Reduced installation plate.

 

8.2.2 

The installation plate is recommended to be supplied ‘factory cut. All four sides can be supplied cut down 

         where required.

A length of steel supporting angle should be affixed to the top of the opening as shown in fig.  5 

8.2.4 

The damper should be installed within and affixed to the top supporting angle. 

8.2.5 

Fire batt material should be cut to suit void with zero clearance to produce an interference fit. The 
installation  

         

plate face, and all edges should be ‘glued’ in place, and a bead of intumescent mastic applied at all joints.  

8.2.6 

Note 

– two layers of 50mm min thickness are required to comply with the ‘as tested’ installation method. 

8.2.7 

Screw-in 50mm long spiral (pig tail) fixings through installation plate into batt material utilising one of the pair   

                        of corner holes, and all intermediate fixing holes. (It may be necessary to drill additional fixing holes  
                        depending on plate size reduction). 

8.2.8 

Recommended minimum void gap (per side) is 40mm and maximum 600mm. 

 

8.3 

Overlapping installation plate installation (refer to fig 6) 

8.3.1 

It is permissible to overlap the installation plate with another installation plate where two dampers  are near to 
each other. 

8.3.2 

The two overlapping plates should be secured together by drilling 3.2mm dia holes and using  steel rivets 
mirroring the existing fixing pitches. 

8.3.3     

Screw-in 50mm long spiral (pig tail) fixings through installation plate perimeter into batt material  utilising one of 

the pair of corner holes, and all intermediate fixing holes
