suitable condensate pump in basement and cellar or similar applications.
The boiler condensate trap incorporates a seal of 75mm, therefore it is unnecessary to install an air break and
trap in the discharge pipework.
1. The condensate outlet will accept 21.5mm (
3
/
4
in) plastic overflow pipe. It is strongly recommended that this discharges internally into the
household drainage system . Where this is not possible, discharge into an outside drain is permissible providing every possible precaution is taken to
prevent freezing.
2. Ensure the discharge of condensate complies with any national or local regulations in force. BS 6798 & Part H1 of the Building Regulations give
further detailed guidance .
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 pipework is
NOT suitable for use in condensate discharge systems.
5. The pipe should be a minimum of 21.5mm diameter and must be supported using suitably spaced clips of the correct design to prevent sagging.
6.
It is advisable that the full length of condensate pipe is run internally and preferably be less than 3 metres.
7. Internal runs greater than 3 metres or runs in cold areas should use 32mm waste pipe.
8. External runs MUST be a MINIMUM of 32mm and fully insulated with material suitable for external use.
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.
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) downstream of the trap
iii) to a drain or gully
iv) to a purpose made soakaway
v) pumped into an internal discharge branch (e.g. sink waste) downstream of the trap
vi) pumped into an external soil & vent pipe
vii) to a drain or gully with extended external run & trace heating
It is strongly recommended to discharge internally into the household drainage system. If connecting to a rain water drain, that drain MUST
discharge into a foul drain.
