1.14 SEPARATOR KIT INSTALLATION.
Type C configuration, sealed chamber and
fan assisted.
This kit allows air to come in from outside the
building and the fumes to exit from the chimney
or flue through divided flue exhaust and air
intake pipes. Combustion products are expelled
from pipe (S). Air is taken in through pipe (A)
for combustion. Both ducts can be routed in
any direction.
Separator kit Ø 80/80.
Kit assembly (Fig. 1-20):
install the flange (4) on the central hole of the boiler
inserting the gasket (1) and tighten using the hex
head and flat tip screws contained in the kit, insert
the anti-pulse plate up to the stop (5). Remove the
flat flange present in the lateral hole with respect
to the central one (according 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. Fit the male end
(smooth) to the bends (6) in the female end of the
flanges (3 and 4). Fit the intake terminal (7) with
the male section (smooth) in the female section
of the bend (6) up to the stop, ensuring that the
internal and external wall sealing plates are fitted. Fit
the exhaust pipe (10) with the male end (smooth)
in the female end of the bend (6) up to the stop,
making sure that the internal wall sealing plate has
been fitted, this will ensure sealing and joining of
the kit elements.
• Installation clearances (Fig. 1-21). The mini-
mum installation clearance measurements of
the Ø 80/80 separator terminal kit have been
stated in some limit conditions.
• The figure (Fig. 1-22) shows the configuration
with vertical 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 summing
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 pipes (Fig. 1-23). To
prevent problems 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 m. If longer distances must be
covered, use Ø 80 pipes with insulation (see
insulated separator kit Ø 80/80 chapter).

The kit includes:
N°1 - Exhaust gasket (1)
N°1 - Flange gasket (2)
N°1 - Female intake flange (3)
Attention:
the boiler is designed to evacuate
the combustion products up to a maximum
extension of 27 linear metres from the exhaust,
with 1 m plus 90° bend at the intake. If the instal-
lation requests a development of the flue to the
discharge that exceeds the recommended 12 m,
due consideration must be given to the formation
of condensate that could take place inside the
pipe and Immergas insulated “Blue Series” flue
kits must be used.
