necessary for each type of installation are
given in fig. 14.
2.8.2 Roof outlet separate ducts
The roof outlet terminal L. 1390 cannot be
shortened and in the positioning of the tile
the distance from the discharge outlet of
the terminal must not be less than 700
mm (fig. 15).
The accessories necessary for this type of
discharge and some of the other type of
systems that it is possible to use are
shown in fig. 16.
By utilising the doubler fitting (7 fig. 16) it is
possible to have a concentric discharge. In
these cases, during assembly, it is neces-
sary to get the washer in silicon used on
the reduction of the terminal (5 fig. 17) to
be substituted with the doubler and place it
in the housing of the doubler.
For this type of discharge the sum of the
maximum development allowed of the
ducts must not be greater than 8.00 mm
