SECTION 1

Preparing the Exhaust Fan

1. Unpack fan from the carton and confirm that all pieces are
present. In addition to the exhaust fan you should have:

1 - Grill with Light Lens
1 - Damper Assembly (attached)
2 - #8 Screws
4 - Mounting Rails
1 - Instruction/Safety Sheet

2. Remove the fan’s venturi assembly, which is secured in place
with one screw through the venturi (Figure 1). This is a captive
screw and will stay installed in the venturi. Keep the venturi
assembly and the grill in the carton until needed so they do
not get damaged or lost.

2. Mounting Tab Installation: Using the gauge on the fan’s
housing, line up housing so that it will be flush with the
finished ceiling. Position the fan so that the tabs rest flat
against the joist and secure with four nails or screws (not
provided) to ensure proper installation (Figure 4).

3. Choose the location for your fan. To ensure the best air and
sound performance, it is recommended that the length of
ducting and the number of elbows be kept to a minimum, and
that insulated hard ducting be used. Larger duct sizes will
reduce noise and airflow restrictions. This fan will require at
least 6" of clearance in the ceiling or wall, and will mount
through drywall up to 3/4" thick. The
fan can be mounted directly to the
joist using the mounting tabs on the
sides of the housing or between 16"
on center joists using the 4 provided
mounting rails.

4. Select the most convenient
electrical knockout and remove
using a straight-blade screw driver
(Figure 2).

SECTION 2

New Construction

1. Side Rail Installation: Install the side rails on the housing
and position the housing next to the joist. Using the gauge
on the fan’s housing, line up housing so that it will be flush
with the finished ceiling. Secure the ends of the rails with
screws or nails (not included) to the joists and slide the
housing into the final position (Figure 3).

Figure 4

SECTION 3

Existing Construction

1. Side Rail Installation: Set housing in position between the
joist and trace an outline onto the ceiling material (Figure 5).
Set housing aside and cut opening, being careful not to cut
or damage any electrical or other hidden utilities. Install the
side rails on the housing and position the housing in the
previously cut hole so that it is flush with the finished ceiling.
Secure the ends of the rails to the joists (Figure 3).

Figure 5

1. Mounting Tab Installation: Position housing against the joist
and trace an outline of the housing onto the ceiling material
(Figure 6). Set housing aside and cut opening, being careful
not to cut or damage any electrical or other hidden utilities.
Place housing next to the joist and insure that it is flush with
the finished ceiling. Secure with four screws or nails (not
provided) to ensure proper installation (Figure 4).

Ducting

CAUTION: ALL DUCTING MUST COMPLY WITH LOCAL

AND NATIONAL BUILDING CODES.

1. Connect the ducting to the fan’s duct collar (Figure 7). Secure
in place using tape or screw clamp. Always duct the fan to
the outside through a wall or roof cap.

collar back onto the unit. It is designed to only fit one way.

SECTION 5

Wiring

CAUTION: MAKE SURE POWER IS SWITCHED OFF AT

SERVICE PANEL BEFORE STARTING INSTALLATION.

CAUTION: ALL ELECTRICAL CONNECTIONS MUST BE

MADE IN ACCORDANCE WITH LOCAL CODES, ORDINANCES,
OR NATIONAL ELECTRICAL CODE. IF YOU ARE UNFAMILIAR
WITH METHODS OF INSTALLING ELECTRICAL WIRING, SECURE
THE SERVICES OF A QUALIFIED ELECTRICIAN.

1. Wiring Fan/Light Independently: Run wiring from an approved
wall switch carrying the appropriate rating. One neutral (white),
one ground (green or bare copper), and two hot (black lead
connected to the switch). Secure the electrical wires to the
housing with an approved electrical connector. Make sure
you leave enough wiring in the box to make the connection to
the fan’s receptacle.

1a. From where you have access to inside the fan’s junction box,

connect the one white wire from the house to both the white
wire from the fan’s light receptacle and the white wire from
the fan’s exhaust receptacle. Connect the first black wire from
the wall switch to the black wire from the fan’s light receptacle.
Connect the second black wire from the house to the fan’s
exhaust receptacle. Connect the ground wire from the house
to the green wire from the fan’s grounding screw (Figure 8).
Use approved methods for all connections.

Figure 8

2. Wiring Fan/Light together: Run wiring from an approved wall
switch carrying the appropriate rating. One neutral (white),
one ground (green or bare copper), and one hot (black lead
connected to the switch). Secure the electrical wires to the
housing with an approved electrical connector. Make sure
you leave enough wiring in the box to make the connection
to the fan’s receptacle.

2a. From where you have access to inside the fan’s junction

box, connect the one white wire from the house to both the
white wire from the fan’s light receptacle and the white
wire from the fan’s exhaust receptacle. Connect the black
wire from the wall switch to both the black wire from the
fan’s light receptacle and the black wire from the fan’s
exhaust receptacle. Connect the ground wire from the house
to the green wire from the fan’s grounding screw (Figure

9). Use approved methods for all connections.

Completing the Installation

1. Reinstall the fan’s venturi by holding it at approximately a 45
degree angle, hook the two tabs on the venturi into the slots
on the housing and secure in place by tightening the venturi
screw. Rotate the blower wheel by hand to ensure it spins
freely. Now plug the fan motor into the receptacle (Figure 10).

Figure 10

2. Install the grill/lens/light reflector, by first removing the lens
from the grill (there are two tabs on either side that hold the
lens in place). Plug cord from light socket into the appropriate
receptacle (Figure 11).
