Hi

I'm about to buy a Neff U1721 built under oven and need to prepare the space
in my kitchen.

So far Ive only been able to find info on aperture dimensions.

I'd like to know how its actually held in place and what I need to provide
within the aperture for the fixings.

I'm reasonably handy with DIY and a bit of a tech head, but have never
fitted a built in oven before. So any tips/advice on what to do or watch out
for would be greatly appreciated.

Thanks.

Rob
