7.0Site Requirements

7.6Condensate 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 terminates in a 1” BSP nut and seal for the connection of 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 6798:2000 & 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.

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:-

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 soakaway
