directions requested by the Norms and a
few practical considerations:
– With direct external suction, when the
duct is greater than 1 m in length, insu-
lation is recommended in order to avoid,
in particularly cold periods, the formation
of dew on the outside of the tubing.
– With discharge duct positioned on the
outside of the building, or in cold environ-
ments, insulation is necessary to avoid
starting failures of the burner. In such
cases, a system for the collection of con-
densation must organised.
– If a segment of the flue passes through
a flammable wall, this segment must be
insulated with a glass wool pipe insula-
tor 30 mm thick, with a density of 50
kg/m 3 .
The maximum total length obtained by
summing up the lengths of the suction and
discharge tubing is determined by the load
losses of the single fittings attached
(excluding the splitter) and must not be
greater than 9.00 mm H

O. For the load
losses of the fittings refer to Table 4.
3.8.1 Separate ducts accessories
For the realisation of this type of discharge
is supplied a kit cod. 8093000 (fig. 14).
The sector diaphragm in the kit, must be
used according to the maximum load loss
allowed in both ducts, as indicated in fig.
14/a. The complete range of accessories
necessary for each type of installation are
given in fig. 15.
3.8.2 Roof outlet separate ducts
The roof outlet terminal L. 1240 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. 16). 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. 17) 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. 16) 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 9.00 mm

gle fittings attached refer to Table 4.
