1.26 DUCTING OF FLUES OR TECHNICAL
SLOTS
Ducting is an operation through which, via the introduction of
one or more relevant pipes, one achieves a system for the evacua-
t ion of the combu st ion pro duc t s of a gas appl ia nc e, made up f rom
the coupling of an existing or new ducting pipe with a chimney,
ue or technical slot (also in new buildings) (Fig. 40).
Ducting requires ducts declared to be suitable for the purpose by
the manufacturer, following the installation and user instruc-
tions, provided by the manufacturer and the requirements of the
regulations in force.
Immergas ducting systems
e Ø 60 rigid, Ø 50 and Ø 80 exible and Ø 80 rigid
“Green Range” ducting systems must only be used for
domestic use and with Immergas condensing boilers.
In any case, ducting operations must respect the provisions con-
tained in the standard and in current technical regulations; in
particular, the declaration of conformity must be compiled at the
end of work and on commissioning of the ducted system.
e instructions in the project or technical report must likewise
be followed, in cases provided for by the standard and current
technical regulations.
To guarantee reliability and operation over time of the ducting
system, make sure:
- it is used in average atmospheric and environmental condi-
tions, according to current regulations (absence of combustion
products, dusts or gases that can alter the normal thermophysi-
cal or chemical conditions; existence of temperatures coming
within the standard range of daily variation, etc.).
- Installation and maintenance must be performed according to
the indications supplied by the manufacturer included with the
“green range” ducting system chosen and in compliance with
the regulations in force.
- e maximum length specied by the manufacturer must be
respected; in this regard:
• e max. possible length of the Ø 60 rigid ducting vertical
section is equal to 22 m. is length is obtained considering
the complete Ø 80 exhaust terminal, 1 m of Ø 80 pipe in ex-
haust, two 90° Ø 80 bends at indoor unit outlet.
• e max. possible length of the Ø 80 exible ducting vertical
section is equal to 18 m. is length is obtained considering
the Ø 80 complete exhaust terminal, 1 m of Ø 80 pipe in ex-
haust, two 90° Ø 80 bends at indoor unit outlet for connecting
to the ducting system and two direction changes of the exi-
ble hose inside the chimney/technical slot.
• e max. possible length of the Ø 80 rigid ducting vertical
section is equal to 30 m. is length is obtained considering
the complete Ø 80 exhaust terminal, 1 m of Ø 80 pipe in ex-
haust, two 90° Ø 80 bends at indoor unit outlet.
You can also install an additional Ø 50 exible ducting
system the specications of which are found on the rele-
vant instructions sheet inside the kit.
