5. Insulation
Insulate the duct to an approved method according to the insulation supplier’s instructions.
Note that the insulation must cover the whole damper.

fitted with protection grilles on the non-connected side. The minimum permissible distance between the damper blade in the open
position and the grille is 50 mm.
