3. Installation work and electrical wiring must be done by a qualified person(s) in accordance with all applicable codes and standards, including fire-rated construction codes and standards.
4. Sufficient air is needed for proper combustion and exhausting of gases through the flue (chimney) of fuel burning equipment to prevent backdrafting. 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.
5. When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities.
6. Ducted fans must always be vented to the outdoors.
7. Never place a switch where it can be reached from a tub or shower.
8. A dimmer switch may be used to operate the light in this unit. Refer to the list of compatible dimmer switches on broan.com.
9. Install this unit in a flat ceiling only.
10. For use in non fire rated installations only.
11. Not for use in environmental air handling spaces.
12. 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.
13. Do not install in a ceiling thermally insulated to a value greater than R60.
14. This unit must be grounded.

CAUTION

1. For general ventilating use only. Do not use to exhaust hazardous or explosive materials and vapors.
2. To avoid motor bearing damage and noisy and/or unbalanced impellers, use the cardboard protector (provided) to keep drywall spray, construction dust, etc. off power unit.
3. Please read specification label on product for further information and requirements.

OPERATION

The fan and light can be operated using various combinations of on/off switches and controls:

• Fan and light controlled with single on/off switch
• Fan and light controlled with separate on/off switches
• Fan controlled with timer control
- Selectable fan CFM - 50 or 80

See "Connect Wiring" section for various wiring options.

Typical Installation

The unit can be installed anywhere between ceiling joists using mounting brackets provided.

* Install in a flat ceiling only.

INSULATION* (Place around and over Fan Housing.) FAN HOUSING POWER CABLE* Seal gaps around Housing. 4-IN. ROUND DUCT* *Purchase separately. Insulation* (Place around and over Fan Housing.) ROOF CAP* (with built-in damper) Keep duct runs short. BR 4-IN. ROUND ELBOWS* WALL CAP* (with built-in damper)

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.

Plan to supply the unit with proper line voltage and appropriate power cable.

COOKING AREA Do not install above or inside this area 45° 45° Cooking Equipment Floor

Do not install in a cooking area.

The unit must not be installed above or inside the cooking area shown.

INSTALLATION

CARDBOARD PROTECTOR

1. Install mounting brackets.

Slide the adjustable mounting brackets into the bracket channels on the housing.

Bend the tabs on the cardboard protector and insert protector into opening in housing.

NOTE: The cardboard protector shields the inside of the housing from drywall spray and construction dust. Do not remove it until after construction is completed.

1/8" GAP

2. Mark mounting location.

Position unit between joists and extend mounting brackets. IMPORTANT: Position brackets so there will be an 1/8" gap between bottom of housing and ceiling material. Mark the top of keyhole slot on all four mounting brackets.

4. Hang and secure housing.

Hang unit from nails. Check to make sure that there will be a 1/8" gap between bottom of housing and ceiling material. Pound nails tight. For wide joist centers: A #8 x 3/8 self-tapping screw can be used to join extended brackets together and create a rigid mount. To ensure a noise-free mount, crimp the bracket channels tightly around mounting brackets.

FLUSH ① FAN SIDE ② ② ①

5. Attach damper/duct connector.

Snap the damper/duct connector onto housing. Make sure that tabs on the connector lock in housing slots. (Top of damper/duct connector will be flush with top of housing.) Install ductwork.

NOTE: Make sure damper flap is in place inside of duct connector. If it is not: ① Squeeze top and bottom of connector to ② snap flap back into place.

HORIZONTAL POWER CABLE CONNECTION VERTICAL POWER CABLE CONNECTION

6. Choose power cable direction.

Remove wiring plate. When re-attached, the wiring plate allows the power cable to enter unit horizontally or vertically.

7. Connect wiring.
