2.8.1
Separate pipe accessories
Kit code 8093000 is supplied for this pur-
pose (fig. 13). The sectored diaphragm is to
be used according to the maximum head
loss allowed in both pipes, as given in fig.
13/a. The complete range of accessories
necessary for satisfying all installation requi-
rements is reported in fig. 14.
2.8.2
Separate-pipes
roof outlet
The roof outlet terminal L. 1390 cannot be
shortened and when positioning the tile, the
minimum distance from the discharge head
terminal must not be less than 700 mm
(fig. 15). The accessories to be used for this
type of installation and some of the connec-
ting systems that may be adopted are illu-
strated in fig. 16.
There is the possibility of doubling the air-
intake and smoke-outlet pipes and then brin-
ging them back together again so as to
obtain a concentric discharge by using the
doubler fitting (7 fig. 16).
