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, flue or technical slot (also
in new buildings) (Fig. 1-26). 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.

The Ø 6

rigid and

Ø 8

flexible “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.  The  instructions  in  the  project
or technical report must likewise be followed, in
cases provided for by the standard and current
technical regulations. The system or components
of the system have a technical life complying with
current standards, provided that:
-  it is used in average atmospheric and environ-

mental conditions, according to current regula-
tions (absence of fumes, 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 provisions in force.

- The max. possible length of the

60 flexible

ducting vertical section is equal to 22 m. This
length is obtained considering the complete

80 exhaust terminal, 1m of

80 pipe in

exhaust, two 90°

80 bends at boiler outlet.

- The max. possible length of the

80 flexible

ducting vertical section is equal to 30 m. This

length is obtained considering the complete
exhaust terminal, 1m of

80 pipe in exhaust,

two 90°

80 bends at boiler outlet for connect-

ing to the ducting system and two direction
changes of the flexible hose inside the chimney/
technical slot.

- The maximum possible length of the

80 rigid

ducting vertical section is equal to 30 m. This
length is obtained considering the complete

80 exhaust terminal, 1m of

80 pipe in ex-

haust, two 90°

80 bends on the boiler outlet.

1.1

CONFIGURATION TYPE B, OPEN

CHAMBER AND FAN ASSISTED FOR
INDOORS.

The appliance can be installed inside buildings
in

or B

mode; in this case, all technical rules

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,
solvents,  combustibles,  etc.),  as  well  as  dusts
(e.g. dust deriving from the working of wood,
coal fines, cement, etc.), which may be harm-
ful  for  the  components  of  the  appliance  and
jeopardise operation.

- In B

and B

configuration, the boilers must

not be installed in bedrooms, bathrooms or in
studio flats.

- The installation of appliances in B

and B

con-

figurations are only recommended outdoors (in
a partially-protected place) or in places that
are not lived in and which are permanently
ventilated.

The suitable kit referred to in paragraph 1.11
must be used for installation.

1.18 FLUE GAS EXHAUST TO FLUE/

CHIMNEY.

Flue exhaust does not necessarily have to be
connected to a branched type traditional flue.
The flue exhaust, for boiler clots installed in C
configuration, can be connected to a special LAS

type multiple flue. For B configurations, exhaust
is only allowed into individual chimney or di-
rectly into the external atmosphere via a suitable
terminal. The multiple flues and the combined
flues must also only be connected to type C ap-
pliances of the same type (condensing), having
nominal heat inputs that do not differ by more
than 30% less with respect to the maximum that
can be attached and powered by the same fuel.
The  thermo-fluid  dynamic  features  (flue  flow
rate, % of carbon dioxide, % humidity etc....) of
the appliances attached to the same multiple flues
or combined flues, must not differ by more than
10% with respect to the average boiler attached.
Multiple and combined flues must be specially
designed  according  to  the  calculation  method
and  requirements  of  the  technical  standards
in force, by a professionally qualified company.
Chimney or flue sections for connection of the
flue exhaust pipe must comply with requisites of
technical standards in force.

1.19 FLUES, CHIMNEYS, CHIMNEY POTS

AND TERMINALS.

The flues, chimneys and chimney pots for the
evacuation of combustion products must be in
compliance with applicable standards. Chimneys
and roof-installed exhaust terminals must com-
ply with the outlet height and with the distance
from technical volumes set forth by the technical
standards in force.

Positioning the wall

ue exhaust terminals.

The

wall flue exhaust terminals must:

- be installed on external perimeter walls of the

building;

- be positioned according to the minimum dis-

tances specified in current technical standards.

Combustion products exhaust of natural
draught or fan assisted appliances in open-top
closed environments.

In spaces closed on all

sides with open tops (ventilation pits, court-
yards etc.), direct combustion product exhaust
is allowed for natural draught or fan assisted gas
appliances with a heat input range from 4 to 35
kW, provided the conditions as per the current
technical standards are respected.
