1.18 ADAPTOR C9 KIT INSTALLATION.
This kit allows an Immergas boiler to be installed in "C
93
" config-
uration, with combustion air intake directly from the shaft where
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 C
93
Ø 100 or Ø125 version;
- rigid ducting Ø 60 and Ø 80 and flexible Ø 50 and Ø 80 kit;
- flue exhaust kit Ø 60/100 or Ø 80/125 configured 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. 27).
- (Version Ø 125 only) mount the flanged adaptor (11) interposing
the concentric gasket (10) on the boiler, fitting it with the screws
(12).
- Mount the ducting system as described in the relative instruc-
tions 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 up to the end stop in the ducting
system curve (Quota "X" Fig. 28), whereas the external pipe must
reach the end stop of the adapter (1).
N.B.:
to encourage the removal of possible condensate forming
in the exhaust pipe, tilt the pipes towards the boiler with a min-
imum 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 properly, 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. 28).
