For the installer
When used as an extractor unit, the hood must e fitted with a hose
having prefera ly the same diameter as the outlet hole.
Only 5708 D: this model is equipped with two outlet hole. 2 hoses
are therefore necessary for discharging the fumes.
When installing the hood, make sure you respect the following
minimum distance from the top edge of the cooking hob/ring
surfaces:
electric cookers 650 mm
models (CH)DL 4150-HL 4150-DL6250 only 600 mm
gas cookers 700 mm
The hood can e installed a ove these heights ut for optimum
performance it should e installed at the distance quoted for the
appropriate heat source.
The national standard on fuel- urning systems specifies a maxi-
mum depression of 0.04 ar in such rooms.
The air outlet must not e connected to chimney flues or com us-
tion gas ducts. The air outlet must under no circumstances e
connected to ventilation ducts for rooms in which fuel- urning
appliances are installed.
The air outlet installation must comply with the regulations laid down
y the relevant authorities.
When the unit is used in its extractor version, a sufficiently large
ventilation hole must e provided, with dimensions that are
approximately the same as the outlet hole.
National and regional uilding regulations impose a num er of
restrictions on using hoods and fuel- urning appliances connected
to a chimney, such as coal or oil room-heaters and gas fires, in the
same room.
Hoods can only e used safely with appliances connected to a
chimney if the room and/or flat (air/environment com ination) is
ventilated from outside using a suita le ventilation hole approxi-
mately 500-600 cm2 large to avoid the possi ility of a depression
eing created during operation of the hood.
If you have any dou ts, contact the relevant controlling authority or
uilding inspectors office.
Since the rule for rooms with fuel urning 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 a ove conditions without the need for any of the
