Operating Instructions
The Broan-NuTone 665RP unit offers flexible operation for its heater, fan, and light functions. These functions can be activated independently or simultaneously, depending on your needs and the type of wall switch installed.

- Heater Operation: Turn on the 1300-watt heater for supplemental warmth. Allow a few minutes for the heater to reach its full operating temperature.
- Light Operation: Switch on the light for illumination. The unit accommodates a 100-watt incandescent bulb (not included).
- Combined Use: For maximum comfort and air quality, the heater, fan, and light can be used together. For example, use the fan and heater during a shower to manage humidity and provide warmth.
Note: Multi-function wall switches are required to control each function separately and are sold separately. Consult the instructions provided with your chosen wall switch for specific operation details.
