Installation
of a rectangular fire damper
PKIS3G
on a wall
and
out of a wall
- fire resistivity EI60S
NOTES: This picture is valid for
L
D
= max. 1500 mm from
the damper’s ending. For
L
D
> 1500 mm the maximum
spacing between threaded rods must be max. 1500 mm
and one more point of suspension must be added as
close as possible to the connection flange.

** Along the insulated duct - the first stiffening rod is placed
inside the wall. Each subsequent stiffening rod must be placed
with an

distance = max. 1000 mm. The last stiffening rod must
be placed 1000 mm from the fire damper flange at most. If the
fire damper flange is closer to the wall than the overhang of the
open blade (

; see Tab. In TechSpec_TPI-28...), then move the
first stiffening rod to the right so that the distance between the
stiffening rod and the fire damper flange is
