Fire batt
Preparation
1
Ensure the that damper is kept in a clean dry
environment and that there is no damage to the
damper.
2
Work out the opening size to be cut by adding
55mm to the duct diameter and cut a square hole to
that size, see adjacent table.
Installation sequence
3
The damper should be mounted in the opening with the fixing flange (access side) flush with the wall.
4
Confirm that the blade is horizontal, and the handle is on the RH or LH. The flange can then be secured
to the wall using fire resistant steel fixings. Ensure that all the pre-drilled holes are populated.
5
The gap between the damper and the wall opening will need filling with two layers of 50mm thick
140kg/m
fire batt cut to interference fit and pushed into place. All cut edges must be sealed with a
3
fire batt sealant to BS EN 13501-2. A fire rated intumescent mastic to BS EN 13501-2 shall be applied to
each joint.
6
The galvanised mild steel ductwork connecting to the damper spigots should overlap by 30mm,
leaving a 10mm clearance for any duct expansion in a fire situation.
7
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.
8
The connecting galvanised mild steel ductwork must be independently supported within one metre of
the connections and have been installed in accordance with DW144.
9
An access door should be fitted on the access side of the damper for inspection and maintenance.
10
When the damper installation is complete the operation of the damper should be checked.
