3. Setup and Installation
3.1 Tools Required
- Screwdriver (Phillips head, typically)
- Safety glasses (recommended)
- Work gloves (recommended)
3.2 Installation Steps
- Safety First: Before beginning installation, ensure the power to the bath fan circuit is turned off at the circuit breaker.
- Remove Old Grille: Carefully remove the existing grille. Most grilles are held in place by a center screw or spring clips. If a screw is present, unscrew it. If clips, gently pull down to release.
- Clean Fan Housing: While the grille is off, it is an opportune time to clean any dust or debris from the fan housing and motor.
- Position New Grille: Align the Nutone BP24 grille with the fan housing. The grille is designed for center screw mounting.
- Secure Grille: Insert the appropriate screw (not included with grille, typically reused from old grille or supplied with fan unit) through the center hole of the BP24 grille and into the fan housing's mounting point. Tighten the screw until the grille is securely in place, but do not overtighten.
- Restore Power: Once the grille is securely installed, restore power to the bath fan circuit at the breaker.
- Test Operation: Turn on the bath fan to ensure proper operation and that the grille is securely attached and does not rattle.

4. Operating Instructions
The Nutone BP24 grille is a passive component of your bath fan system. Its primary function is to cover the fan housing and direct airflow. Once installed, no specific operational steps are required for the grille itself. The operation of the bath fan (turning it on/off) is controlled by your existing wall switch or fan control.
5. Maintenance
Regular maintenance of the grille helps maintain optimal airflow and appearance.
- Cleaning: Periodically wipe the grille surface with a soft, damp cloth to remove dust and grime. For more stubborn dirt, a mild soap solution can be used. Avoid abrasive cleaners or harsh chemicals, as these may damage the finish.
- Deep Cleaning (Optional): For a more thorough cleaning, the grille can be removed by unscrewing the center screw. Wash it with warm soapy water, rinse thoroughly, and allow it to dry completely before reinstallation.
- Inspection: Annually inspect the grille for any signs of damage or loose connections. Ensure the center screw remains tight.
