While we have tested a damper 2,000 x 2,000mm, larger sizes can be supplied in sections but the installation will need to be checked by a
competent structural engineer as stated in the Extended Fields of Applications BS EN 15882-2:2015. With all larger sizes there should be a risk
assessment carried out and a full method statement documented to ensure the correct lifting gear and safety precautions are in place prior to
the installation being carried out.

The multi-section damper will be supplied enclosed in one large casing up to a

maximum spigot size of 2,000mm.
The drywall will consist of two layers of 15mm plasterboard each side of steel studwork with an optional
50mm mineral wool insulation. The opening will be a letterbox construction with overlapping layers of
plasterboard with an opening clearance around the damper casing in line with the table above.
Two M10 drop rods shall be fitted on either side of the drywall. These should be securely installed in
line with the manufacturer's fixing instructions in a position to match the AFS rail.
The drop rods should have a nut screwed on for clamping the rail from above.
Slide the AFS rails on each side of the damper into the brackets and insert the "Z" piece into the
bracket slot pushing it up against the underside of the rail. Insert the 8mm bolt from above into the slot
through the "Z" piece fitting the nut until tight to secure the rail.
Additional drop rods should then be passed through the top and bottom rails and fully tightened.
The damper should be mounted centrally in the opening with the access side flush with the wall, as
detailed in the drawing. The drop rods are to slide through the slots in the rail and a nut screwed on
to take the support of the damper rail. The damper must then be levelled and when in the correct
position the nut above the rail should be tightened against the rail.
The galvanised mild steel ductwork connecting to the damper spigots must overlap by up to 40mm,
leaving a minimum 10mm clearance for any duct expansion in a fire situation.
The galvanised mild steel ductwork connections must be sealed with an approved galvanised mild
steel ductwork sealer and fixed with low resistance fixings such as aluminium rivets that will melt at
high temperature allowing the duct to break away without affecting the integrity of the installation.
The connecting galvanised mild steel ductwork must be independently supported within one metre of
the connections and have been installed in accordance with DW144.
The gap between the damper and the wall opening will need filling with two layers of 50mm thick
140kg/m3 fire batt cut to an interference fit and pushed in to place. All cut edges must be sealed with
a fire batt sealant to BS EN 13501-2. A fire rated intumescent mastic to BS EN 13501-2 shall be applied
to each joint.
An access door should be fitted on the access side of the damper for inspection and maintenance.
When the damper installation has been completed checks should be made to ensure the AFS rails are
secure and there is no movement, operation of the damper should be checked.
