1. Prepare the duct connection or opening as per Fig. 43, clean and atten the connecting surface.
2. Apply a re resistive coat (8) on the connection surfaces as depicted in the detail in Fig. 43.
3. Connect the damper’s ange (on the blade side) to the duct as per the
“Fixing the S-SA2L Smoke Damper”
section.
4. From boards (4 and 5) create a collar overlapping the connection as depicted in Fig. 43.
5. Fix the overlapping collar to the damper with screws (5). Fix the collar to the duct by using screws
as per instructions of duct system manufacturer.
IMPORTANT: The opening dimensions must be created according to the details of each type
and thickness of the connected duct.
The re resistivity of the S-SA2L smoke damper must be decreased to the duct performance.
The maximum resistivity for L2V installation is EI120S with pressure level 3 (-1500 Pa … 500 Pa).
