CONDENSATE DRAIN CONNECTION
5.15.1
The condensate drain connection is between
Gas service cock and Central Heating Flow
valve connections (Fig.49A). An 25mm
plastic overflow pipe is fitted on the
condensing trap and must should be used
to fit on the drain connection, if required,
to discharge condensate to a drain. The
drain pipe should have a fall of a least 2.5°
away from the boiler. Condensate should, if
possible be discharged into the household
internal drainage system.
If this is not practicable, discharge can be
allowed into the external household drains
or a purpose designed soak away.
It is recommended that any external
condensate drain pipe is insulated and also
preferably of 32 mm diameter, to prevent
freelzing in adverse weather conditions.
The condensate is discharged periodically
in “ slugs” by siphonic action. It is not
necessary to provide air breaks or extra
traps in discharge pipe as there is already a
125mm high trap inside the boiler.
Fitting an extra trap may cause the boiler
siphon to work incorrectly.
Refer to BS5546 or BS6798 for advice on
disposal of boiler condensate.
