Connect the round ductwork (not included) to the damper/duct connector, and run
the ductwork to a roof or wall cap (not included).
Using tape (not included), secure all the ductwork connections so that they are air
tight. The ducting from this fan to the outside of building has a strong effect on the
air flow, noise and energy use of the fan. Use the shortest, straightest duct routing
possible for best performance, and avoid installing the fan with smaller ducts than
recommended. Insulation around the ducts can reduce energy loss and inhibit mold
growth. Fans installed with existing ducts may not achieve their rated air flow.
