The gap 67 mm between dampers can be filled by
mineral stone wool min. density 140 kg/m³. Wool
is fixed to damper body by fire protection mastic.
Installation opening has to be
reinforced by steel U-profile.
Profile is fixed by screws
≥3,5 mm with corre-sponding
length. Distance between
screws ≤200 mm.
