conveying exhaust fumes from condensing boilers, nor
vice versa.
● In order to make the choice of which flue to install easier, in
addition to being drawn differently, the above-mentioned system
is also differentiated in the flue catalogue and general price list
by the insertion of the words "...in polypropylene..." .
● It is recommended that:
o
for the exhaust discharge duct, the entire length of the flue
slopes upwards towards the exterior in order to facilitate the
flow of condensate back to the combustion chamber, which
has been specifically designed to collect and drain the acidic
condensate;
o
for the air intake, the entire length of the duct slopes upwards
towards the boiler to prevent the entry of rainwater, dust or
foreign bodies into the pipe;
o
in case of a vertical flue pipe installation, a condensate trap is
fitted at the base of the flue installation and connected into
drainage system (see fig. 1);
● In the case where a horizontal coaxial system is installed, the
coaxial terminal must be positioned horizontally in that the
exhaust duct has been specifically designed with the required
slope and the air intake has been suitably protected against the
weather
