▶ Ensure that the pipeline is visible.
▶ 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.
5.4 Connecting the condensate drain pipework
▶ Follow the instructions listed here and observe directives
and local regulations on condensed water discharge.
▶ Use PVC or another material that is suitable for draining
the non-neutralised condensed water.
▶ If you cannot guarantee that the materials from which
the drain lines are made are suitable, install a system for
neutralising the condensate.
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 a condensate discharge pipe (21.5 mm, not
included in the scope of delivery) 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 specification "BS 6798"
for installing and maintaining gas-fired boilers with a nominal
heat loading under 70 kW.
5.5 Electrical installation
Danger!
Risk of death from electric shock!
The power supply terminals L and N remain
live even if the product is switched off:
▶ Switch off the power supply.
▶ Secure the power supply against being
switched on again.
