N.B.: when installing the Ø 80 ducts, a sec-
tion clamp with pin must be installed every 3
ES
metres.
Insulated separator kit Ø 80/80. Kit assembly
(Fig. 1-29): install flange (4) on the central hole
PT
of the boiler, fitting gasket (1) and tighten with
the flat-tipped hex screws included in the kit.
Remove the flat flange present in the lateral hole
with respect to the central one (according to
GR
needs) and replace it with the flange (3), position-
ing the gasket (2) already present in the boiler and
tighten using the supplied self-threading screws.
Insert and slide cap (6) onto bend (5) from the
PL
male side (smooth), and join bends (5) with the
male side (smooth) in the female side of flange
(3). Fit bend (11) with the male side (smooth)
TR into the female side of flange (4). Fit the male end
(smooth) of the intake terminal (7) up to the stop
on the female end of the bend (5), making sure
you have already inserted the wall sealing plates
CZ
(8 and 9) that ensure correct installation between
pipe and wall, then fix the closing cap (6) on the
terminal (7). Join the exhaust pipe (10) with the
male side (smooth) in the female side of the
SI
bend (11) to the end stop, ensuring that the wall
sealing plate (8) is already inserted for correct
installation between the pipe and flue.
• Coupling extension pipes and elbows.To snap-
HU
fit extensions with other elements of the fume
extraction elements, operate as follows: engage
the concentric pipe or elbow with the male
RU
side (smooth) on the female section (with lip
seal) up to the stop on the previously installed
element. This will ensure sealing and joining
of the elements correctly.

• I nsulation of separator terminal kit. Whenever
there are flue gas condensate problems in the
exhaust pipes or on the external surface of the
intake pipes, on request Immergas supplies

insulated intake-exhaust pipes. Insulation
may be necessary on the exhaust pipe, due to
excessive loss of temperature of the flue gas on
their route. Insulation may be necessary on
the intake pipe as the air entering (if very cold)
may cause the outside of the pipe to fall below
the dew point of the environmental air. The
figures (Fig. 1-30 and 1-31) illustrate different
applications of insulated pipes.
Insulated pipes are formed of Ø 80 internal
concentric pipe and a Ø 125 external pipe with
static air space. It is not technically possible to
start with both Ø 80 elbows insulated, as clear-
ances will not allow it. However starting with an
insulated elbow is possible by choosing either
the intake or exhaust pipe. When starting with
the insulated intake bend it must be engaged
on its flange until it is taken up to stop on the
flue gas exhaust flange, a situation that takes
the two intake flue gas exhaust outlets to the
same height.
• Temperature loss in insulated flue ducting.
To prevent problems of fume condensate in
the exhaust pipe Ø 80, due to fume cooling
through the wall, the length of the pipe must be
limited to 12 m. The figure (Fig. 1-31) illustrates
a typical insulation application in which the
intake pipe is short and the exhaust pipe is
very long (over 5 m). The entire intake pipe is
insulated to prevent moist air in the place where
the boiler is installed, in contact with the pipe
cooled by air entering from the outside. The
entire exhaust pipe, except the elbow leaving
the splitter is insulated to reduce heat loss from
the pipe, thus preventing the formation of flue
gas condensate.
N.B.: When installing the insulated pipes, a
section clamp with pin must be installed every
2 metres.

• Configuration type B, open chamber and fan
assisted.
When using type B installation configuration
indoors, it is compulsory to install the relative up-
per cover kit along with the fumes discharge kit.
The air intake comes directly from the area where
the boiler is installed and from the flue exhaust in
each single flue or directly from outdoors.
The boiler in this configuration, following the
assembly instructions stated in the par. 1.8 is
classified as type B.
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.
- 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 damag-
ing for the components of the appliance and
jeopardise functioning.
On installation indoors in type B configuration
it is mandatory to install the relevant top cover
kit along with the flue gas exhaust kit.
The technical regulations in force must be
respected.
