1. Housing mounted to joists (start at "Assembly Instructions 1" below)
2. Mount with Mounting Holes and Hanger Bar
Slide one hanger bar into the channel on the housing and adjust as
needed to fit between framing. Hold housing in place so that the
housing contact the bottom of the joist. Screw housing to joist through
the hole A and hole B. Screw the hanger bar onto the other side of joist
through the hole (refer to the diagram on the right). Screw hanger bar
to housing with screw A.
The Choice of Hanger Bar
3. Mount with Hanger Bars Only
Slide hanger bars onto housing and adjust as needed to fit between
framing. Extend the hanger bars to the width of the framing. Position
the fan with the hanger bar tabs wrapped around the bottom edge of
the framing, holding the fan in place. Secure hanger bars to framing
using one screw on each end of hanger bar (refer to the right diagram).
Screw hanger bar to housing with screw A.
The Choice of Hanger Bar A
4. Mount to I-joist
Slide one hanger bar (long) into channel B on the housing and adjust as
needed to fit between framing. Hold housing in place so that the
housing contacts the bottom of the joist. Screw housing to joist
through the hole A and hole B. Screw the hanger bar onto the other
side of joist through the hole (refer to the right diagram). Screw hanger
bar to housing with screw A.
5. Install Round Ductwork
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 airtight. Insulated flexible duct is recommended for the
quietest possible installation. If rigid duct is used, a short (1-3ft) section
of insulated flexible duct will ensure quiet operation.
The ducting from this fan to the outside of building has a strong effect
on the airflow, 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.
