Installation
• The PKI-C re damper is installed into the duct, in the place where the re-proof wall is, or at the end of the duct
in front of an air valve or a similar outlet.
• The duct that holds the re damper must be supported or hung in such a way that the crossing does not carry its
weight. The crossing must not support any part of the surrounding construction or wall which could cause damage
and consequent damper failure.
• According to the standard EN 1366-2, the distance between ducts that hold PKI-C or between other objects
that cross the supporting construction must be at least 200 mm.
• The distance between the wall/ceiling and the duct that holds PKI-C must be at least 75 mm.
• The re damper is embedded into the re partition construction into duct in such a way that when the damper
blades are in the CLOSED position, that will be entirely situated inside the wall.
• The gap in the installation opening between the re damper and the wall/ceiling can be increased by up to 50%
of the gap area.
• The gap in the installation opening between the duct that holds PKI-C and the wall/ceiling can be decreased
to the smallest amount possible that still provides sufcient space for the installation of the seal.
• All PKI-C dampers can be installed with the blade axis in a horizontal position or a vertical position.
• Lists of all permitted installation methods are provided on following pages. Every method only applies
to those damper types that are listed in the corresponding paragraph’s heading.
