CAUTION
Smoke extraction ducts should be made in accordance with the ducts manufacturer’s guidelines.
The ducts must have an adequate fire resistance rating in accordance with the fire resistance rating
provided for the entire solution. Seal all connections between the damper and the ducts with the
appropriate mortar/glue/gaskets, ensuring that the fire resistance rating is maintained. The smoke
control damper in vertical fire ventilation systems may be installed across the horizontal smoke
extract duct or on the sides of the horizontal smoke extract duct or on the surface of any side of
the vertical smoke extract duct. A masking grille may terminate the system.
