NB: When installing Ø 80 pipes, a section clamp with pin must be installed
every 3 metres.
Insulated separator kit Ø 80/80. Kit assembly: install flange (4) on the
middle hole of the boiler, interposing the seal (1) and secure with the screws
included in the kit. Remove the flat flange on the side hole (according to
requirements) and replace it with flange (3) interposing seal (2) already fitted
on the boiler and secure with the screws supplied. Insert and slide cap (6)
on bend (5) from the male end (smooth), then fit the male end (smooth) of
the bends (5) in the female end of flange (3). Fit the male end (smooth) of
bend (11) in the female end 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 to have already inserted the rings (8-9) that ensure correct installation
between pipe and wall, then fix the closing cap (6) on the terminal (7). Fit
the male end (smooth) of the exhaust pipe (10) up to the stop on the female
end of the bend (11), making sure to have already inserted the ring (8) that
ensures correct installation between pipe and wall.

1 - Outside ring (9)
1 - Insulated exhaust pipe Ø 80 (10)
1 - Concentric 90° bend Ø 80/125 (11)
• Temperature loss in insulated fume ducting. To avoid problems of fume
condensate in the insulated exhaust pipe Ø 80, due to cooling through
the wall, the exhaust pipe length must be limited to 12 metres. The figure
above illustrates a typical insulation application in which the intake pipe
is short and the exhaust pipe very long (over 5 m). The entire intake pipe
is insulated to prevent moist air in the place where the boiler is installed,
condensing in contact with the pipe cooled by air entering from the

• Coupling of extension pipes and elbows. To install snap-fit extensions
with other elements of the fume exhaust system, proceed as follows: fit
the male end (smooth) of the concentric pipe or concentric elbow up
to the stop on the female end (with lip seals) of the previously installed
element; this will ensure correct hold and joining of the elements.
• Insulation of separator terminal kit. In case of problems of fume con-
densate in the exhaust pipes or on the outside of intake pipes, Immergas
supplies insulated intake and exhaust pipes by request. Insulation may be
necessary on the exhaust pipe due to excessive temperature loss of fumes
during conveyance. 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 ambient air. The figures below 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. Starting with both Ø 80 elbows
insulated is technically not possible, as clearances will not allow it. How-
ever starting with an insulated elbow is possible by choosing either the
intake or exhaust pipe. When starting with an insulated intake bend, it
must be inserted on its flange up to the stop on the fume exhaust flange,
which will ensure that the two intake and exhaust outlets are at the same
height.

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.
NB: When installing the insulated pipes, a section clamp with pin must
be installed every 2 metres.
