For the installer
When used as an extractor unit, the hood must be fitted with a 1 0mm diameter
hose.
When installing the hood, make sure you respect the following minimum
distance from the top edge of the cooking hob/ring surfaces:
electric cookers 500 mm
gas cookers 650 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 local authorities.
When the unit is used in its extractor version, a sufficiently large ventilation hole
must be provided, with dimensions that are approximately 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 cm2 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
inspectors 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 cm2, which is to say a larger hole,
could reduce the performance of the extractor hood.
If the hood is used in its recirculation mode, 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:
The ducting must be fire retardent, 1 0mm in diameter and the length should be
no more than:
