(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 -Technical Data-). 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
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.
(11) 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.
