10.1 - “Coaxial 60/
100PP”
polypropylene
system
The boiler is not supplied with the
fittings needed for connecting a coaxial
vent/combustion air system. A special
kit must be ordered to connect the
boiler with the “Coaxial 60/100PP”
polypropylene vent. Figure 30 shows
how to install the “Coaxial 60/100PP”
fitting above the boiler:
WARNING!!! Carefully follow
installation steps below, for the
coaxial pipe assembly (elbows and
extensions), as illustrated in figure
31. it is necessary to properly insert
the internal and external pipe and
mechanically secure them by using
a stainless steel self tapping screw.
Improper venting can result in
excessive levels of carbon
monoxide or a fire, which can
result in severe personal injury or
death!
In particular:
 slip-fit the extension “1” and “2” (see
figure 31) together;
 drill a suitable hole “3” with a drill “4”
(see figure 31) in a position where
the two pipes “1” and “2” are
overlapped;
 insert a suitable stainless steel self
tapping screw “5” and tight it with a
screwdriver “6”
It is recommended that wall sleeve
be used when installing the coaxial
60/100PP system through an
exterior wall. This will allow the
system to be easily slipped out for
access during routine maintenance.
Horizontal coaxial systems must
always be pitched by at least 1/4 in/
ft, (21 mm/m) towards the boiler.
The “Coaxial 60/100PP” system
should extend out of the wall to the
dimensions shown in figure 33.
