For the installer
• When used as an extractor unit, the hood must be fitted with a
150mm diameter hose.
Should there already be a pipe of diameter 125 or 120 mm that ducts
to the outside through the walls, it is possible to use the 150/125-
120 mm reduction flange provided.
In this case the hood will be slightly noisier.
• When installing the hood, make sure you observe the follow-
ing minimum distance from the top edge of the cooking hob/
ring surfaces:
electric cookers
500 mm
gas cookers 650 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 mbar 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 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 approximately
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.
