length corresponds to a resistance factor of
100. The total usable length obtained by the
sum of the Ø 80 intake and exhaust pipe lengths
can reach, as a maximum, the values provided
in the following table. If
mixed accessories or
components are used , the maximum extension
can be calculated by using a resistance factor
for each component or its equivalent length.
The sum of these resistance factors must not
exceed 100.
• Temperature loss in flue ducts. To prevent
problems of flue gas condensate in the exhaust
pipe Ø 80, due to fume cooling through the
wall, the length of the pipe must be limited to
just 5 m. Fig. 1-25). If longer distances must be
covered, use Ø 80 pipes with insulation (see
insulated separator kit Ø 80/80 chapter).
N.B.: when installing the Ø 80 ducts, a dividing
strip with gusset must be installed every 3 metres.
• Insulated separator kit Ø 80/80. Kit assembly
(Fig. 1-26): install the flange (4) on the central
hole of the boiler, interposing the gasket (1)
and tighten with the flat-tipped hex screws
included in the kit. Remove the flat flange
present in the lateral hole with respect to the
central one (according to needs) and replace it
with the flange (3), positioning the gasket (2)
already present in the boiler and tighten using
the supplied self-threading screws. Insert and
slide cap (6) onto bend (5) from the male side
(smooth), and join bends (5) with the male
side (smooth) in the female side of flange (3).
Fit bend (11) with the male side (smooth) into
the female side of flange (4). Fit the male end
(smooth) of the intake terminal (7) up to the
stop on the female end of the bend (5), making
sure you have already inserted the wall sealing
plates (8 and 9) that ensure correct installation
between pipe and wall, then fix the closing cap
(6) on the terminal (7). Join the exhaust pipe
(10) with the male side (smooth) in the female
side of the bend (11) to the end stop, ensuring
that the wall sealing plate (8) is already inserted
for correct installation between the pipe and
flue.
• Insulation of separator terminal kit. Whenever
there are flue gas condensate problems in the
exhaust pipes or on the external surface of the
intake pipes, on request Immergas supplies
insulated intake-exhaust pipes. Insulation
my be necessary on the exhaust pipe, due to
excessive loss of temperature of the flue gas on
their route. Insulation may be necessary on
the intake pipe as the air entering (if very cold)
may cause the outside of the pipe to fall below
the dew point of the environmental air. The
figures (Fig. 1-27 and 1-28) illustrate different
applications of insulated pipes.
Insulated pipes are formed of a Ø 80 internal
concentric pipe and a Ø 125 external pipe with
static air space. It is not technically possible
to start with both Ø 80 elbows insulated, as
clearances will not allow it. However starting
with an insulated elbow is possible by choosing
either the intake or exhaust pipe. When starting
with the insulated intake bend it must be
engaged on its flange until it is taken up to stop
on the flue gas exhaust flange, a situation that
takes the two intake flue gas exhaust outlets to
the same height.
• Temperature loss in insulated flue ducting.
To prevent problems of flue gas condensate in
the exhaust pipe Ø 80, due to flue gas cooling
through the wall, the length of the pipe must be
limited to 12 m. The figure (Fig. 1-28) illustrates
a typical insulation application in which the
intake pipe is short and the exhaust pipe is
very long (over 5 m). The entire intake pipe is
insulated to prevent moist air in the place where
the boiler is installed, in contact with the pipe
cooled by air entering from the outside. The
entire exhaust pipe, except the elbow leaving
the splitter is insulated to reduce heat loss from
the pipe, thus preventing the formation of fume
condensate.
N.B.: when installing the insulated pipes, a
section clamp with pin must be installed every
2 metres.
