min. installation space dimensions of the Ø 80/80
separator terminal kit in limited conditions.
• Figure 1-24 shows the configuration with verti-
cal exhaust and horizontal intake.
• Extensions for separator kit Ø 80/80. The max.
vertical straight length (without bends) usable
for Ø 80 intake and exhaust pipes is 41 metres
of which 40 intake and 1 exhaust. This total
length corresponds to a resistance factor of
100. The total usable length obtained by sum-
ming the Ø 80 intake and exhaust pipe lengths
can reach, as a maximum, the values provided
in the following table. If
mixed accessories or
components are used
, the maximum extension
can be calculated by using a resistance factor
for each component or its
equivalent length.
The sum of these resistance factors must not
exceed 100.
• Temperature loss in flue ducts. To prevent prob-
lems of flue gas condensate in the exhaust pipe
Ø 80, due to fume cooling through the wall,
the length of the exhaust pipe must be limited
to just 5 metres (Fig. 1-25).
If longer distances
must 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 dividing
strip with gusset must be installed every 3 metres.

Kit assembly
(Fig. 1-26): install the flange (4) on the central
hole of the boiler, interposing the 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 (ac-
cording to needs) and replace it with the flange
(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 flange (3). Fit bend (11) with the
male side (smooth) into the female side of flange
(4). Fit the male end (smooth) of the intake ter-
minal (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 cor-
The kit includes:
N°1 - Exhaust gasket (1)
N°1 - Female intake flange (3)
N°1 - Flange gasket (2)
N°1 - Female exhaust flange (4)
N°2 - 90° bend Ø 80 (5)
N°1 - Intake terminal Ø 80 (6)
N°2 - Internal rings (7)
N°1 - External grey wall sealing plate (8)
N°1 - Exhaust pipe Ø 80 (9)

Attention:
if the installation requires an exten-
sion of the flue to the discharge that exceeds the
recommended 12 m, due consideration must be
given to the formation of condensate that may
occur inside the pipe and Immergas insulated
“Blue Series” flue kits or other flues with equiva-
lent characteristics must be used.
