disposal
WARNING! The condensate trap
must be connected to the boiler per
the following instructions or
combustion gases will enter the
room. This can result in excessive
levels of carbon monoxide which
can cause severe personal injury or
death!
This boiler produces water as a
byproduct of combustion. The boiler is
equipped with a condensate trap, figure
1, item 46, for the evacuation of
condensate and to prevent the leakage
of combustion products. The
condensate trap drains through pipe
“C” shown in Figure 13. The
condensation disposal system must:
be connected to the domestic
waste disposal system by means of
an appropriate trap capable of
preventing the pressurization of the
condensate system and the return
of sewer gases (see figure 14);
comply with national and/or local
codes for condensate neutralizer
between pipe “C” of figure 13 and the
waste disposal system;
be carried out with a pipe with an
internal diameter equal to or greater
than
1/2 in
,
13 mm
;
be installed in such a way so as to
avoid the freezing of the liquid;
never discharge into gutters or rain
collectors;
properly pitched towards the point
of discharge avoiding high points,
which could place the condensate
system under pressure;
CAUTION!!! The condensate
drainage system is designed to
empty all the condensate produced
by one boiler only. Each boiler
must be equipped with its own
condensate drainage system or the
drainage system may malfunction.
5.8 - Relief valve
Each boiler is equipped with a safety
relief valve set at
30 psi
(2 bar)
which
must be piped in accordance with the
ANSI/ASME Boiler and Pressure
Vessel Code, Section IV, to prevent
scalding in the event of a discharge,
see Figures 1, item “38” and figure 13.
WARNING!!! Failure to properly
pipe the relief valve discharge can
result in scalding of individuals and
animals. Never install any type of
valve between the boiler and the
relief valve or an explosion
causing extensive property
damage, severe personal injury or
death may occur!
