Zaba, about the grid: mine should have been under the stove as well. I didn’t want that, because I stand right in front of it when cooking and I really find the draft unpleasant. Unfortunately, the installers messed up with the angled parts, supposedly with the one they had, you could only swivel to the right and not to the left. And I am actually a bit annoyed that I gave in to that—because in the current position, it still blows lightly on my feet when I stand at my cutting station. There’s nothing to be done now and I’m sure everyone is different, but I don’t wear slippers and am a bit more sensitive there.
In that respect, I still find the decision NOT to orient the outlet towards the table by far the better choice.
