Should the condense pipe have a fall angle

[shambolic]

It's always been required to run in 32mm outside. I've been to jobs where a 32mm condensate has frozen, god knows what it's like with 19mm running outside in winter!

Try our climate(Scotland) we had lagged 32mm condense pipes going into 5" cast downpipes and the bloody downpipes froze it was that bad.
Last year was mental. Recommend all condense pipes in Scotland should be run internally.

That's because 9/10 frozen condense lines I saw last winter were all on worcesters due to the trickle design of their condense.

That is right on the money, what is the matter with Worcester and their condense traps? They've had about three redesigns and they still dribble and freeze.

If I had to design a boiler that would freeze up every winter, I'd start with a Bosch condensate siphon, genius.

I thought you weren't alowed to run the condense into cast downpipes?

You can as long as there is another source of water coming from above to wash the condensate away.
