5.6 - Condensate
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,
fi gure 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 10. The
condensation disposal system must:
A = 3/4" pipe extension (not provided)
B = Discharge device open to the atmosphere (not
provided)
C = Condensate discharge pipe
Figure 10 - Relief valve connection
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 fi gure 11);
comply with national and/or local
codes for condensate neutralizer
between pipe "C" of fi gure 10 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;
be 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.
5.7 - 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 fi gure
10.
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!
