The extracted air is normally vented vertically.

The extracted air can vented through the wall
units and the loft floor to the roof ridge.
If there is a conduit under the wall units, the ex-

traction duct can be routed so that the extracted
air can be vented horizontally through the wall.
Recirculation mode
If you do not have a direct extraction vent to the out-
side; the hood can also work in recirculation mode
(i.e. without an extraction vent to the outside; the
filtered air is released back into the room). In this
case, an activated carbon filter mat as described
"Installing the activated carbon filter mat for
under
recirculation mode"
, must be used.
Activated carbon filter mat is not supplied. You can
order the carbon filter mat from your dealer or in our
online accessories shop, www.bomann-germany.de.
Use the reference number found under
Data".
