Preparing the Exhaust Fan

5. Select the most convenient
electrical knockout and remove
using a straight-blade screw driver
(Figure 3).

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)
4 - Mounting Rails
1 - Instruction/Safety Sheet

2. Remove the fan’s light reflector, which is secured in place
with one center located screw. Also remove the lock washer,
washer and flat washer. Keep all parts in the carton until
needed so they do not get damaged or lost (Figure 1).

with one screw through the venturi. Keep the venturi assembly
in the carton until needed so it does not get damaged or lost
(Figure 2).

New Construction

1a. Slide Rail Installation: Install the slide rails on the housing

and position the housing next to the joist with the transition
plate flush to the underside of the joist. Secure the ends of
the rails with screws or nails (not included) to the joists and
slide the housing into its final position (Figure 4).

4. 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 side of
the housing or between 16" on center joists using the 4
provided mounting rails.

1a. Slide Rail Installation: Set housing in position between the

joist and trace an outline 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. Install the
slide 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 with screws or nails (not included)
to the joists (Figure 4).

Figure 6

1b. Mounting Tab Installation: Position housing against the joist

and trace an outline of the housing onto the ceiling material
(Figure 7). 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 5).

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 9). Use approved methods for all connections.

SECTION 4

Ducting

CAUTION: ALL DUCTING MUST COMPLY WITH LOCAL

AND NATIONAL BUILDING CODES.

1. Connect the ducting to the fan’s duct collar (Figure 8). Secure
in place using tape or screw clamp. Always duct the fan to
the outside through a wall or roof cap.
