Preparing the opening
1
Ensure that the damper is kept
in a clean dry environment and
that there is no damage to the
damper.
2
Remove all the packaging and
transit ties before installation.
3
Work out the opening size to be
cut using the table adjacent.
Installation sequence
4
In the opening, mark the positions for the turnback tabs on the HEVAC frame.
5
Create 20mm deep pockets for the HEVAC tabs to be located in.
6
Offer up the damper into the opening and support from the bottom of the damper so that it sits
centrally within the opening and has an even space on all four sides.
7
Bend the HEVAC tabs so that they lock into the pockets.
8
A 4:1 mortar mix can then be gradually applied between the wall and the damper, ensuring the mortar
is only filled up to the HEVAC frame and not the damper spigots. This ensures the damper can move
within the HEVAC frame.
9
The galvanised mild steel ductwork connecting to the damper spigots must overlap by up to 40mm,
leaving minimum 10mm clearance for any duct expansion in a fire situation.
10
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.
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 has been completed, checks should be made to ensure the damper is
secure and there is no movement, operation of the damper should be checked.
14
