2.7 INSTALLATION OF COAXIAL
DUCT (versions "BF")
2.7.1 Accessories 60/100 (fig. 6)
The 60/100 coaxial duct is supplied on
request in kit code 8084811.
The diagrams of fig. 6 illustrate some
examples of different types of discharge
modalities allowed and t he maximum
lengths that can be reached.
2.7.2 Diaphragm for 60/100
coaxial duct (fig. 6/a)
The boiler is supplied with a diaphragm of
87.5. Use the diaphragms according to the
indications of fig. 6/a.
2.7.3 Accessories 80/125 (fig. 7)
The 80 coaxial duct is supplied on request
in a kit code 8084830 complete with
assembly instructions.
With the curve supplied in the kit, the maxi-
mum horizontal length of the duct must be
no more than 6 metres.
The diagrams in fig. 7 show some examples
of the different types of 80/125 coaxial
discharge modalities.
2.8 INSTALLATION OF SEPARATE
DUCTS (versions “BF”) (fig. 7/a)
When installing, the provisions of the laws
in force must be adhered to, as well as cer-
tain practical suggestions:
– With aspiration directly from outside,
when the duct is longer than 1 metre, it
is advisable to insulate the said duct in
order to avoid the formation of dew on
the outside of the pipe when the weather
is particularly cold.
– With ducts with discharge positioned
outside the building, or in cold environ-
ments, insulation is necessary to avoid
difficulty in starting the burner. In these
cases, a condensation system on the
pipes must be provided for.
– If the pipe passes through inflammable
walls, insulate the stretch of the fumes
discharge pipe that passes through the
wall with rounded glass wool 30 mm
thick and with a density of 50 kg/m2.
The maximum total length, which is the
sum of lengths of the aspiration and
discharge pipes, is determined by the loss
of charge of the single accessories inser-
ted and must not result as more than 8.5

IMPORTANT:
– Each additional 90° curve installed reduces the available length by 1.0 metres.
– Each additional 45° curve installed reduces the available length by 0.80 metres.
– The insertion of the condensation collector (8) is obligatory in C32 discharge type.
– The insertion of the condensation collector (8) is obligatory in C42 discharge type.
