z
Connect pipes free of strain (fig. 4).
1.6.5
Condensate removal
Positioning and termination of the condensate drain pipe
The condensate pipe should be run and terminate internally to
the house soil and vent stack or waste pipe. Alternatively, the
condensate can be discharged into the rainwater system if
connected to a foul water draining system, or into a purpose-
made soak away (condensate absorption point).
All connecting drainage pipework should generally have a fall
of at least 2.5° to the horizontal, or approximately 50 mm per
metre of pipe run. If this is can not be achieved, consider the
use of a condens pump.
If an external pipe run is unavoidable then the run should be
insulated with water proof insulation limited to 3 m in length.
Should this be exceeded then the pipework diameter should be
increased to 32mm and the pipework insulated using weather
proof materials.
It should be noted that the connection of a condensate pipe to
a drain may be subject to local building controls.

Compression fitting
CAUTION!
DO NOT use galvanised pipes or fittings.
The hot water heat exchanger is made of
copper and is liable to suffer the effects of elec-
trolytic corrosion.
NOTE
When using plastic pipes, observe the
supplier’s instructions - especially those refer-
ring to recommended jointing techniques and
the notes relating to the heating system water
on page 5.
WARNING!
Any external run must be insulated with water
proof insulation.
