Installation with exhaust air to the outside
Note: Observe the safety instructions for operating the unit when the air is
discharged to the outside. If the cooker hood is in operation at the same time
as an appliance that draws its energy from a source other than electricity, the
negative pressure in the room must not exceed 4 Pa (4 x 10-5 bar).
• The extracted air is led to the outside via the exhaust air duct.
• For this purpose, your house must have an exhaust air shaft or an exhaust air
duct to the outside.
• If the extractor hood is used for exhaust air and chimney-dependent firing
systems (e.g. coal stoves) are operated at the same time, an adequate supply
of fresh air must be guaranteed in the room in which the extractor hood is
installed.
• In any case, contact your responsible chimney sweep.
• If there is no permanently installed exhaust air pipe or no separate exhaust air
shaft, you must switch the cooker hood to recirculation mode.
Installing the exhaust air hose
In the version with exhaust air to the outside, the vapours are extracted via an
exhaust air hose attached to the connection ring.
• The diameter of the exhaust hose must match the diameter of the connection
ring.
• The exhaust air hose must not be routed through a shaft together with gas
pipes, hot air pipes etc.
• Route the exhaust hose as straight as possible away from the hood; the
maximum permissible outward bend is 120°.
• If a smoke damper is used or planned, check that it opens and closes freely
after installing the exhaust hose.
• The cooker hood can be equipped with one (top) or two (top and rear)
exhaust openings. As a rule, the hood is initially equipped for use of the upper
extractor opening as a cooker hood.
• The openings that are not needed are covered with a plastic cover. This
plastic cover can be easily removed by turning it anticlockwise and optionally
attached to another opening that is not needed.
Use of the cooker hood as an exhaust hood (with exhaust air to the outside)
• If the cooker hood is equipped with an activated carbon filter at the factory,
this must be removed for exhaust air operation. This use only makes sense if
you operate your cooker hood in recirculation mode.
