DEALING WITH CONDENSATE
Always read the Appliance manufacturers installation instructions in
conjunction with those from Cox Geelen.
If the appliance manufacturers installation instructions state that
condensate cannot be discharged through the boiler appliance
then the fl ue gas condensate must not be allowed to fl ow back to
the boiler. This can be achieved by fi tting the condensate trap and
drain component into the CoxDENS
®
PPs fl ue system.
Regardless of boiler appliance fl ue system installation mode -
Vertically or Horizontally - the condensate trap and drain can be
fi tted - see diagrams below. The condensate trap’s drain off pipe
must be connected to a condensate resistant tube of minimum
internal diameter ¾”, then via a siphon/ airlock controlled outfl ow
to a secured “open” connection to the sewer drain or neutralising
system. An appropriately sized siphon/airlock MUST be fi tted to
maintain room sealed conditions, preventing fl ue gas emissions
into the boiler room and equally to prevent back fl ow of fumes from
the sewer discharge point.
To avoid condensate freezing and disruption of normal operation
of the appliance the condensate evacuation pipe routing should be
suitably arranged internally wherever possible.
Exposure of condensate collection and discharge pipe work to
extreme temperatures and UV light should be avoided at all times.
Condensate removal and disposal must conform to NEN 3287 and
NEN 3215. All components within this condensate collection and
discharge system should be manufactured in condensate resistant
materials- this can be assured by use of the Cox Geelen siphon and
drain pipe (part no 0004.CA.000).
The condensate removal components, siphon and discharge pipe
work must be inspected and maintained annually by suitably
qualifi ed appliance service engineers ideally at the annual service
of the appliance.
