5.7 Connecting the condensate drain pipe
▶ Connect the condensate drain pipe to the syphon.
Observe the following regulations:
• The waste water disposal regulations.
• Plastic pipework must be used to drain the condensate, at least until
it is delivered to the sewage system.
• The condensate must be able to run into a funnel (or neutralisation
tank) without restrictions. This prevents condensate from building
up in the boiler. The syphon in the connection kit must no be
permanently connected to the condensate drain pipe. The minimum
distance between the syphon and the condensate drainage pipe is 2
cm [1].
DANGER: Danger of fatal accidentdue to poisoning.
▶ If the syphon is not filled with clean water, flue gas
can escape and put people's lives at risk.
