general
the discharge
The discharge may under no circumstances be connected to
a duct that is also used for other purposes. Bear in mind the
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 against
the entry of rain, leaves and the like by a grating. The
passage of the discharge may not be restricted by more than
20% by the wall grating.
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 installation pipes (for gas, water, etc.)
present.
The discharge stump has a diameter of 125 mm. It is best if
the discharge pipe also has this diameter.
electrical connection
The mains power supply must correspond to the rating
indicated on the plate situated inside the hood. If provided
with a plug connect the hood to a socket in compliance with
current regulations and positioned in an accessible area.
