3 Fix the duct sections as you please, e.g.,
by bricking them in or by fixing them with
screws. If using screws, mind their posi-

Note:
Seal any gaps between sleeve and wall in a
draught- and leakage-free manner.
4 Drill the (∅ 5mm) grille fixing holes into
the flanges of the sleeve section that is
fixed to the outer wall.

grille flanges. The paste is to seal off the
gap between grille and sleeve in a
draught- and leakage-free manner.

metal screws.

Caution:
Place the grille with the blades correctly
positioned: oriented outward to allow for run-
off.
