6.6.1 Using the cooktop extractor with a
fireplace which does not depend on
room air
Fireplaces depending on room air (e.g. gas, oil, wood or
coal-fired heaters, continuous-flow water heaters, instan-
taneous water heaters) draw in air from the room in which
they are installed and discharge the exhaust fumes to the
outside via an exhaust system (e.g. chimney).
When the cooktop extractor is used for exhaust air opera-
tion, it draws in air from the room it is installed in and from
neighbouring rooms. If there is insufficient air, an under-
pressure will occur. Toxic gases could be drawn out of the
chimney or extraction duct and back into the room.
