Condensate Drain; Condensate Pipe Termination Configurations - IDEAL istor HE260 Installation And Servicing

19 CONDENSATE DRAIN

The condensate drain connection point position is shown in
the diagram below. A 700mm long flexible hose is supplied
strapped to the cylinder module frame and an adaptor is
provided in the hardware pack for connection to this. It may be
necessary to make provision for connection to this, prior to
moving the appliance into position.
Note.
A condensate pump kit is available for fitting outside of the
appliance, if the minimum fall of 1 in 20 away from the boiler,
throughout its length is not available.
If fitting this kit refer to the installation instructions within the
kit, otherwise follow the guidance below.
The condensate drain provided on the boiler must be
connected to a drainage point, preferably within the building.
Ensure that the condensate trap is full of water before
commissioning the boiler - refer to Frame 32.
The routing of the drain must be made to allow a minimum
fall of 1 in 20 away from the boiler, throughout its length.
The drainage pipework must be arranged so that obstruction
(e.g. through freezing) of external drainage pipe does not give
rise to spillage within the dwelling.
IMPORTANT.
Any external runs must be insulated.
Excessive external pipe runs should be avoided in order to
prevent possible freezing.
All pipework and fittings in the condensate drain system must
be made of plastic. No other materials may be used.
The drain outlet on the boiler is standard 21.5mm overflow
pipe. This size must not be reduced in any part of its length.

INSTALLATION
If external condensate pipe run is greater than 3m then pipe
must be 32mm nominal diamater. Consideration should be
given to insulating external condensate pipe runs.
In order to defer the onset of freezing of the condensate drain
when the pipe is run externally the pipe should be run as far
as possible within the building.
The boiler condensate drain connection is suitable for Marley
'Terrain' tubing.
A siphon kit is available to prevent freezing.
