Actionair DWFX-F Installation Guide
Vertical Damper Installation (Top
Flange removed) in a Plasterboard
Wall under Concrete Slab
Actionair SmokeShield PTC - [AA/F11945]
Actionair FireShield - [AA/F 11944]
Installation Method
1. Measure the overall Fire damper casing size w x h, but
for Smoke Shield include the PTC Shroud (28mm) in
the width but do not include any of the peripheral
flange.
2. Calculate the hole size...
3.
For Fire Shield calculate the finished hole size by adding
10-60mm to the case width and 5-30mm 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 10-30mm to the height as
the head of the damper will be against the slab.
5. Calculate the hole to cut size by adding two board
thicknesses to the finished hole width and only one for
the height.
6. Mark out the hole on the partition and cut it out.
7. Frame out the hole sides and bottom with stud and
track and cover this with board. Finish edges with joint
filler.
8. Drill clearance holes in the three damper flange sides at
150mm centres and such that they will allow screws to
pull into the stud and track around the hole.
9. Apply a bead of low pressure intumescent mastic
along top edge of damper as a gap filler and Install the
damper and fasten.
10. Back fill with mineral/stone wool and pattress over
this down to the spigot. Fasten with drywall screws
at 300mm centres on the sides and bottom such that
they will allow screws to pull into the stud and track
around the hole. Fix the top pattress into the track at
the sides.
11. 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. Alu-
minium rivets or plastic cleats, clips, clamps and bolts
etc. should be used for this, unless fire resisting duct-
work is being used where fire resisting fixings should
be used. A minimum separation of 200 mm between
fire dampers installed in separate ducts and 75mm bet -
ween fire damper and a construction element (ie wall/
floor) unless otherwise tested.
12. Alternative partition systems to those shown within
this installation manual can be used if they have been
shown by test to have at least the same fire resistance
when tested to BS EN 1364-1:1999 as is required of
the damper. If the partition system has been success-
fully tested without stone mineral wool it does not
have to be used in practice when only considering the
fire performance of the complete system. The mineral
wool may still be needed for other reasons e.g. acous-
tic performance.
13. For SmokeShield installations, please reference the
actuator installation information on page 11.

that shown here, please discuss this with the
Building Control Authority (BCA), referencing
this documentation, associated fire tests,

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).
