INSTALL THE HOUSING
- PLEASE NOTE -
THE FOLLOWING INSTALLATION ILLUSTRATIONS SHOW 2 X 6 JOISTS. IFYOU HAVE ATRUSS OR “I”-JOIST INSTALLATION, MOUNT THE VENTILATOR TO THE ADDITIONAL FRAMING IN THE SAME MANNER. (Additional framing must be a 2x6 (minimum height).
Existing Construction
1.Choose the location for your fan/light in the ceiling. For best possible performance, use the shortest possible duct run and a minimum number of elbows.
New Construction
HOLES
TAB
1-1/4

5/8
BOTTOM EDGE OF JOIST
1.Choose the location for your fan in the ceiling. For best possible performance, use the shortest possible duct run and a minimum number of elbows.
2.Position mounting brackets against joist so that bottom edge of housing will be flush with finished ceiling.
Additional positioning feature for 5/8”, 1”, & 1-1/4” thick ceiling material:
Holes in corners of housing are labeled with various ceiling material thicknesses. Position housing so bottom edge of joist is visible through a matched set of holes. The housing is now in the proper position for that ceiling material thickness.
Additional positioning feature for 1/2” thick ceiling material:
Bend two tabs, on side of housing, 900 outward. Lift housing until tabs contact underside of joist.
Mark the keyhole slot on both mounting brackets.
3.Set housing aside and drive nails partially into joist at the top of both keyhole marks.
4.Hang housing from
nails and pound nails tight. To ensure a noise-free mount, pound another nail through the top hole of each mounting tab.
2.In attic, position mounting brackets against joist. Trace outline of housing on ceiling material.
3.Set housing aside and cut ceiling opening slightly larger than marked.
4.Place housing in opening so that its bottom edge is flush with finished ceiling. Nail to joist through keyhole on both sides.To ensure a noise-free installation, drive another nail through the top hole of each mounting bracket.
RECOMMENDED: SEAL BETWEEN CEILING MATERIAL & HOUSING (4 SIDES)
ADDITIONAL
MOUNTING
HOLES
5.Additional mounting holes are provided for installations where access from above is inconvenient or not possible. Nail or screw housing directly to joists or framing.
Recommended: Seal between ceiling material & housing on all 4 sides to prevent air leakage.

INSTALL THE DUCTWORK
FLUSH
NOTE: The duct connector has a counter-balanced damper flap. The flap will be “open” approx. 1” when duct connector is attached to housing. This design permits insulation to be in direct contact with fan/light housing per UL (Underwriters Laboratories) standards. The slightest backdraft, however, will close the damper flap, preventing air from entering unit or finished space.
1.Snap the damper/duct connector onto housing. Make sure that tabs on the connector lock into slots in housing.Top of damper/duct connector should be flush with top of housing.
2.Connect 4” round duct to damper/duct connector and extend duct to outside through a roof or wall cap. Check damper to make sure that it opens freely. Tape all duct connections to make them secure and air tight.
