Installation within floor with Fire Batt (Weichschott) sealing
Refer to the section for further information.
Comply with the minimum distances indicated on section Minimum
distances
Floor opening
A opening must be provided in the floor as indicated in the table
and in the drawing
Damper positioning
Position the damper in the opening so that the side of the closing
mechanism extends as indicated in the table and in the drawing.
Filling
Fill the space between the damper and the floor using Fire Batt
(Weichschott) sealing made from two rock wool panels with mini-
mum thickness of 50 mm and minimum density of 140 kg/m³.
The panels must be covered on both faces of the wall with endo-
thermic varnish type PROMASTOP E PASTE or HILTI CFS-CT (mini-
mum thickness of 1 mm) and with an internal perimeter sealant type
PROMASTOP E PASTE or HILTI CFS-S ACR (minimum thickness of 1
mm).
