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.
