Sheet steel smoke extract duct (by others)
As ducts may expand in the event of a fire, we recom-
mend using flexible connectors at one end when con-
necting a sheet steel smoke extract duct which is
attached at both ends. The flexible connectors should
meet the specifications for the sheet steel smoke extract
duct. Be sure to follow the manufacturer's instructions.

If no smoke extract duct is connected to the smoke con-
trol damper, it will be necessary to protect the end with a
cover grille (accessory or to be provided by others:
galvanised steel, mesh aperture ≤ 20 mm).
