DEALING WITH CONDENSATE
Always read the Appliance manufacturers installation instructions
in conjunction with those from Cox Geelen.
If the appliance manufacturer’s installation instructions state that
condensate cannot be discharged through the boiler appliance
then the flue gas condensate must not be allowed to flow back to
the boiler. This can be achieved by fitting the condensate trap and
drain component into the Coxcentric flue system.
Regardless of boiler appliance flue system installation mode -
Vertically or Horizontally - the condensate trap and drain can be
fitted - see diagrams below.
The condensate trap's drain off pipe must be connected to
a condensate resistant tube of minimum internal diameter
3”/4”, then via a siphon/ airlock controlled outflow to a secured
“open” connection to the sewer drain or neutralising system. An
appropriately sized siphon/airlock MUST be fitted to maintain
room sealed conditions, preventing flue gas emissions into the
boiler room and equally to prevent back flow 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.0-00).
The condensate removal components, siphon and discharge
pipe work must be inspected and maintained annually by suitably
qualified appliance service engineers ideally at the annual service
of the appliance.
