5.14.10 - “80/125PP vertical coaxial”
System (polypropylene) (C13; C33)
AGUADENS 37
The appliance is supplied as per standard without fittings
for the connection of the fumes exhaust/air intake. To
connect it to a vertical 80/125 system, the relevant kit must
be requested and must be installed as in figure 5-31.
ATTENTION !!! Scrupulously follow the installation
phases of the coaxial pipe as illustrated in figure 5-33. In
particular:
1.- introduce the coaxial pipe “C” inside the bend “A”;
2.- fix the external pipe using the stainless steel self-threading
screws “B”.
ATTENTION !!! The coaxial exhaust and
intake pipes must be appropriately sustained via rigid
brackets positioned no more than 1 metre from each
other. The brackets must be fixed to rigid walls that can
support the weight of the pipe itself.
ATTENTION !!! Once these operations have
been performed, check that the exhaust/intake terminal
is exposed to the outdoors with the tolerances given in
figure 5-34.

Take particular care with the installation of pipes in the
part that passes through the wall to the outside. Normal
maintenance operations must always be possible, therefore
install the pipes in a sheath so that they can slide out.

The horizontal exhaust flue pipes must always have an
inclination of 2% with the fall back towards the appliances
as opposed to the wall terminal.

The combined exhaust/air intake pipe can be extended up
to a maximum distance as indicated in the table in section
9 at the end of the manual. Every 90° bend has a loss
equivalent to value on section 9. Every 45° bend has a loss
equivalent to value on section 9.
