Buderus 500-24C Installation And Maintenance Instructions Manual page 17

External termination via internal branche (e.g. sink
waste)
The condensate drainage pipe should have a minimum
outside diameter of 21.5 mm with no length restriction.
The connection should preferably be made downstream
of the sink waste trap. If the connection is only possible
upstream, then the air break is needed between the two
traps. This can be provided by the sink waste pipe
( fig. 14 and fig. 15).
