Smoke damper
rev 21-10
Preparations:
• Cut ducts at right angles.
• Carefully remove any burrs from cut edges. Installation is
easier and the risk of damaging the gasket is reduced if there
are no burrs.
• Cut away the needles created from the fold.
Assembly
• Start by inserting the turned-over edge of the damper into
the duct.
• Check that the fi rst lip of the gasket is in contact with the
edge of the duct all the way around and sticks straight out so
that the lip is not twisted in one direction or the other.
• Push the end of the damper into the duct. Twisting the
damper slightly aids insertion.
• Secure the damper in the duct using self-tapping screws
Ø4,2×13.
• Fasteners should be positioned on the duct close the damper
(minimum 10-15 mm) to support itself weight and to prevent
damage to the gasket.
• The damper must be installed on certifi ed and CE marked
smoke control system.
