INSTALLATION INSTRUCTIONS

CAUTION:
SERVICE PANEL BEFORE STARTING INSTALLATION.
WARNING:
OR USE GASOLINE OR OTHER FLAMMABLE VAPORS AND LIQUIDS IN
THE VICINITY OF THE HEATER.
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
1 - Damper Assembly (attached)
4 - Mounting Rails
1 - Mounting Flange
1 - Instruction/Safety Sheet
2. 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,
the radius of each elbow be as large as possible for the installation, and that insulated
hard ducting be used. Larger duct sizes will reduce noise and airflow restrictions.
This fan will require at least 7¾" of clearance in the ceiling or wall (including drywall
thickness), and will mount through drywall up to ¾" thick.
3. No additional vibration deadening materials are needed for this fan.
SECTION 2
New Construction
1. Install the rails into the mounting channel on the housing. Center the mounting channel in
the slots on the housing, then from inside the housing tighten the mounting channel nuts
so the channel is securely in place. Position the housing next to the joist. 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 1).

SECTION 3
Existing Construction
1. Set housing in position between the joist and trace an outline onto the ceiling material
(Figure 2). Set housing aside and cut opening, being careful not to cut or damage any
electrical or other hidden utilities. Install the rails into the mounting channel on the
housing. Center the mounting channel in the slots on the housing, then from inside the
housing tighten the mounting channel nuts so the channel is securely in place. 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 1).

SECTION 4
Ducting
CAUTION:
NATIONAL BUILDING CODES.
NOTE: The ducting from this fan to the outside of the building has a strong effect on the air
flow, noise and energy use of the fan. Use the shortest, straightest duct routing possible
for best performance, and avoid installing the fan with smaller ducts than recommended.
Insulation around the ducts can reduce energy loss and inhibit mold growth. Fans installed
with existing ducts may not achieve their rated air flow.
1. Connect the ducting to the fan's duct collar (Figure 3). Secure in place using tape
or screw clamp. Always duct the fan to the outside through a wall or roof cap. It is
recommended that low restriction termination fittings be used.

Wiring
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. Remove the wire compartment cover inside the unit
by unscrewing the screw holding it in place. Set
aside in a safe place (Figure 4).
2. Remove the required electrical knockouts on the
wire compartment using a straight-blade screw driver (Figure 4).
3. Run a ground wire from the power source to the wire compartment and connect to the
green ground wire inside the compartment. Run a White (Neutral) wire from the power
source to the wire compartment and connect to the three (3) white wires inside the
compartment. Run five (5) hot wires from the wall switches (not included) to the wire
compartment. Make all the wire connections as follows:
Wall Switch: Connect the hot wire that will energize the wall switches to the orange
wire from the wire connector in the wire compartment. Additional jump wires may be
need at the wall switches depending on the type and style of switches used.
Heater Function: Connect one of the hot wires from the wall switch to the yellow wire
from the wire connector in the wire compartment.
Fan Function: Connect one of the hot wires from the wall switch to the black wire from
the wire connector in the wire compartment.
Light Function: Connect one of the hot wires from the wall switch to the blue wire from
the wire connector in the wire compartment.
Night Light Function: Connect one of the hot wires from the wall switch to the red wire
from the wire connector in the wire compartment (Figure 5).
