2. Insert the air duct in the wall. For ease of installation use the mounting wedges included in the delivery set.
The air duct end must protrude for the distance A that enables installation of the outer ventilation hood. The overall dimensions of
the outer ventilation hood, the outside protrusion length of the air duct A and the mounting sequence of the hood are stated in its
installation instruction.

Fill the gaps between the wall
and the hole with a mounting

Install the air duct with the minimum slope of 3 mm downwards
from the outer wall side.
The air duct can be cut by calculating preliminary the required
length or after fixing the air duct on the wall (in this case, it is
necessary to have access to the outside part of the wall).
3. Install the outer ventilation hood. The mounting sequence of the outer ventilation hood is described in the installation instruction for
the ventilation hood.
