3.23.10 - Removing
the condensation
produced by flue
gas discharge
Due to the high efficiency of this
heater, condensation will form in
the discharge piping as a result of
the cooling of the flue gases. It is
therefore necessary to take every
precaution to prevent this
condensation from going inside the
heater, by collecting it and
removing it from the room.
The condensation must be emptied
in such a way as to avoid the
release of flue gases into drains or
the environment. For this purpose,
use appropriate traps such as the
one illustrated in the figures 14, 15,
16, and 23 or similar.
In particular, the system for
emptying condensation must:
- be connected to the domestic
sewage system through an air trap
to prevent the pressurisation of the
system or the return of foul odours
from the sewers;
- be executed using a tube having
an internal diameter of at least 1/2”
(13 mm);
- be installed so as to prevent the
liquid from freezing; therefore take
care with any outdoor sections;
discharging into gutters or
downpipes is forbidden;
- have a continuous downward
incline toward the point of
discharge; avoid high points which
may put the piping under pressure.
Another technique used to remove
the condensation is to simply
incline the pipe toward the outside
of the building, so that the
condensation discharges outside
(see fig. 14, 22, 25).
