exceed 2.8 meter.
When the vertical extension
8086950 is used, the terminal part of the
pipe must always come out horizontally.
2.6.2 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. 7.
2.6.3 Coaxial duct outlet
on the roof
The roof discharge terminal L. 1285 cannot
be shortened and when positioning the tile,
the minimum distance from the discharge
head terminal must not be less than 600
mm (fig. 8).
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. 9.
It is possible to insert up to a maximum of
three extensions and reach a maximum
rectilinear distance of 3.7 meter.
Should it be necessary to make two chan-
ges of direction in the pipe development,
the maximum length of the pipe must not
exceed 2 meter.

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, inclu-
ding 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 combustion 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.
