• 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 hose
— keep bends in outlet hose to a minimum
— never install the hoses with an acute angle, they must always follow a gentle curve.
— keep the hose 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.
