Installing the condensate trap

DANGER: Danger of fatal accident due to poisoning.
▶ If the condensate trap is not filled with water, flue gas
can escape and put people's lives at risk.
▶ Fill the condensate trap (supplied with the boiler) with water
( fig. 16).
Fig. 16 Filling the condensate trap with water
▶ Connect the condensate trap [1] to the condensate drain outlet
(CDO).
The trap is fitted with a bayonet connection. After
pushing [step 1] the trap upwards into place, you have
to turn it a ¼ turn anticlockwise [step 2] until it locks into
position.

8.2.10 Condensate removal

Positioning and termination of the condensate drain pipe
The condensate pipe should run and connected to the internal sewage
pipe in the house 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 sewage pump.
WARNING:
Any external run must be insulated with water proof
insulation.
It should be noted that the connection of a condensate pipe to a drain
may be subject to local building controls.
