5.0 Site Requirements

5.11 Condensate Disposal - Pipe Runs

1. 3.5 metres of flexible 10mm condensate discharge

pipe and a 10mm push fit elbow are supplied with the

boiler.

2. The 10mm pipe can be routed to a maximum of

2.5 metres vertically as measured from the outlet

(equivalent to the total available head of 3 metres)

and then discharge via gravity or be routed

horizontally (Fig. 12).

3. The pipe must be adequately supported, either

using suitably spaced clips or run within larger

diameter pipe. When using clips take care not to

deform or restrict the pipe.

4. When routing the pipe through a wall it must be

suitably sleeved. Also the pipe must not be exposed

to sources of heat, and should be protected in

locations where it may be damaged.

5. The pipe should be routed so that any sharp

bends, dips and loops are avoided. A minimum radius

of 100mm is recommended for any bends (Fig. 13).

No slope is necessary and air breaks are not required

on the pumped part of the run.

6. From ‘A’ to ‘B’ (vertical run) must be NOT

GREATER than 2.5 metres (Fig. 14). The length of

vertical run influences the maximum horizontal run

and number of elbows allowed. From ‘B’ to ‘C’

(horizontal run) can be as shown in the table overleaf.

The permissible number of 90° elbows is also given.

NOTE: The pipe from ‘A’ to ‘C’ must be NOT

GREATER than 10mm diameter !
