1. Prepare the duct connection or opening as per Fig. 36 - Fig. 41, clean and atten the connecting surface.
2. Apply a re resistive coat (3) on the connection surfaces as depicted in Fig. 36 - Fig. 41.
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 7) create a collar overlapping the connection as depicted in Fig. 36 - Fig. 41.
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 L1V installation is EI120S with pressure level 3 (-1500 Pa … 500 Pa).
