3.7 Condensate drain
FAILURE
TO
INSTALL
THE
CONDENSATE
DISCHARGE
PIPEWORK
CORRECTLY
WILL
AFFECT THE RELIABLE OPERATION OF THE
DUAL PURPOSE WATER HEATER. The condensate
discharge pipe MUST NOT RISE at any point along
its length. There MUST be a fall of AT LEAST 2.5° (1”
per 20”) along the entire run.
I. The condensat
e outlet terminates in 7/8” nut and
seal for the connection of 7/8” plastic overflow pipe
which should generally discharge internally into the
household drainage system. If this is not possible,
discharge into an outside drain is acceptable.
2. Ensure condensate piping, neutralizer, and
discharge of condensate complies with any and all
local and national codes.
3. The discharge pipe should be run in a proprietary
drain pipe material e.g. PVC, PVC-U, ABS, PVC-C or
PP.
4. Metal pipe work is NOT suitable for use in
condensate discharge systems.
5. The pipe should be a minimum of 7/8” diameter and
must be supported using suitably spaced clips to
prevent sagging.
6. Any pipe fitted externally must not exceed 10 feet.
7 Any condensate discharge pipe work external to the
building (or in an unheated part of it e.g. garage) must
be insulated to protect against frost. It is also
recommended that the pipe diameter is increased to 1
¼”.
8. If the water heater is fitted in an unheated location
the entire condensate discharge pipe should be
treated as an external run.
9. In alI 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.
10. 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 water heater trap and cause
appliance lockout.
Information Only:
Examples are shown of the following methods of
termination:-
i) to an internal soil & vent pipe
ii) via an internal discharge branch (e.g. sink waste)
iii) to a drain or gully
iv) to a purpose made soak away
Ensure condensate piping, neutralizer, and
discharge of condensate complies with any and
all local and national codes.
