6.7 Connecting the condensate pipe
NOTICE
If the waste water pipe is blocked, this can damage the boiler.
A blockage in the waste water pipe can prevent the removal of
condensate from the boiler if the condensate drain line is permanently
connected to the waste water pipe.
▶ Make sure that the connection between the condensate pipes of the
boiler and the waste water pipe connection is unobstructed.
▶ Use a waste water pipe made of plastic material with a diameter of at
least Ø 40 mm to remove the condensate.
▶ Install a siphon in the waste water pipe.
▶ Install horizontal pipe sections so they slope towards the downpipe.
The maximum length of the horizontal pipe section in this case is 5 m.
▶ Fill siphon in the waste water pipe.
6.8 Connecting heating pipes (without connection set)
NOTICE
If the operating pressure is too high, this can damage the boiler.
▶ Install a diaphragm safety valve between the boiler and the service
shut-off valve.
