Condensate connection
HAZARD:
Danger of death due to
poisoning! If the siphon is not
filled with water, or if any connections
are open, then escaping waste gas can
pose a hazard of death for people.
Condensate connection
For every m3 of natural gas that is
burned, between 0.7 and 1.0 litres of
water can accumulate, due to a very
high energy utilization. Condensate,
which accumulates in the boiler, in
the waste gas pipe or in the chimney,
must be drained to the public sewage
system.
In this regard, country-specific
regulations must be taken into account.
A neutralization of the condensate may
be required. It must be possible for
the condensate to visibly drain into a
funnel-siphon (2) at the installation site.
A fixed connection to the public sewer
system is not permitted.
For condensate drainage, only
corrosion-resistant and certified
materials may be used. The drainage
must be carried out in a frost-free
space. The drainage pipe should have
a slope, so as to avoid a backwash of
the condensate.
Filling of the siphon
Before the boiler is taken into
operation, the equipment siphon (1)
must be filled with water, so as to
prevent an emission of waste gas from
the condensate connection. Filling
is carried out most easily by pouring
approximately 0.5 litres of water into
the waste gas pipe (3); otherwise
screw off the siphon to fill it.
The condensate drain should be
cleaned during maintenance and
inspection works, however at least
once each year, whereby the siphon
and the waste gas connections are
also check for leakproofness and the
equipment siphon is filled with water.
