4 Operating modes
4.1 Air extraction mode
The air which is drawn in is cleaned by the grease fil-
ters and conveyed to the exterior by a pipe system.
The air must not be discharged into a
flue that is used for exhausting fumes
from appliances burning gas or other
fuels (not applicable to appliances that
only discharge the air back into the
room).
¡
If the exhaust air is to be conveyed
into a non-functioning smoke or ex-
haust gas flue, you must obtain the
consent of the heating engineer re-
sponsible.
¡
If the exhaust air is conveyed
through the external wall, a tele-
scopic duct should be used.
4.2 Air recirculation mode
The air which is drawn in is cleaned by the grease fil-
ters and an odour filter, and conveyed back into the
room.
To bind odours in circulating-air mode,
you must install an odour filter. The dif-
ferent options for operating the appli-
ance in circulating-air mode can be
found in our catalogue. Alternatively,
ask your dealer. The required accessor-
ies are available from specialist retail-
ers, from customer service or from the
Online Shop.
