NEFF D72F58N0GB, Installation Instructions Manual

13

Prior to installation, always follow the

instructions and warnings in the chapter
entitled ”Safety instructions”!

Exhaust-air mode

The exhaust air is conveyed upwards via a

ventilation shaft or directly through the outer
wall to the exterior.

NOTE: 

The exhaust air must not be conveyed

into a functioning smoke or exhaust gas flue or
into a shaft which is used to ventilate 
installation rooms which contain heating 
appliances.

Before conveying the exhaust air into a

non-functioning smoke or exhaust gas flue,
obtain the consent of the appropriate heating
engineer.

Discharge exhaust air in accordance with

the official and statutory regulations (e.g.
regional building laws).

If the exhaust air is conveyed through the

outer wall, a telescopic wall box should be
used.

To ensure optimum performance, the
extractor hood requires:

– a short, straight exhaust air pipe and
– the largest possible pipe diameter.

If pipe bends cannot be avoided, ensure

the largest possible radii. 

NOTE: 

If long, rough exhaust air pipes, a lot of

pipe bends or pipe diameters less than 
150 mm are used, the air capacity will be less
than optimum and there will be an increase in
noise.

Use only pipes or hoses made of non-

combustible material for installation of the
exhaust air duct.

The manufacturer of the extractor hoods is

not responsible for complaints which can be
attributed to planning and design of the
pipework.

Connecting pipes

The diameter of the exhaust air pipes

should not be less than 150 mm.

Round pipes:

We recommend an inner diameter of 
150 mm, however at least 120 mm.

Flat ducts

must have the same inner cross-

section as round pipes.
There should be no sharp bends.
Ø 150 mm approx. 177 cm

Ø 120 mm approx. 113 cm

If pipe diameters differ:

Use sealing strips.

Connection of 150 mm ø exhaust air pipe
(recommended size)

Attach exhaust air pipe

directly to the air-pipe
connector and seal
appropriately. If using an
aluminium pipe, smooth the
connection area beforehand.

Connection of 120 mm ø exhaust air pipe

Attach reducing

connector directly to the air-
pipe connector.

Attach exhaust air pipe to

the reducing connector.

Seal both joints

appropriately.
