2.5. 1 Emptying the system (fig. 4)
Use the drain tap to empty the system (5
fig. 4). Turn off the boiler before doing this.
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 boilers with natural draught
in collective pipes (type B) and those for boi-
lers 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
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 different types of discharge
modalities allowed and the maximum
lengths that can be reached.
2.7.2 Diaphragm for 60/100
coaxial duct (fig. 5/a)
The boiler is supplied with a diaphragm of
ø 79. Use the diaphragms according to the
indications of fig. 5/a.
For discharge types C12-C42, use the diaphragms supplied with the boiler ø 79.0 only when the
length of the coaxial duct is less than 1 metre.
For discharge types C32, use the following diaphragms according to the length of the duct and
without additional curves ø 79 in this mode:

L max = 2,5 m
* Minimum length of duct L = 1.3 m.
x + y = max 5,0 m per vers. "20"
x + y = max 3,5 m per vers. "25"
x + y = max 3,0 m per vers. "30-35"
IMPORTANT:
– Each additional 90° curve
installed reduces the availa-
ble length by 1.0 metres.
– Each additional 45° curve
installed reduces the availa-
ble length by 0.50 metres.
- The insertion of the conden-
sation collector (8) is obliga-
tory for vertical stretches of
more than 1.3 metres.
