Adaptor C9 Kit Installation - Immergas VICTRIX EXA 24 X 1 ErP Instruction And Recommendation Booklet

1.15 ADAPTOR C9 KIT INSTALLATION.

is kit allows an Immergas boiler to be installed
in "C " con guration, with combustion air intake
93
directly from the sha where the ue gas exhaust
is, obtained by means of a ducting system.
System composition.
e system must be combined with the following
components (sold separately) to be functional
and complete:
- kit C Ø 100 or Ø125 version
93
- ducting kit Ø 60 or Ø 80
- fumes exhaust kit Ø 60/100 or Ø 80/125 con-
gured 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. 1-24).
- (Version Ø 125 only) mount the anged adap-
tor (11) interposing the concentric gasket (10)
on the boiler, tting 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 ue system, making sure that
the internal pipe of the concentric kit is tted
properly in the bend of the ducting system
(quota "X" g. 1-25), while the external pipe
must be tted 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 ue
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 car-
ried out by the manufacturer) is not su cient,
remove the residual lubricant using a dry cloth,
then to ease tting 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
sha (Fig. 1-25).
Technical data.
- e dimensions of the sha s must ensure a
minimum gap between the outer wall of the
smoke duct and the inner wall of the sha : 30
mm for circular section sha s and 20 mm in
the event of a square section sha (Fig. 1-23).
- Maximum 2 changes of direction are allowed
on the vertical section of the ue system with
a maximum clearance angle of 30° with respect
to the vertical.
- e maximum vertical extension using a Ø 60
ducting system is 13 m, the maximum exten-
sion 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 C ue system in con gu-
93
rations other than that described (Fig. 1-25)
one must consider that 1 metre of ducted pipe
according to the indications described has a
resistance factor equal to 4.9.
- e 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 C ue system in con gura-
93
tions other than that described (Fig. 1-25) 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.
