Actionair DWFX-F Installation Guide
Vertical Damper Installation (Top
Flange Remo ved) In A Masonry Wall
Under Concrete Slab
Actionair SmokeShield - [AA/F12394]
Actionair FireShield - [AA/F12827]
Installation Method
1. Measure the overall Fire damper casing size width x
height, but for Smoke Shield include the PTC Shroud
(28mm) in the width but do not include any of the
peripheral flange.
2. Calculate hole size...
3.
For Fire Shield calculate the finished hole size by adding
10-80mm to the case width and 5-40mm for the
height as the head of the damper will be against the
slab.
4.
For Smoke Shield calculate the finished hole size adding
10-57mm to the width and 5-30mm to the height as
the head of the damper will be against the slab.
5.
Drill clearance holes in the three damper flange's side
and bottom at 150mm centres.
6. Apply a bead of low pressure intumescent mastic
along top edge of damper as a gap filler and install
the damper and fasten through flange using fire rated
fasteners, min ø4mm.
7.
Dampers are supplied with cleats and only need to be
used to help/assist with the installation before faste
-
ning the flange to the wall.
8.
Back fill with mineral/stone wool and to retain this use

Description:
If your proposed installation details differ from
that shown here, please discuss this with the
Building Control Authority (BCA), referencing
this documentation, associated fire tests,
assessments, and other documentation shown
below. Deviation from this drawing requires
the approval of the relevant authority.
Installation Detail
Connecting ductwork omitted for clarity.
Ductwork must be independently supported.
There must be an appropriate break-away
joint between the damper and connecting
ductwork on both sides of assembly.
Aluminium rivets or plastic cleats, clips,
clamps and bolts etc. should be used for this,
unless fire resisting ductwork is being used
where fire resisting fixings should be used. A
minimum of 200 mm construction element
(wall) between fire dampers installed in
separate ducts and 75 mm between fire
damper and a construction element (wall).

installed in separate ducts and 75 mm between fire
damper and a construction element (wall/floor).
