The P20 hood can have either a ceiling or a wall fumes outlet. For the P20 hood with a ceiling fumes outlet, the hole centerline must be at a distance of 10cm from the wall and centred above the hob.

The electric cable outlet must be near the fumes outlet, at a distance of 3.75cm from its centerline, in an area to the side of 5x5cm (inside the steel flue casing; see drawing).
