5.3 Condensate Disposal
The Warmflow high efficiency condensing boiler is supplied with a factory fitted,
self sealing condensate trap. The trap has been fitted inside the boiler casing to
the right hand side.
The condensate drainage pipe within the boiler is a flexible plastic hose which can
be trimmed to length. 3/4” or 22mm pipe should be connected to the flexible hose.
The pipe should not be made from steel or copper. The drainage pipe may run
into an internal soil stack or waste pipe, an external gulley, hopper or soakaway
as shown below.
The boiler when fully condensing will produce a maximum of 1.5 litres per hour of
condensate. It is recommended that the drainage pipe should have a minimum fall
of 1:20. This pipe must be protected from freezing either by insulating or using
large diameter pipework in exposed locations.
