For the installer
When used as an extractor unit, the hood must be fitted with a
120mm diameter hose (HE 3160: Ø 120-110mm).
Attention: The hose is not supplied and must be purchased
separately.
When installing the hood, make sure you respect the following
minimum distance from the top edge of the cooking hob/ring
surfaces:
electric cookers
600 mm
gas cookers
700 mm
If the instructions for installation for the gas hob specify a greater
distance, this must be adhered to.
The national standard on fuel-burning systems specifies a maximum
depression of 0.04 bar in such rooms.
The air outlet must not be connected to chimney flues or combustion
gas ducts. The air outlet must under no circumstances be connected
to ventilation ducts for rooms in which fuel-burning appliances are
installed.
The air outlet installation must comply with the regulations laid down
by the relevant authorities.
When the unit is used in its extractor version, a sufficiently large
ventilation hole must be provided, with dimensions that are
approximately the same as the outlet hole.
National and regional building regulations impose a number of
restrictions on using hoods and fuel-burning appliances connected to
a chimney, such as coal or oil room-heaters and gas fires, in the
same room.
Hoods can only be used safely with appliances connected to a
chimney if the room and/or flat (air/environment combination) is
ventilated from outside using a suitable ventilation hole approximately
500-600 cm

large to avoid the possibility of a depression being
created during operation of the hood.
If you have any doubts, contact the relevant controlling authority or
building inspectors office.
Since the rule for rooms with fuel burning appliances is outlet hole of
the same size as the ventilation hole, a hole of 500-600 cm
