For the installer
• When used as an extractor unit, the hood must be fitted with a hose
having preferably the same diameter as the outlet hole.
Attention:
The hose is not supplied and must be purchased
separately.
• When installing the hood, make sure you observe the following
minimum distance from the top edge of the cooking hob/ring
surfaces:
electric cookers
650 mm
gas cookers
750 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 maxi-
mum depression of 0.04 mbar in such rooms.
• The air outlet must not be connected to chimney flues or combus-
tion 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 local authorities.
• When the unit is used in extraction mode, a sufficiently large
ventilation hole must be provided, with dimensions that are approxi-
mately 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 approxi-
mately 500-600 cm
2
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 inspector’s 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
2
,
which is to say a larger hole, could reduce the performance of the
extractor hood.
• If the hood is used in its recirculation mode, it will operate simply
and safely in the above conditions without the need for any of the
aforementioned measures.
• When the hood is used in its extraction mode, the following rules
must be followed to obtain optimal operation:
