Joist mounting installation
1. Preparation for mounting
Determine thickness* of finished ceiling board.
Place main body (A) against ceiling joist in desired location.
Ensure bottom of main body (A) hangs down below joist to account
for finished ceiling board.
NOTE:
If thickness of finished ceiling board is 3/4" (1.9 cm) then main body (A)
should hang down from joist 3/4" (1.9 cm).
2. Mounting fan body
Use wood screws (BB) to loosely attach both sides of main body
to joist.
Ensure ventilation fan is level and that proper clearance is given
for finished ceiling board.
When main body (A) is level and in the intended location, tighten
screws (BB) on both side of it.

Safety information and warnings
WARNING: TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK,
OR INJURY TO PERSONS, OBSERVE THE FOLLOWING:
16. Use this unit in the manner intended by the manufacturer. If you have
any questions, please call customer service.
17. Installation work and electrical wiring must be done by a qualifed
person in accordance with all applicable codes and standards,
including fire-rated construction.
18. Sufficient air is needed for proper combustion and exhausting
of gasses through the chimney (flu) of fuel burning equipment
to prevent back drafting. Follow the heating equipment manufacturers
guideline and safety standards such as those published by the NFPA
(National Fire Protection Association) and ASHRAE (American
Society for Heating Refrigeration and Air Conditioning Engineers)
and the local building code authorities.
19. Do not install in a ceiling with insulation greater than R40.
20. Be careful not to damage existing wiring when cutting or driling into
walls or ceilings. When cutting the ceiling, do not damage electrical
wiring and other hidden utilities.
21. Switch power off at service panel and lock the service disconnecting
means to prevent power from being switched on accidentally. When
the service disconnecting means cannot be locked, securely fasten a
prominent warning device, such as a tag, to the service panel.
22. If this unit is to be installed over a tub or shower, it must be marked
as appropriate for the application. When the fan is going to install in
the bathroom, the fan and the tub need to be more than 3' (1 m)
between each other, the fan required to install at the other side of the
tub in ceiling. Acceptable for use over a bathtub or shower when
installed in a GFCI protected branch circuit.
23. DO NOT use rigid conduit for the installation.
24. Duct work should be installed in a straight line with minimal bends.
25. Duct work size must be the same size as the discharge and should
not be reduced. Reducing the duct size may increase fan noise.
26. For CUL only: Mount with the lowest moving parts at least
8’ 2" (2.5 m) above floor or grade level.
