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.
