5.5 Boiler Preparation
Lift the boiler into position above the boiler mounting bracket,
lowering the boiler into position at the same time locating the
key hole slots of the boiler on to the securing screws, when
located secure the screws, see diagram 5.5.
6.2 Condensate Connection
The condensate drain connection is at the bottom right of the
boiler.
The drain ends in a spigot which is suitable for push-fit 22mm
(
3 /
4
in.) plastic overflow pipe, for example, Hepworth Polypipe,
Uponor, Osma, Oracstar. If using Marley, Terrain or Hunter
tubing, which is slightly larger, use the silicone sealent provided
in the fittings pack to make a leak proof joint to the drain
connection on the boiler.
The condensate discharge pipe should have a fall of 2 1 /
2
o .
The boiler is fitted with a safety device to prevent the boiler from
working if the condensate pipe gets blocked by either ice or
debris.
It is, therefore, recommended that any external condensate
drain pipe is insulated to prevent it freezing up.
Alternatively, a larger diameter pipe can be used and insulated.
The condensate pipe should be checked during any servicing
and any debris found removed.
It is not necessary to provide air breaks, or traps in the discharge
pipe since the boiler has an integral 50mm trap and siphon.
Refer to the British Gas publication “Guidance Notes for the
Installation of Domestic Condensing Boilers” for advice on the
disposal of the boiler condensate.
