AEG 825 D Ventilation Hood User Manual


 
25
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.
