Prior To Installation - Gaggenau AW 250 Instrucciones De Montaje

The exactractor hood can be used in exhaust air
mode.
Always mount the extractor over the centre of the
hob.
Minimum distance between electric hob and
bottom edge of the extractor hood: 550mm.
The applicable regulations of the power supply
company and compliance of local and national
building regulations must be observed when
installing air extractor (overhead and table top
downdraught) in permanent dwellings.
The extractor hood must not be installed over a
solid fuel cooker – a potential fire hazard (e.g.
flying sparks) unless the cooker features a closed
non removable cover and all national regulations
are observed.
This limitation is not valid if you use gas cooking
top and gas cooker.
The smaller the gap between the extractor hood
and hotplates, the greater the likelihood that
droplets will form on the underside of the extractor
hood.
Additional information concerning gas cookers:
When installing gas hotplates, comply with the
relevant national statutory regulations (e.g. in
Germany – Technische Regeln Gasinstallation
TRGI).
Always comply with the currently valid regulations
and installation instructions supplied by gas
appliance manufacturer.
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 the lower edge of the
extractor hood: 650 mm Fig.2

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
ventilation 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 builing regulations)
Local authority regulations must be observed
when discharging air into smoke or exhaust air
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 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 (0,04mbar)
This can ben achieved if combustion air can flow
through non-lockable openings, e.g. in doors
windows and via the air-intake/exhaust-air wall box
or by the other technical measures, such as
reciprocal interlocking, etc.
If the air intake is inadeguate, there is a risk of
poisoning from combustion gases which are
drawn back into the room.
