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 cm2, 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 0).
Failure to observe these basic rules will drastically reduce
the performance and increase the noise levels of the extrac¬
tor hood.
