2.7. 1 Installation of diaphragm
The diaphragm is normally supplied
together with boiler version "30 BF". See
fig. 9 for positioning.
ATTENTION: Install the diaphragm only
when the length of the ø 60/100 coaxial
pipe is less than 1 m.
2.7.2 Coaxial
duct accessories
The accessories to be used for this type of
installation and some of the connecting
systems that may be adopted are illustra-
ted in fig. 10.
With the pipe bend included in the kit, the
maximum length of the piping should not
exceed 3 m.
When the vertical extension
8086900 is used, the terminal part of the
pipe must always come out horizontally.
2.7.3 Positioning the
outlet terminals
The outlet terminals for forced-draught
appliances may be located in the external
perimeter walls of the building.
To provide some indications of possible solu-
tions, Table 1 gives the minimum distances
to be observed, with reference to the type
of building shown in fig. 10/a.
2.7.4 Coaxial duct outlet
on the roof
The roof discharge terminal L. 1284 cannot
be shortened and when positioning the tile,
the minimum distance from the discharge
head terminal must not be less than 600
mm (fig. 11).
The accessories to be used for this type of
installation and some of the connecting
systems that may be adopted are illustra-
ted in fig. 12.
It is possible to insert up to a maximum of
three extensions and reach a maximum
78

TABLE 1
Siting of terminal
A - below openable window
B - below ventilation opening
C - below eaves
D - below balcony (1)
E - from adjacent window
F - from adjacent ventilation opening
G - from horizontal or vertical soil or drain pipes (2)
H - from corner of building
I - from recess in building
L - from ground level or other treadable surface
M - between two terminals set vertically
N - between two terminals set horizontally
O - from a surface facing without openings or terminals
P - as above but with openings and terminals
1) Terminals below a practicable balcony must be located in such a way that the total path
of the smoke from its outlet point from the terminal to its outlet point from the external
perimeter of the balcony, including the height of possible railings, is not less than 2000
mm.
2) When siting terminals, where materials that may be subject to the action of the combu-
stion products are present in the vicinity, e.g., eaves, gutters and downspouts painted or
made of plastic material, projecting timberwork, etc., distances of not less than 1500 mm
must be adopted, unless adequate shielding is provided to guard these materials.
