7.0Site Requirements

7.7Condensate Drain

FAILURE TO INSTALL THE CONDENSATE DISCHARGE PIPEWORK CORRECTLY WILL AFFECT THE RELIABLE OPERATION OF THE BOILER

The condensate discharge pipe MUST NOT RISE at any point along its length. There MUST be a fall of AT LEAST 2.5° (50mm per metre) along the entire run.

1. The condensate outlet will accept 21.5mm (3/4in) 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 the discharge of condensate complies with any

national or local regulations in force.

BS 6798 & Part H1 of the Building Regulations give further

guidance.

3. The discharge pipe should be run in a proprietary drain pipe

material e.g. PVC, PVC-U, ABS, PVC-C or PP.

Pipe must terminate above water level but below surrounding surface

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 to prevent

sagging.

6.

It is advisable to keep the condensate pipe internal.

7.

External runs greater than 3 metres or runs in cold areas

should use 32mm waste pipe.

8. If the boiler is fitted in an unheated location the entire

condensate discharge pipe should be treated as an external

run.

9. 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.

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 boiler trap and

cause appliance lockout.

Examples are shown of the following methods of termination:-
