with the roof surface, and install the required roof flashing. Place the smoke exhaust fan on the roof fan
base with a gasket between the roof base and the smoke exhaust fan bottom. The equipment is
fastened with 4 bolts at the fan bottom corners.
Connecting the smoke exhaust fan to the (smoke exhaust) ventilation system:
Use type KD flexible joints, which need to be fastened to the smoke exhaust fan to reduce the vibration
transmission to the ducting.
This assembly is installed by sealing the joint interfaces [with high-temperature silicone] and tightening
the two parts with the bolts sized according to the fan size. The ventilation duct must not exert loads on
the smoke exhaust fan or other components of the assembly. The ventilation duct must be supported by
independent bearing slings. Secure the smoke exhaust fan suction intake with type SO safety mesh.
When installing the smoke exhaust fan, secure the installation site and all involved structures, and
prepare passage and access ways for all personnel not involved in the installation. The smoke exhaust
fan must be assured to enable inspection and servicing.
