For every m

of natural gas that is
burned, between 0.7 and 1.0 litres of
water can accumulate, due to a very
high energy efficiency. Condensate,
which accumulates in the boiler, in
the flue 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 build in 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 flue gas pipe (3).
Once each year the flue gas
connections have to be checked for
leakproofness and the siphon filled
with water.
All floor standing gas fired condensing
boilers contain a siphonic condensate
trap to collect and release condensate.
The amount of condensate formed is
determined by the type of boilers and
the water temperature produced by the
boiler.
Condensate pipework.
Press the supplied plastic ribbon
tube onto the condensate drain at the
bottom of the boiler. Connect the tube
to the main condensate drain (minimum
diameter= 40mm) by means of an open
connection to avoid sewage gasses
coming into the boiler.
Fit a pipe for the condensate drain
behind the hydraulic system. For that
purpose, the lower brackets have
holes allowing the installation of a PVC
drain of ø40mm max. Use this drain
to connect the individual condensate
drains of each boiler.
The siphon of a flue gas system can
also be connected, if required, by
means of an open 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.
