Adaptor C9 Kit Installation - Immergas VICTRIX 24 TT 1E Instruction And Warning Book

1.16 ADAPTOR C9 KIT INSTALLATION.

This kit allows to install an Immergas boiler in
configuration "C93", achieving the combustion
air intake directly from the shaft featuring the
fumes exhaust, 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 C93 version Ø 100 or Ø125
- ducting kit Ø 60 or Ø 80
- fumes exhaust kit Ø 60/100 or Ø 80/125 con-
figured according to the installation and type
of boiler.
Kit Assembly.
- Mount the components of kit "C9" on the door
(A) of the ducting system (Fig. 1-25).
- (Version Ø 125 only) mount the flanged adap-
tor (11) interposing the concentric gasket (10)
on the boiler, fitting it with the screws (12).
- Mount the ducting system as described in the
relative instructions sheet.
- Calculate the distances between the boiler drain
and the bend of the ducting system.
- Prepare the boiler flue system, making sure that
the internal pipe of the concentric kit is fitted
properly in the bend of the ducting system
(quota "X" fig. 1-26), while the external pipe
must be fitted on the adaptor until it stops (1).
N.B.: to encourage the removal of possible
condensate forming in the exhaust pipe, tilt
the pipes towards the boiler with a minimum
slope of 1.5%.

- Mount the cover (A) complete with adaptor (1)
and caps (6) on the wall and assemble the flue
system to the ducting system.
N.B.: (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 residual lubricant using a dry cloth, then
to ease fitting coat the parts with common or
industrial talc.
Once all components have been assembled prop-
erly, the exhaust fumes will be expelled via the
ducting system; the combustion air for normal
boiler operation will be aspirated directly by the
shaft (Fig. 1-26).
Technical data.
- The dimensions of the shafts must ensure a
minimum gap between the outer wall of the
smoke duct and the inner wall of the shaft: 30
mm for circular section shafts and 20 mm in
the event of a square section shaft (Fig. 1-24).
- Maximum 2 changes of direction are allowed
on the vertical section of the flue system with
a maximum clearance angle of 30° with respect
to the vertical.
- The maximum vertical extension using a Ø
60 ducting system is 13 m, the maximum
extension includes 1 bend Ø 60/10 at 90°, 1 m
of horizontal pipe 60/100, 1 90° ducted bend
Ø 60 and the roof terminal for ducting.

To determine the C93 flue system in configu-
rations other than that described (Fig. 1-26)
one must consider that 1 metre of ducted pipe
according to the indications described has a
resistance factor equal to 4.9.
- The maximum vertical extension using a Ø 80
ducting system is 28 m, the maximum exten-
sion includes 1 adapter 60/100 to 80/125, 1 87°
bend Ø 80/125, 1 m of horizontal pipe 80/125,
1 90° ducted bend Ø 80 and the roof terminal
for ducting.
To determine the C93 flue system in configura-
tions other than that described (Fig. 1-26) one
must consider the following pressure drops:
- 1 m of concentric pipe Ø 80/125 = 1 m of
ducted pipe;
- 1 87° bend = 1.4 m of ducted pipe;
Consequently one must subtract the equivalent
length of the part added to the 28 m available.
