5 Before Installation
Boiler
Pipe must terminate above water level
but below surrounding surface. Cut
end at 45°
iv) Termination to a purpose made
soakaway
Further specific requirements for
soakaway design are referred to in
Boiler
BS 6798.
v) pumped into an internal discharge branch
(e.g. sink waste) downstream of the trap
Sink

vi) pumped into an external soil & vent pipe

iii) Termination to a drain
or gully
500mm min
Holes in the soak-away must
face away from the building
Basement or
similar
Pipe must terminate

9. If the boiler is fitted in an unheated location the entire
condensate discharge pipe should be treated as an external run
and sized and insulated accordingly.
10. In all cases discharge pipe must be installed to aid disposal
of the condensate. To reduce the risk of condensate being
trapped, as few bends and fittings as possible should be used
and any burrs on cut pipe removed.
11. When discharging condensate into a soil stack or waste
pipe the effects of existing plumbing must be considered. If soil
pipes or waste pipes are subjected to internal pressure
fluctuations when WC's are flushed or sinks emptied then back-
pressure may force water out of the boiler trap and cause
appliance lockout.
12. A boiler discharge pump is available which will dispose of
both condensate & high temperature water from the relief valve.
It has a maximum head of 5 metres. Follow the instructions
supplied with the pump.
13. Condensate Drain Pipe 'Trace Heating' Elements are
available in various lengths, 1, 2, 3 & 5 metres. Where the drain
is between 3 & 5 metres a 5 metre kit can be used and
"doubled back" upon itself.
14. It is possible to fit the element externally on the condensate
drain or internally as detailed in the instructions provided.
15. The fitting of a 'Trace Heating' Element is NOT a substitute
for correct installation of the condensate drain. ALL
requirements in this section must still be adhered to.
vii) to a drain or gully with extended
external run & trace heating
The 'Trace Heating' element must be installed in
accordance with the instructions supplied.
Boiler
External runs & those in unheated locations still
require insulation.
Pipe must terminate
above water level but
below surrounding
surface. Cut end at 45°
