Installation and maintenance instructions SUSTAIN ..s 0020200967_00
▶
The pipe must have a continuous fall and be routed to a
position so that any discharge of water, possibly boiling,
or steam cannot create any danger to persons, damage
to property or external electrical components and wiring.
◁
The components must be set up in such a way that
you can see the water flowing out.

▶
Follow the instructions listed here and observe any legal
directives and local regulations on condensate discharge.
▶
Use PVC or another material that is suitable for draining
the non-neutralised condensate.
▶
If you cannot guarantee that the materials from which
the drain lines are made are suitable, install a system for
neutralising the condensate.
▶
Ensure that the connection between the condensate
drain pipework and the drain hose is not air-tight.
Note
The condensate drain pipework must have a
continuous fall (45 mm per metre) and should
whenever possible terminate at a suitable
drain point within the heated envelope of the
building that will remain frost free under long
periods of low external temperatures.
▶
Connect the condensate siphon
(1)
. Use the supplied
drain hose
(2)
for this.
▶
Connect condensate drain pipework (21.5 mm, not in-
cluded in the scope of delivery)
(3)
to the drain hose
(2)
.
▶
During installation remove all burs from inside of cut pipe
work and avoid excessive adhesive which may trap small
pockets of water close to the pipe wall which can freeze
and build into a larger ice plug.
▶
As with other pipe work insulate the condensate dis-
charge pipe to minimise any risk of freezing and beware
when crossing cavities that the fall is maintained and the
pipe sleeved.
You can find further information in BS 6789: "Specification
for installing and maintaining gas-fired boilers with a nominal
heat loading less than 70 kW".

For each additional 90° elbow (or two 45° elbows) that is
required, the length
