Safety warnings
For the installer
• When used as an extractor unit, the hood must
be fitted with a 120mm diameter duct.
Attention: The duct 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
The hood can be installed above these heights
but for optimum performance it should be
installed at the distance quoted for the
appropriate heat source.
• 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
authorities.
• When the unit is used in its extractor version, 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 filtering function, 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 extractor function,
the following rules must be followed to obtain
optimal operation:
— short and straight outlet ducting
— keep bends in outlet ducting to a minimum
— never install the ducts with an acute angle,
they must always follow a gentle curve.
— keep the duct as large as possible
(preferably the same diameter as the
outlet hole).
• Failure to observe these basic instructions will
drastically reduce the performance and increase
the noise levels of the extractor hood.
