Prior To Installation - Gaggenau AW 482 Instrucciones De Montaje

Only one side of the extractor hood may be
installed next to a high-sided unit or high wall. Gap
at least 50 mm.
Minimum distance on gas hotplates between the
upper edge of the trivet and lower edge of the
extractor hood: 650 mm, Fig. 2.
Recommendation 700 mm

Prior to installation

Exhaust-air mode
The exhaust air is discharged upwards through a
ventilation shaft or directly through the outside wall
into the open.
Exhaust air should neither be directed into a smoke
or exhaust flue that is currently used for other
purposes, nor into a shaft that is used for
ventilating rooms in which stoves or fireplaces are
also located.
Exhaust air may be discharged in accordance with
official and statutory regulations only (e.g. national
building regulations).
Local authority regulations must be observed when
discharging air into smoke or exhaust flues that are
not otherwise in use.
When the extractor hood is operated in exhaust-
air mode simultaneously with a different burner
which also makes use of the same chimney (such
as gas, oil or coal-fired heaters, continuous-flow
heaters, hot-water boilers) care must be taken to
ensure that there is an adequate supply of fresh
air which will be needed by the burner for
combustion.
Safe operation is possible provided that the
underpressure in the room where the burner is
installed does not exceed 4 Pa (0.04 mbar).
This can be achieved if combustion air can flow
through non-lockable openings, e.g. in doors,
windows and via the air-intake/exhaust-air wall box
8
or by other technical measures, such as reciprocal
interlocking, etc.
If the air intake is inadequate, there is a risk of
poisoning from combustion gases which are
drawn back into the room.
An air-intake/exhaust-air wall box by itself is no
guarantee that the limiting value will not be
exceeded.
Note: When assessing the overall requirement, the
combined ventilation system for the entire house-
hold must be taken into consideration. This rule
does not apply to the use of cooking appliances,
such as hobs and ovens.
Unrestricted operation is possible if the extractor
hood is used in recirculating mode – with activated
carbon filter.
If the exhaust air is going to be discharged into
the open, a telescopic wall box should be fitted into
the outside wall.
For optimum extractor hood efficiency:
•
Short, smooth air exhaust pipe.
•
As few bends in the pipe as possible.
•
Diameter of pipe to be as large as
possible and no tight bends in pipe.
•
If long, rough exhaust-air pipes, many pipe
bends or smaller pipe diameters are used,
the air extraction rate will no longer be at an
optimum level and there will be an increase
in noise.
•
Round pipes:
We recommend
Internal diameter: 150 mm (at least 120 mm).
•
Flat ducts must have an internal cross-section
that equates to that of round pipes.
There should be no sharp bends.
l 120 mm approx. 113 cm
l 150 mm approx. 177 cm
•
If pipes have different diameters:
Insert sealing strip.
•
For exhaust-air mode, ensure that there is an
adequate supply of fresh air.
Connecting a l 150 mm exhaust-air pipe:
•
Mount the pipe directly onto the air outlet on
the hood.
Connecting a l 120 mm exhaust-air pipe:
•
Place the reducing connecting piece onto the
air connecting piece – Fig. 3 – and fasten the
exhaust pipe to it.
