worcester 24i flue

[shaunsparks]

Hi
I am after some advice regarding the flue that as just been installed to a new worcester 24i combi.The old boiler which was a Vokera had a small vent coming out of the the boiler to the outside wall for a flue ,but the new boiler as what i only describe as what resembles a submarine periscope (sorry but thats the best way to describe it ha ) going out of the back of the boiler and running up the outside wall.
Is this a safety feature as it is about 300 mm from a window or can i ask for it to be changed as its quite noticeable.
Thanks for any replies.

Its a diverter/management kit. Its fine, leave it. As long as it is 300mm from an opening. (Other restrictions ommitted) for the ease of simplicity and my valued bath time).
