toxic gases could be drawn out of the
chimney or extraction ducting and back into the room.

If simultaneously operating both a fireplace and the
cooktop extractor in the same room, ensure that:
Q
Q
the maximum low pressure is 4 Pa (4 x 10–5 bar);
Q
Q
a safety device (e.g. window contact switch, low
pressure warning device) is used to ensure that a
sufficient supply of fresh air is guaranteed;
Q
Q
the exhaust air is not be ducted into a chimney that
is used for exhaust gases of devices operated with
gas or other combustibles;
Q
Q
the installation is checked and approved by an
authorised certified engineer (e.g. heating engineer).
