all applicable codes and standards, including fi re-rated construction codes and standards.
4. Suffi cient air is needed for proper combustion and exhausting of gases through the fl ue

manufacturer's guideline and safety standards such as those published by the National Fire
Protection Association (NFPA), and the American Society for Heating, Refrigeration and Air
Conditioning Engineers (ASHRAE), and the local code authorities.

8. Install fan at least fi ve feet (1.52 m) above the fl oor.
9. Never place a switch where it can be reached from a tub or shower.
10. This unit must be grounded.
INSTALLATION
1. Remove motor plate from housing by pushing down on rib in plate while pulling out
on side of housing. Motor plate may also be removed by inserting a straight-blade
screwdriver into slot in housing and twisting screwdriver (FIG. 1).
2. Remove wiring cover from housing by pulling straight out. Unit is shipped ready
to wire through the top of housing. To wire through the side, bend housing flap to
cover top hole and expose side hole. DO NOT BREAK OFF FLAP. If flap breaks,
Plug unused hole using standard electrical hole plug (FIG. 2).
3. Turn off electrical power at service entrance and connect power cable to housing
using appropriate connector. Wire black to black, white to white, and green to green
or bare wire.
Push all wiring up into corner of unit and replace wiring cover. Make sure cover
holds housing flap in place against side or top of housing.
CAUTION: DO NOT ALLOW WIRES TO EXTEND OUTSIDE OF WIRING BOX.
Wire left exposed will become pinched or cut when motor plate is installed.
Electrical shock may result (FIG. 3).
4. Choose the location for your fan. For best performance, use the shortest possible
duct run and a minimum number of elbows. For wall installations: Position unit so
damper flap closes when unit is off.
5. New installation prior to finishing the ceiling or wall:
MAKE SURE HOUSING WILL BE FLUSH WITH FINISHED CEILING OR WALL.
Slotted tabs are provided to locate housing flush with 1/2" ceiling or wall material.
Bend tabs outward 90° (use a screwdriver if desired) and position housing so that
tabs rest against bottom edge of joists (or front of stud). Nail housing to joist or stud
using four nails to ensure a solid, quiet installation. Ceiling installations: Tabs on
opposite side of housing can be bent outward to rest on top of 1/2" ceiling material
and provide extra stability (FIG. 4).
5. Replacement installation:
Position housing so that it is centered in existing opening. MAKE SURE HOUSING
IS FLUSH WITH FINISHED CEILING OR WALL. After making electrical and
ductwork connections (see steps 4, 5 and 6), nail housing in place. Drive nails
through the housing where indicated by arrows (FIG. 5).
5. New installation in an existing ceiling or wall:
From above ceiling or behind wall, position housing against stud or joist. Trace
outline of housing on ceiling or wall material (FIG. 6). Set housing aside and cut
opening. Place housing in opening such that its BOTTOM EDGE IS FLUSH WITH
FINISHED CEILING OR WALL. 1/2" ceiling or wall material: Bend tabs outward 90°
(use a screwdriver if desired) to rest on top of ceiling or wall material and provide
extra stability. Nail in place using four nails to ensure a solid, quiet installation (FIG. 7).
6. Install 3" round duct onto damper/duct connector. If rigid ductwork is used, its seam
should be positioned at top of damper/duct connector. Tape the joint and extend
ducting to a wall cap or roof cap. Make sure the damper operates freely. Ceiling or
wall can now be finished.
NOTE: If damper detaches from duct connector, re-insert it by squeezing duct
connector top-to-bottom while guiding posts on damper flap into holders in duct
connector. The horizontal rib should be on the outside surface of damper flap
and damper flap should move freely inside of duct connector.
7. Replace the motor plate removed in Step 1. Insert two motor plate tabs into slots
in housing and then pivot motor plate up until the third tab on plate snaps into
matching slot in housing. Make sure tabs hold motor plate securely in place. Plug
in motor (FIG. 8).
8. Squeeze grille springs together and insert springs into slots in motor plate (FIG. 9).
Push grille up against ceiling or wall (FIG. 10).

cloth. DO NOT USE ABRASIVE CLOTHS, STEEL WOOL PADS, OR SCOURING POWDERS.
TO CLEAN FAN ASSEMBLY - Unplug motor cord from receptacle. To remove motor plate:
Find the single tab on the motor plate (located next to the receptacle). Push up near motor
plate tab while pushing out on side of housing. Or insert a straight-blade screwdriver into
slot in housing (next to tab) and twist screwdriver. Gently vacuum fan, motor and interior
of housing. METAL AND ELECTRICAL PARTS SHOULD NEVER BE IMMERSED IN WATER.
