Given the substantial size of the holes to be made in the wall,
we recommended that suitable equipment (a core drill) be used,
together with a suction system to limit the amount of dust and
rubble.

CAUTION
The holes for channelling the inlet and outlet pipes
outside must be slightly inclined downwards, to
prevent any water coming in through the ducts.

WARNING
When making the holes for channelling the inlet and
outlet pipes outside, the majority of the material may
be expelled outside; it is therefore important to check
that it does not hit people or objects below as it falls.
To avoid damaging the external plastering as far as
possible, take extra care in the final stages of making
the hole.
m
CAUTION
The manufacturer is not responsible for any damage
to people, animals or objects following incorrect
installation of the air inlet and outlet system.
5.12.3 Fitting the air ducts
– Cut the pipe (1) so that M1 = space between the wall and the
elbow (A) + approximately 45 mm (insertion length of the pipe
(1) in the elbow (3))
– cut the pipe (2) so that M2 = 160 + wall thickness (B) + space
between the wall and the elbow (A) + approximately 60 mm
(insertion length of the pipe (2) in the elbow (3))
– insert the rings (4) inside the pipe (1), then the pipe (1) in the
elbow (3) and the assembled unit in the support (5)
– install the pipe (2), from the outside, until it is fully inserted
in the elbow (3).
