Adaptor C9 Kit Installation - Immergas VICTRIX TERA 24 PLUS Instruction Booklet And Warning

1.18 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
- rigid ducting Ø 60 and Ø 80 and exible Ø 50
and Ø 80 kit;
- ue exhaust kit Ø 60/100 or Ø 80/125 con g-
ured 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. 29).
- (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
up to the end stop in the ducting system curve
(Quota "X" Fig. 30), whereas the external pipe
must reach the end stop of the adapter (1).

A 1 Ducting kit door
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 carried 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 pro-
perly, 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. 30).
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. 28).
- 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
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 C ue system in con g-
93
urations other than that described (Fig. 30)
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. 30) 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.
