The
opening
must be ‘lined out’.
Cut size = damper size + (2 x nominal gap size) + (2 x wall board thickness).
E.g. for 150mm dia. damper, and 12.5mm wall board, cut aperture should be
195mm (150+(2x10)+(2x12.5))
Mark out position and size of required cut size on the wall.

Using appropriate means (e.g. jig saw), cut the aperture in the wall, removing
each layer and any
stud/track
that is present
Cut 2 pieces of steel track 50mm+ longer than opening size.
Fit track to top and bottom of opening, screwing in position from both sides
of wall at each end of track with drywall screws and at maximum 300mm
centers.
Cut 2 more pieces of track, this time, equal opening size.
Fit track to sides of opening, screwing in position in a similar fashion as
above.
6.10 Cut 4 pieces of
dry wall material
width to line the opening to the full width of the wall.
Screw each baton with 2 screws to the track that is lining the opening.
Ensure the access side baton is flush with the surface of the wall. Position
the damper centrally in wall opening (width/height),
Using drywall
screws, fix
Installation Plate to wall using drywall screws.
Important:
Ensure the screws
‘pick up’ the track lining the
aperture so that the proper fire integrity of the installation will not be
compromised. Use either one of the two appropriate Ø5mm corner fixing
holes and all Ø5mm mid-span fixing holes. Note for damper sizes of 100mm
– 200mm dia, the mid span fixing behind the fitted actuator, can be omitted.
Masonry wall and floor installation (Refer to FSD-C M10)
6.12 Preferably, prepare opening whilst building wall
/floor
, or cut opening if
wall
/floor
already exists.
6.13 Cut size = finished size
6.14 E.g. for 250 dia. damper, cut aperture should be 270mm square (250+20)
6.15 Mark out the position and size of opening on the wall
/floor
.
6.16 Using appropriate means, cut the aperture in the wall

There are a variety of proprietary fixings available. Fixings must be fire rated
(steel, NOT aluminum or plastic). Check minimum dimension specification
between fixing and edge of opening. BSB recommend
Tackburn Loden
anchors
.
Position the damper centrally in wall opening (width/height), with blade axle
running horizontally. Using steel screws, fix Installation Plate to wall
Important:
Use either one of the two appropriate Ø5mm corner fixing holes and
all Ø5mm mid-span fixing holes. Note for damper sizes of 100mm – 200mm
dia, the mid span fixing behind the fitted actuator, can be omitted.

Parts required and checks.
7.1.1 Damper.
7.1.2 Clamp plate attached to damper.
7.1.3 ST4.8mm dia x 19mm long safety self-tapping blunt point screws (quantity
to suit damper size). These are optional accessories at the time of purchase
of dampers.
7.2
Prepare and install damper into position.
7.2.1 Remove the clamp plate from the damper. The clamp plate will be screwed
in the corners of the damper frame for transportation.
7.2.2 One pair of M10 threaded drop rods are required to be suitably fixed to the
structure to hang vertically in a fire-safe manner to fully support the weight
of the damper. There is no limit on drop rod length.
Obscured fixing hole behind
actuator (see 6.11)
38mm long drywall screws to affix installation
