5. 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 TECHNICAL DATA).
Otherwise you have to expect increased noise and decreased performance of your
appliance.
6. The proper maximum bending angle outwards is 120
0
.
7. Use smooth tubes or flexible, non-inflammable exhaust hoses only.
8. When the exhaust duct is connected horizontally, a minimum falling gradient of
1 cm/m or an inclination of 2
0
is required. Otherwise condensate will get into the
motor of the hood.
9. When an exhaust duct is used, the ending of the exhaust hose must be adjusted
into the direction of flow.
10. 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.
11. Depending on model, the hood is equipped with one (top) or two (top, back)
outlets.
12. 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.
