TECHNICAL DATA
• Insulated separator kit Ø 80/80.
Kit assembly (Fig. 27): 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), positioning 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 in-
stallation 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 extrac-
tion 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 sur-
face 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.
28 and 29) 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 clearances
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. 29) 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
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)
N°1 - Pipe closure cap (6)
N°1 - Intake terminal Ø 80 insu-
lated (7)
N°2 - Internal wall sealing plates
(8)
N°1 - External wall sealing plate
(9)
N°1 - Discharge pipe Ø 80 insu-
lated (10)
N°1 - Concentric bend 90° Ø
80/125 (11)
