Installation sequence
4
Install 40mm x 40mm x 4mm angle through the AFS brackets ensuring they are of sufficient length to
extend past the opening on each side by 100mm.
5
Position the dampers evenly in the centre of the opening.
6
Secure the angles to the floor. Mark the hole positions on the angle at least 50mm away from the
opening. Drill and install M8 steel anchors and bolt the angle to the floor.
7
The galvanised mild steel ductwork connecting to the damper spigot must overlap by 40mm, leaving
a 10mm clearance for any duct expansion in a fire situation.
8
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.
9
‘Z’ angles are required to support the first layer of fire batt. These measure 50mm x 150mm x 50mm
by 100mm wide. They are to be positioned on all fire batt joints on the bottom layer and evenly spaced
on a 500mm minimum pitch.
10
The gap between the damper and the floor opening will need filling with three layers of 50mm thick
140kg/m
3
fire batt cut to an interference fit and pushed into 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.
11
The connecting galvanised mild steel ductwork must be independently supported within one metre of
the connections and have been installed in accordance with DW144.
12
An access door should be fitted on the access side of the damper for inspection and maintenance.
13
When the damper installation is complete the operation of the damper should be checked.
