and one of these (90 degree rectangular duct to duct piece):

connected with about 2m of rectangular 100mm duct. It doesn't seem to be in
black so I'd paint it, and fix with channel clips.

Whilst much depends upon the actual fan your neighbour has used,
their ability to cope with additional ducting varies
considerably.

The end result may range from being imperceptible, to being
equivalent to the handful of used socks I guess you would like to
shove into it.

Additionally, he may well _claim_ reduced performance, simply to
be difficult.

Yes - but I'm not too worried about that side of things. Not yet anyway. I
can't see any duct guidance for any of the Manrose fans. I'd assume it would
put a little extra stress on the fan and reduce efficiency, but hey.


Does the prevailing wind aid or oppose your redirection?


That's part of the problem - it vents into a sheltered area, with walls on 3
sides. So unless there's a fair breeze if just sort of hangs about in a
hollow. The prevailing wind would potentially push the newly sited duct waste
over another neighbour's garden - but it'd take some untypical weather for
that to happen in a noticeable way.

I do propose to give them a note outlining the plan. All they would see is the
rectangular elbow outlet. And all they would smell is their own cooking. Can't
really see why they'd object. The eyesore is on my side.
