1.7 IMMERGAS FLUE SYSTEMS.
Immergas supplies various solutions separately
ES
from the boiler regarding the installation of air
intake terminals and flue extraction, which are
fundamental for boiler operation.
PT
Important: The boiler must only be installed
together with an original Immergas air intake
and flue gas exhaust system. This system can be
identified by an identification mark and special
GR
distinctive marking bearing the note: "not for
condensing boilers".
The flue exhaust pipes must not be in contact with
PL
or be near to flammable materials. Moreover,
they must not pass through buildings or walls
made of flammable material.
See following paragraphs for the detailed descrip-
TR
tion of the kits available
Positioning of double lip seals. For correct
positioning of lip seals on elbows and exten-
CZ
sions, follow the direction of assembly given in
figure (Fig. 1-9).
• Resistance factors and equivalent lengths. Each
SI
flue extraction system component has a Resist-
ance Factor based on experimental tests and
specified in the table below. The resistance fac-
tor for individual components is independent
HU
from the type of boiler on which it is installed
or the actual dimensions. It is, however, condi-
tioned by the temperature of the fluids that pass
through the pipe and therefore varies according
RU
to applications for air intake or flue exhaust.
Each single component has a resistance cor-
responding to a certain length in metres of pipe
of the same diameter; the so-called equivalent
RO
length, obtained from the ration between the
relative Resistance Factors. All boilers have an
experimentally obtainable maximum Resistance
Factor equal to 100. The maximum Resistance
IE
Factor allowed corresponds to the resistance
encountered with the maximum allowed pipe
length for each type of Terminal Kit. This
information enables calculations to be made
SK
in order to verify the possibility of various
configurations of flue extraction systems.

1.8 OUTDOOR INSTALLATION IN
PARTIALLY PROTECTED AREA.
N.B.: a partially protected area is one in which the
appliance is not exposed to the direct action of the
weather (rain, snow, hail, etc.).
• Configuration type B, open chamber and fan
assisted.
The relevant terminal must be used for this
configuration (present in the intake kit for the
installation in question), which must be placed
on the central hole of the boiler (Fig. 1-12). Air
intake takes place directly from the environment
in which the boiler is installed and flue exhaust
in individual flue or to the outside.
In this configuration the boiler is classified as
type B .
22
With this configuration:
- air intake takes place directly from the environ-
ment in which the boiler is installed and only
functions in permanently ventilated rooms;
- the flue exhaust must be connected to its own
individual flue or channelled directly into the
external atmosphere.
The technical regulations in force must be
respected.
Diaphragm installation. For correct functioning
of the boiler configured with direct air intake, it
is necessary to install a diaphragm on the outlet
of the sealed chamber and before the diaphragm
exhaust pipe Ø 41.5 (Fig. 1-14).
• Cover kit assembly (Fig. 1-11). Remove the
two plugs and the gaskets present from the
two lateral holes with respect to the central
one. Now cover the left intake hole using the
relevant plate, fixing it onto the right side us-
ing the two supplied screws. Install the Ø 80
outlet flange on the central hole of the boiler,
taking care to insert the gasket supplied with
the kit and tighten by means of the screws
provided. Install the upper cover, fixing it us-
ing the 4 screws present in the kit, positioning
the relevant gaskets. Engage the 90° Ø 80 bend
with the male end (smooth) in the female end
(with lip seal) of the Ø 80 flange unit until it
stops. Introduce the gasket, making it run along
the bend. Fix it using the sheet steel plate and
tighten by means of the straps present in the
kit, making sure to block the 4 gasket flaps. Fit
the male end (smooth) of the exhaust terminal
into the female end of the bend 90° Ø 80, mak-
ing sure that the relevant wall sealing plate is
already fitted; this will ensure hold and joining
of the elements making up the kit.

• Coupling of extension pipes. To install push-
fitting extensions with other elements of the
flue extraction elements assembly, proceed as
follows: Install the pipe or elbow with the male
side (smooth) in the female section (with lip
seal) to the stop on the previously installed
element. This will ensure sealing efficiency of
the coupling.
Max. length of exhaust duct. The flue pipe
(vertical or horizontal) can be extended to a
max. length of 12 m straight route, using insulated
pipes (Fig. 1-31). To prevent problems of fume
condensate in the exhaust pipe Ø 80, due to fume
cooling through the wall, the length of the pipe
(not insulated) must be limited to just 5 m.
Example of installation with direct vertical
terminal in partially protected location. When
the vertical terminal for direct discharge of
combustion fumes is used, a minimum gap of
300 mm must be left between the terminal and
the balcony above. The height A B (always with
respect to the balcony above), must be equal to
or greater than 2000 mm (Fig. 1-13).
• Configuration without cover kit (boiler
type C).
By leaving the side plugs fitted, it is possible
to install the appliance externally, in partially
covered places, without the cover kit. Installation
takes place using the Ø 60/100 and Ø 80/125
concentric horizontal intake/ exhaust kits. Refer
to the paragraph relative to indoor installation.
In this configuration the top cover kit guarantees
additional protection for the boiler. It is recom-
mended but not compulsory.
