Frequently Asked Questions - Ultra Pro RB80 BROAN

How do I install the Broan RB80 fan in new construction?

For new construction, install the mounting frame between joists, snap in the housing and secure it. Attach the muffler, flange, transition, and ducting. Connect 120VAC wiring using the knockout plate. Use the provided mask during ceiling finishing, then install the grille. Refer to the manual for detailed steps.

What duct size is recommended for this fan?

A 4-inch round metal duct is recommended for best performance. Other duct materials may be used but can reduce airflow.

Can the Broan RB80 be installed over a bathtub or shower?

Yes, but it must be marked as suitable and connected to a GFCI-protected branch circuit. Always follow local electrical codes.

How do I clean the fan?

Turn off power at the service panel. Remove the grille and vacuum the interior with a dusting brush attachment. The motor is permanently lubricated and never needs oiling.

What should I check if the fan doesn't run?

Check for a tripped circuit breaker or blown fuse at the service panel. Ensure the motor plug-in connection is secure, and the blower wheel spins freely.

Can I use any speed control with this fan?

Only use the Broan 78V or 78W speed control. Other controls may cause a motor humming noise or damage.

What is the warranty period for the Broan RB80?

Broan provides a 3-year limited warranty from the original purchase date, covering defects in materials or workmanship. It does not cover accessories or damage from improper installation.

Can this fan be installed in a kitchen?

No. The manual states NOT FOR USE IN A COOKING AREA. This fan is designed for general ventilation only and should not be installed above or inside a cooking area.

What replacement parts are available for the RB80?

Replacement parts include the grille assembly, mounting frame, housing, blower assembly, transition, muffler, and wiring panel. Contact Broan for ordering.

How do I troubleshoot a noisy fan?

Check that the back draft dampers in the transition and wall/roof cap pivot freely. Also ensure the blower wheel is firmly attached to the motor shaft and spins freely.

Typical Installation

• Installation is the same for:

Joists

I-Joists

Trusses

• Fits in 2" x 8" ceiling construction.
• Infinitely adjust the fan position between joists from 14" to 24" on center.

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, straighest 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.

WARRANTY PERIOD: Broan warrants to the original consumer purchaser of its Broan Ventilation Fans (the "Fan") that your Fan will be materially free from defects in materials or workmanship for a period of three (3) years from the date of original purchase. This warranty does not cover accessories, such as speed controls, that may be purchased separately and installed with the Fan. The limited warranty period for replacement parts, and for Fans repaired or replaced under this limited warranty, shall continue for the remainder of the original warranty period.

NO OTHER WARRANTIES: THE FOREGOING WARRANTIES ARE EXCLUSIVE AND IN LIEU OF ANY OTHER WARRANTIES, EXPRESS OR IMPLIED. BROAN DISCLAIMS AND EXCLUDES ALL OTHER EXPRESS WARRANTIES, AND DISCLAIMS AND EXCLUDES ALL WARRANTIES IMPLIED BY LAW, INCLUDING WITHOUT LIMITATION THOSE OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. TO THE EXTENT THAT APPLICABLE LAW PROHIBITS THE EXCLUSION OF IMPLIED WARRANTIES, THE DURATION OF ANY APPLICABLE IMPLIED WARRANTY IS LIMITED TO THE PERIOD SPECIFIED FOR THE EXPRESS WARRANTY. Some states do not allow limitations on how long a implied warranty lasts, so the above limitation may not apply to you. Any oral or written description of the Fan is for the sole purpose of identifying it and shall not be construed as an express warranty.

REMEDY: During the applicable limited warranty period, Broan will, at its option, provide replacement parts for, or repair or replace, without charge, any Fan or part thereof, to the extent Broan finds it to be covered by and in breach of this limited warranty. Broan will ship the repaired or replaced Fan or replacement parts to you at no charge.

Incidental damages include but are not limited to such damages as loss of time and loss of use. Consequential damages include but are not limited to the cost of repairing or replacing other property which was damaged if the Fan does not work properly.

Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you. This warranty gives you specific legal rights, and you may also have other rights, which vary from state to state.

This warranty supersedes all prior warranties and is not transferable from the original consumer purchaser.

BROAN SHALL NOT BE LIABLE TO YOU, OR TO ANYONE CLAIMING UNDER YOU, FOR ANY OTHER OBLIGATIONS OR LIABILITIES, INCLUDING, BUT NOT LIMITED TO, OBLIGATIONS OR LIABILITIES ARISING OUT OF BREACH OF CONTRACT OR WARRANTY.
