How would you classify this?

Flue 250 to edge of extract and not loving the corner and window. Boiler is a battered old 28CDi. I'd love to get it gone but not able to prove fumes in building.
Bearing in mind others have been and not even mentioned, I need to be careful but what's the worst I can actually do?
Against my personal judgement but can't see how it's not just NCS?

Would have thought ncs, extractor could have been fitted after boiler. Does the extractor fan work?

Yea and its got a fair run of solid duct. I agree NCS. I just see these with the old dilapidated boiler and want to do something about it but with a tenanted property like this it's going to have to fall over first
