Hi everybody! Such a nice forum, been reading through it quite a lot.

Our kitchen has a particular problem making it seemingly incompatible with many conventional cooker hoods – a lower, sloped part of ceiling (see the photo below). Because of that we have been considering recirculation, eg looking at wall-installed sloped/angled hoods such as this one from Electrolux.

However, all of them come with a metal cover for a duct included ("chimney" part). And in our case that metal cover would make the hood hanging too low over the hob. My question is – is it possible to just skip installing the vertical chimney (since air is recirculated anyway)?

I've found this apparently as one option in the manual (marked as F1). The red circle marks the top chimney part that I'm talking about.

But not sure whether it means what i think it means and also whether it applies just to Electrolux or also to angled hoods of other brands.

Thanks in advance!
