Frequently Asked Questions - A80C BROAN

What are the recommended dimensions for the ceiling opening when installing the Broan A80C fan?

For retrofit installation, the ceiling opening should be enlarged to 9¼ inches parallel to joist and 10½ inches perpendicular to joist.

Can the Broan A80C be installed in a shower or bathtub area?

Yes, but only if connected to a GFCI-protected circuit and installed in the ceiling (not wall).

Does the motor require periodic oiling?

No, the motor is permanently lubricated and never needs oiling. If the motor bearings become noisy, replace the entire blower assembly.

What duct size is required for this fan?

This fan requires a 4-inch round duct to vent to the outside. Use the shortest, straightest routing for best performance.

How do I clean the fan?

Remove the grille and vacuum the interior of the unit using a dusting brush attachment. Do not use water or solvents.

Can the fan be used in a kitchen?

No, this fan is not for use in a cooking area. It is designed for general ventilation only, not for exhausting hazardous or explosive materials.

What is the power supply requirement?

The fan operates on standard 120 VAC, 60 Hz household wiring. It must be grounded.

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. Acceptable for use over a tub or shower when connected to a GFCI (Ground Fault Circuit Interrupter) - protected branch circuit (ceiling installation only).
8. This unit must be grounded.

CAUTION

1. For general ventilating use only. Do not use to exhaust hazardous or explosive materials and vapors.
2. This product can be installed in a wall if mounted 8-ft. or more above the floor.

ALL INSTALLATIONS Start here.

IMPORTANT - 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.

OPTION - To mount housing anywhere between ceiling framing: Use optional Hanger Bar Kit (sold separately from local distributors or website). Follow mounting instructions included with kit.
