Extensions for separator kit Ø 80/80
The maximum vertical straight length (without bends) that can be
used for Ø 80 intake and exhaust pipes is 40 metres, regardless
from whether they are used for intake or exhaust.
The maximum horizontal straight length (with bend in suction
and in exhaust) that can be used for Ø 80 intake and exhaust pipes
is 27 metres or 35m intake.
Please note the type of installation C42 must be done with a natu-
ral draught flue.
To favour the removal of possible condensate forming in
the exhaust pipe, tilt the pipes towards the boiler with a
minimum slope of 1.5% (Fig. 28)
1.18 C9 ADAPTOR KIT INSTALLATION
This kit allows an Immergas boiler to be installed in “C92” confi-
guration, with combustion air intake directly from the shaft whe-
re the flue gas exhaust is, obtained by means of a ducting system.
System composition
The system must be combined with the following components
(sold separately) to be functional and complete:
- kit C92” Ø 100 or Ø 125 version;
- ducting kit Ø8 0 rigid and Ø 80 flexible;
- flue exhaust kit Ø 60/100 or Ø 80/125 configured according to
the installation and type of boiler.
Mounting the C9 adapter kit (Fig. 30)
(Version Ø 125 only) before assembly check the gaskets
are in the right position.
In the event component lubrication (already carried out
by the manufacturer) is not sufficient, remove the resi-
dual lubricant using a dry cloth, then to ease fitting coat
the parts with common or industrial talc.
To favour the removal of possible condensate forming in
the exhaust pipe, tilt the pipes towards the boiler with a
minimum slope of 1.5% (Fig. 28)
1. Mount the components of kit "C9" on the door (A) of the
ducting system (Fig. 30).
2. (Version Ø 125 only) mount the flanged adaptor (11) interpo-
sing the concentric gasket (10) on the boiler, fitting it with the
screws (12).
3. Mount the ducting system as described in the relative in-
structions sheet.
4. Calculate the distances between the boiler drain and the bend
of the ducting system.
5. Prepare the boiler flue system, making sure that the internal
pipe of the concentric kit is fitted up to the end stop in the
ducting system curve (Quota "X" Fig. 31), whereas the external
pipe must reach the end stop of the adapter (1).
6. Mount the cover (A) complete with adaptor (1) and caps (6) on
the wall.
7. Assemble the flue system to the ducting system.
Once all components have been assembled properly, the exhaust
flue gas will be expelled via the ducting system; the combustion air
for normal boiler operation will be aspirated directly by the shaft
(Fig. 31).
