Connecting the ductwork
When you connect ducts to the fire damper, keep the
following in mind:
Connect calcium silicate smoke extract ducts
according to the manufacturer's instructions.
The interior of the fire damper must remain acces-
sible for repairs. Depending on the installation con-
figuration it may be necessary to provide inspection
panels in the connecting ducts.
Sheet steel ducts may be connected but require a
connecting subframe (one side or both sides).
Ducts may be connected without any flexible con-
nectors.
Any side on which no duct is to be connected
requires a cover grille as a safety guard and as a
protection against birds etc. (galvanised steel, mesh
aperture ≤ 20 mm).
