Renew outside flue terminal

[Be kind]

If I’ve had a whole new flue fitted to my boiler and going outside through wall. Should the engineer fit a new outside terminal as well. Or is this not needed?

Depends if it’s ok / sound I’m guessing the reason for the new flue is rusting ?

 

[Be kind]

No, the engineer said carbon monoxide

I would say it’s fine as there’s no seals in the last / terminal end just the connecting pieces
