1.19 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 evacuation of the
combustion products of a gas appliance, made up
from the coupling of an existing or new ducting
pipe with a chimney, ue or technical slot (also
in new buildings) (Fig. 31). Ducting requires
ducts declared to be suitable for the purpose by
the manufacturer, following the installation and
user instructions, provided by the manufacturer
and the requirements of the standards in force.
Immergas ducting system.
e Ø 60 rigid, Ø
80 exible and Ø80 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 contained 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. e system or components
of the system have a technical life complying with
current standards, provided that:
- it is used in average atmospheric and envi-
ronmental conditions, according to current
regulations, (absence of ue gas, dusts or gases
that can alter the normal thermophysical or
chemical conditions; existence of temperatures
coming within the standard range of daily
variation, etc.).
- Installation and maintenance must be per-
formed according to the indications supplied
by the manufacturer and in compliance with
the regulations in force.
- e maximum length speci ed by the manu-
facturer must be respected; in this regard:
- e max. possible length of the Ø 60 exible
ducting vertical section is equal to 22 m.
length is obtained considering the complete
Ø 80 exhaust terminal, 1m of Ø 80 pipe in
exhaust, two 90° Ø 80 bends at boiler outlet.
- e max. possible length of the Ø 80 exible
ducting vertical section is equal to 30 m.
is length is obtained considering the Ø80
complete exhaust terminal, 1m of Ø 80 pipe
in exhaust, two 90° Ø 80 bends at boiler outlet
for connecting to the ducting system and two
direction changes of the exible hose inside
the chimney/technical slot.
- e max. possible length of the Ø 80 exible
ducting vertical section is equal to 30 m.
length is obtained considering the complete
Ø 80 exhaust terminal, 1m of Ø 80 pipe in
exhaust, two 90° Ø 80 bends at boiler outlet.
You can also install an additional Ø50 exible
ducting system the speci cations of which are
found on the relevant instructions sheet inside
the kit.
1.20 CONFIGURATION TYPE B, OPEN
CHAMBER AND FAN ASSISTED FOR
INDOORS.
e appliance can be installed inside buildings
in or B mode; in this case, all technical rules
23 53
and national and local regulations in force, must
be complied with.
- Type B open chamber boilers must not be
installed in places where commercial, artisan
or industrial activities take place, which use
products that may develop volatile vapours or
substances (e.g. acid vapours, glues, paints, sol-
vents, combustibles, etc.), as well as dusts (e.g.
dust deriving from the working of wood, coal
nes, cement, etc.), which may be damaging for
the components of the appliance and jeopardise
functioning.

is
in rooms containing solid fuel heat generators
nor in rooms communicating with said rooms.
- Installation of appliances in B
guration is recommended in non-residential
premises and which are permanently ventilat-
ed.
For installation the cover kit must be used, re-
ferred to in Paragraph 1.13.
1.21 FLUE EXHAUST TO FLUE/CHIMNEY.
Flue exhaust does not necessarily have to be con-
nected to a branched type traditional ue.
exhaust, for boiler clots installed in C con guration,
is
can be connected to a special LAS type multiple ue.
For B con gurations, exhaust is only allowed into
23
individual chimney or directly into the external
atmosphere via a relevant terminal.
ues and the combined ues must also only be
connected to type C appliances of the same type
(condensation), having nominal heat inputs that do
not di er by more than 30% less with respect to the
maximum that can be attached and powered by the
same fuel. e thermo- uid dynamic features ( ue
ow rate, % of carbon dioxide, % humidity etc....) of
the appliances attached to the same multiple ues
or combined ues, must not di er by more than
10% with respect to the average boiler attached.
Multiple and combined ues must be specially
designed according to the calculation method and
requirements of the technical standards in force,
by a professionally quali ed company. Chimney
or ue sections for connection of the ue exhaust
pipe must comply with requisites of technical
standards in force.
