For discharge types C32, use the following diaphragm ø 87.5 according to the length of the duct
and without additional curves:

ped, install an adequate filter on the gas pipe.
2.5 SYSTEM FILLING
Filling of the boiler and the system is done by
the system filling (fig. 24/a).
The charge pressure, with the system cold,
must be between
1 and 1.5 bar . Filling
must be done slowly so as to allow any air
bubbles to be bled off through the air valves.
2.5.1 Emptying the system (fig. 4/b)
To drain the system, turn off the boiler and
to loosen with one key from 13 the appro-
priate download of some turns (fig. 4/b).
2.6 FLUES/CHIMNEYS
A chimney or flue for the evacuation of the
combustion products into the atmosphere
must correspond to the requisites prescri-
bed by the laws in force. In particular, the
specific prescriptions of law relative to boi-
lers with natural draught in collective pipes
(type B) and those for boilers with forced
draught (type C) must be respected.
2.6.1 Ducting of existing chimneys
To recover or duct existing chimneys, ducts
declared suitable for the purpose by the
manufacturer must be used, and the instal-
lation and use modalities indicated by the
said manufacturer must also be followed
as well as the prescriptions of Standard
UNI 10845.
2.7 INSTALLATION OF COAXIAL
DUCT (versions "BF")
2.7.1 Accessories 60/100 (fig. 5)
The 60/100 coaxial duct is supplied on
request in kit code 8084811. The diagrams
of fig. 5 illustrate some examples of diffe-
rent types of discharge modalities allowed
and the maximum lengths that can be rea-
ched.
2.7.2 Diaphragm for 60/100
coaxial duct (fig. 5/a)
The boiler is supplied with a diaphragm of
ø 87.5. Use the diaphragms according to
the indications of fig. 5/a.

IMPORTANT:
– Each additional 90°
curve installed reduces
the available length by
1.0 metres.
– Each additional 45°
curve installed reduces
the available length by
0.50 metres.
- The inser tion of the
condensation collector
(8) is obligatory for ver-
tical stretches of more
than 1.3 metres.
Fig. 5/a
For discharge types C12-C42, use the diaphragm ø 87.5 only when the length of the coaxial duct
is less than 1 metre.
