be covered, use Ø 80 pipes with insulation (see
insulated separator kit Ø 80/80 chapter).
N.B.: when installing the Ø 80 ducts, a section
clamp with pin must be installed every 3 metres.
Insulated separator kit Ø 80/80. Kit assembly
(Fig. 1-25): install ange (4) on the central hole
of the boiler, tting gasket (1) and tighten with
the at-tipped hex screws included in the kit.
Remove the at ange present in the lateral hole
with respect to the central one (according to
needs) and replace it with the ange (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
male side (smooth), and join bends (5) with the
male side (smooth) in the female side of ange
(3). Fit bend (11) with the male side (smooth)
into the female side of ange (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 (8 and 9) that ensure correct installation
between pipe and wall, then x the closing cap
(6) on the terminal (7). Join the exhaust pipe (10)
with the male side (smooth) in the female side
of the bend (11) to the end stop, ensuring that
the wall sealing plate (8) is already inserted for
correct installation between the pipe and ue.
• Coupling extension pipes and elbows.To snap-
t extensions with other elements of the fume
extraction elements, operate as follows: engage
the concentric pipe or elbow with the male
side (smooth) on the female section (with lip
seal) up to the stop on the previously installed
element. is will ensure sealing and joining
of the elements correctly.
• Insulation of separator terminal kit. Whenever
there are ue 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 ue 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. e
gures (Fig. 1-26 and 1-27) illustrate dierent
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 ange until it is taken up to stop on the
ue gas exhaust ange, a situation that takes
the two intake ue gas exhaust outlets to the
same height.
• Temperature loss in insulated ue 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. e gure (Fig. 1-27) illustrates
a typical insulation application in which the
intake pipe is short and the exhaust pipe is
very long (over 5 m). e 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. e
entire exhaust pipe, except the elbow leaving
the splitter is insulated to reduce heat loss from
the pipe, thus preventing the formation of ue
gas condensate.
N.B.: When installing the insulated pipes, a
section clamp with pin must be installed every
2 metres.
• Conguration type B, open chamber and fan
assisted.
When using type B installation conguration
indoors, it is compulsory to install the relative up-
per cover kit along with the fumes discharge kit.
e air intake comes directly from the area where
the boiler is installed and from the ue exhaust
in each single ue or directly from outdoors.
e boiler in this conguration, following the
assembly instructions stated in the par. 1.8 is
classied as type B.
With this conguration:
- air intake takes place directly from the environ-
ment in which the boiler is installed and only
functions in permanently ventilated rooms;
- the ue exhaust must be connected to its own
individual ue 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 nes, cement, etc.), which may be damag-
ing for the components of the appliance and
jeopardise functioning.
On installation indoors in type B conguration
it is mandatory to install the relevant top cover
kit along with the ue gas exhaust kit.
The technical regulations in force must be
respected.
e kit includes:
N°1 - Exhaust gasket (1)
N°1 - Flange seal (2)
N°1 - Female intake ange (3)
N°1 - Female exhaust ange (4)
N°1 - Bend 90° Ø 80 (5)
