The maximum exhaust air duct length with a fan is 6 m.
Q
Q
The minimum cross-section of the air ducts must
be 176 cm², which equates to a round pipe with
a diameter of 150 mm or the BORA Ecotube duct
system.
Q
Q
For the ducting, only use stable duct elements with
smooth pipe interiors. Do not use flexible or fabric
tubes.

6.9 Operating the cooktop extractor
with a fireplace that depends on
the air in the room
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.
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.
6.8.2 Connect the duct system to the
device.
