INSTALLATION INFORMATION
Connection of ventilation ducts
The fire dampers must be connected to the ventilation system
by means of ventilation ducts either on one or on both sides.
When connected on one side, finishing protective gratings
made of non-flammable building materials (EN13501-1) must
be provided on the opposite side. The fire dampers can be con-
nected to non-flammable as well as flammable ventilation
ducts. Ventilation ducts must be suspended separately.
The local regulations or national standards on ventilation sys-
tems (in Germany e.g. LüAR) apply. It is important that ventila-
tion ducts do not exert significant forces on walls, supports or
ceilings and thus also on fire dampers as a result of thermal
expansion (in case of fire). Appropriate compensation
measures, such as the arrangement of flexible spigots or a suit-
able duct routing (duct angles and distortions), must be taken
as required. National regulations must be observed and ad-
hered to.
