discharge
The discharge should not be connected to a duct which is
also used for other purposes under any circumstances.
Bear in mind any local regulations concerning the ventilation
of gas appliances.
The discharge may pass straight through the wall to the
outside, provided that the wall opening is protected - by
means of a grating - against rain, leaves, and the like getting
in. The passage of the discharge may not be restricted by
the wall grating by more than 20%.
We advise the use of as large a discharge duct as possible.
A duct with a smaller diameter will have a low extraction
capacity and produce higher noise levels.
Bends produce resistance. Make sure that the duct has a
smooth run and has as few bends as possible. Draw the
flexible pipe out as far as possible.
Before starting to drill, check that there are no installed
pipes present.
The discharge stump has a diameter of 150 mm. It is best if
the discharge pipe also has this diameter.
A reducing piece (150 mm to 125 mm) is supplied with the
appliance for connection to a 125 mm discharge pipe.
transport protection device
The cooker hood comes with a transport protection device
that has to be removed before installation. Remove the 4
screws at the rear of the motor module (see fig.) and detach
the motor module from the cooker hood. Observe
