* e air intake pipe can be increased to 2.5 metres if the exhaust bend is
eliminated, 2 metres if the air intake bend is eliminated, and 4.5 metres
eliminating both bends.

• Extension pipes and elbows push-ttings. To
install push-tting extensions with other ele-
ments of the ue extraction elements assembly,
proceed as follows: engage the pipe or elbow
with the male side (smooth) in the female
section (with lip seal) up to the stop on the
previously installed element. is will ensure
sealing eciency of the coupling.
• Installation clearances. Figure 1-22 gives the
min. installation space dimensions of the
Ø80/80 separator terminal kit in limited
conditions.
• Figure 1-23 shows the conguration with ver-
tical exhaust and horizontal intake.
• Extensions for the separator kit Ø80/80. e
max. vertical straight length (without bends)
that can be used for Ø80 intake and exhaust
pipes is 41 metres of which 40 intake and 1
exhaust. The total length corresponds to a
resistance factor of 100. e total usable length
obtained by adding the length of the intake and
exhaust pipes Ø80, must not exceed the values
stated in the following table. If mixed accesso-
ries or components are used (e.g. changing from
a separator Ø80/80 to a concentric pipe), the
maximum extension can be calculated by using
a resistance factor for each component or the
equivalent length. e sum of these resistance
factors must not exceed 100.
• Temperature loss in flue ducts. To prevent
problems of ue gas condensate in the exhaust
pipe Ø80, due to ue gas cooling through the
wall, the length of the pipe must be limited to
just 5 m. (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 section
clamp with pin must be installed every 3metres.
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°2 - 90° bend Ø 80 (5)
N°1 - Intake terminal Ø 80 (6)
N°2 - Internal wall sealing plates (7)
N°1 - External wall sealing plate (8)
N°1 - Exhaust pipe Ø 80 (9)
Important: if installation requires extending the ue ttings up to the exhaust a length that exceeds the 12 m recommended, it is necessary to properly
consider the possibility that condensation may form inside the duct and therefore Immergas “Serie Blu” insulated ue ttings, or other ue ttings with
similar characteristics, should be used.
