GENERAL SAFETY INFORMATION

When using electrical appliances, basic precautions

should always be followed to reduce the risk of fire,

electric shock and injury to person, including the following:

WARNING: TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK AND

INJURY TO PERSON, OBSERVE THE FOLLOWING:

a) Use this unit only in the manner intended by the manufacturer.If you have

questions, contact the manufacturer.

b) Before servicing or cleaning the unit, switch power off at service

panel and lock the service disconnecting means to prevent power
from being switched on accidentally. When the service disconnecting
means cannot be locked, securely fasten a prominent warning
device, such as a tag, to the service panel.

WARNING: TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK AND

INJURY TO PERSON, OBSERVE THE FOLLOWING:

a) Installation work and electrical wiring must be done by qualified

person(s) in accordance with all applicable codes and standards,
including fire-related construction.

b) Sufficient air is needed for proper combustion and exhausting of

gases through the flue (chimney) of fuel burning equipment to prevent
back drafting. Follow the heating equipment 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.

c) When cutting or drilling into wall or ceiling, do not damage electrical

wiring and other hidden utilities.

CAUTION: FOR GENERAL VENTILATING USE ONLY. DO NOT USE TO

EXHAUST HAZARDOUS OR EXPLOSIVE MATERIALS AND VAPORS.

d) Ducted fans must always be vented to the outdoors.
e) This unit must be grounded.
f) To avoid motor bearing damage and noisy and/or unbalanced impellers,

keep drywall spray, construction dust, etc. off power unit.

g) Read all instructions before installing or using exhaust fan.

WARNING: TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, DO NOT

USE THIS FAN WITH ANY SOLID-STATE SPEED CONTROL DEVICE.

a) If this unit is to be installed over a tub or shower, it must be

marked as appropriate for the application and be connected to a
GFCI (Ground Fault Circuit Interrupter) – protected branch circuit.

WARNING: DO NOT USE IN KITCHENS.
WARNING: 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 AIRFLOW.

INSTALLATION INSTRUCTIONS
CAUTION:

STARTING INSTALLATION.

MAKE SURE POWER IS SWITCHED OFF AT SERVICE PANEL BEFORE

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 - 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. This fan will require at least 8"
of clearance in the ceiling or wall, and will mount
through drywall up to 3/4" thick. The fan mounts
between 16” or 24” on center joists using the 4
provided mounting rails.

3. Select the most convenient electrical knockout and
remove using a straight-blade screw driver (Figure 1).

4. No additional vibration deadening materials are
needed for this fan.

Figure 1

SECTION 2

New Construction

1. Install the side rails on the housing and 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 2).

SECTION 4

Ducting

NOTE: 4" OR LARGER RIGID DUCT IS RECOMMENDED FOR BEST PERFORMANCE.

CAUTION: ALL DUCTING MUST COMPLY WITH LOCAL AND 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 4). 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.

2. Ensure duct joints and exterior penetrations are sealed with caulk or other similar
material to create an air-tight path to minimize building heat loss or gain and to reduce
the potential for condensation. Place/wrap insulation around duct and/or fan in order to
minimize possible condensation buildup within the duct, as well as building heat loss or
gain (Figure 5).

SECTION 3

Existing Construction

1. Set housing in position between the joist and trace an outline onto the ceiling material

(Figure 3). 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 2).

SECTION 6

Completing the Installation

1. Use a sealant appropriate for contact with the building materials present and for the

temperature requirements of the installation to prevent air leakage from unconditioned
spaces is recommended. If gaps between unit housing and ceiling are great, additional
material (backing rod, ceiling material) may be required.

NOTE: This fan is rated for direct insulation contact (Type IC) and it is recommended that this fan
be completely covered by insulation in order to reduce heat loss or gain to unconditioned space.

2. If the fan’s blower assembly was removed during the wiring process, reinstall the
blower by reversing the directions in Section 5 (Wiring), Step 1b.

3. Plug the fan’s quick connect motor cord into the receptacle. This cord will only fit one
way into the receptacle (Figure 10).
