4.
The exhaust duct should be as short and straight as possible. The diameter of the
exhaust hose should be at least 120/150 mm (look at chapter T
ECHNICAL
D
ATA
).
Otherwise, you have to expect increased noise and decreased performance of your
appliance.
5.
The proper maximum bending angle outwards is 120°.
6.
Use smooth tubes or flexible, non-inflammable exhaust hoses only.
7.
When the exhaust duct is connected horizontally, a minimum falling gradient of 1
cm/m or an inclination of 2° is required. Otherwise, condensate will get into the
motor of the hood.
8.
When an exhaust duct is used, the ending of the exhaust hose must be adjusted into
the direction of flow.
9.
If the exhaust duct passes through cool areas (e.g., an attic), a temperature gradient
may occur in the different parts of the exhaust duct so condensate will be generated.
Proper insulation of the corresponding parts of the exhaust duct will then be needed.
Equip such an exhaust duct with a condensate trap if need be.
10.
Depending on the model
the hood is equipped with one (top) or two (top, back)
outlets. The idle outlet is covered by a plastic cap. You can remove this cap by
turning it anticlockwise. Use the cap to cover the idle outlet.
2.2 Minimum distances
Strictly observe the minimum distance between the extractor hood and the
hob.
It is also absolutely necessary to observe the individual minimum distances
between hobs and extractor hoods; these are specified in the instruction
manual of your hob / oven / etc.

1.
The minimum distances do not represent the required total height, but a minimum
value generated by adding the height of the hob (floor ↔ hob) and the required
minimum distance of the hob to the extractor hood (hob ↔ extractor hood)
