● 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 only
— keep the hose as large as possible (120 mm Ø min.).
● Failure to observe these basic rules will drastically reduce
the performance and increase the noise levels of the
extractor hood.
