Installation
The cooker hood is only intended to be installed over a hob with no more than
four hob elements.
There must be a safety distance between the hotplate of the cooking pot on the
hob and the bottom part of the cooker hood:
The distance must be between 65 – 75 cm. For gas appliances, the distance must
be at least 65 cm. If the installation instructions for the gas cooker specify
a greater distance, this distance must be taken into consideration.
Selecting the fume outlet You can operate the cooker hood in two modes:
Extraction mode
WARNING:
- The extracted air may not be vented into a flue which is used for the waste gas from appliances that are powered by gas or other fuels.
- When venting the extracted air, comply with the regulations of the relevant local authorities.
The hood has an upper air outlet to vent cooking odors to the outside.
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 extraction 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 outside; 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 as described under “Installing the activated carbon filter for
recirculation mode”, must be used. Activated carbon filters are not supplied.
You can order the carbon filter from your dealer or in our online accessories
shop, www.bomann-germany.de. To order, use the
reference number found under “Technical Data”.
