en Operating modes
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
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 air recirculation
mode, you must install an odour filter.
The different options for operating the
appliance in air circulation mode can
be found in our catalogue. Alternatively,
ask your dealer. The required accessor-
ies are available from specialist retail-
ers, from our after-sales service or from
the online shop.
