3. Safety Information
- Always disconnect power to the fireplace before installation or maintenance.
- Ensure proper grounding to prevent electrical hazards. If the kit does not provide a dedicated ground wire connection to the fireplace frame, it is recommended to add one for safety.
- Do not operate the blower if any wires are damaged or exposed.
- Keep hands and foreign objects away from moving parts of the fan.
- Consult a qualified technician if you are unsure about any part of the installation or operation.
4. Installation Guide
The FBK-100 kit is designed for straightforward installation. The kit comes largely pre-wired, simplifying the connection process.
4.1 Pre-Installation Steps
- Safety First: Turn off all power to your fireplace unit at the circuit breaker.
- Access Fireplace Interior: Remove the access plate or bottom vent of your fireplace to expose the interior space where the blower will be installed.
- Inspect Area: Ensure there is adequate space for the blower unit (refer to dimensions in Section 2.3). Clear any debris.
4.2 Blower Installation
- Position the Blower: Carefully slide the blower unit into the designated space within the fireplace. The galvanized mounting bracket should align with existing mounting points or allow for secure placement.
- Apply Noise Reduction Pads: Attach the included double-stick foam pads to the blower unit where it contacts the fireplace walls. These pads help reduce noise and vibration transmission.

4.3 Electrical Connections
The kit is largely pre-wired. You will primarily need to connect the blower to the control components and power source.
- Connect Blower Wires: Connect the two female connectors from the wiring harness to the corresponding terminals on the blower motor.
- Ground Wire Connection: Securely attach the green ground wire to the metal frame of the blower unit using a screw. Ensure good metal-to-metal contact. If the fireplace frame itself is not grounded through the kit, it is recommended to add an additional ground wire from the blower frame to the fireplace frame for enhanced safety.
- Connect Thermostat and Speed Control: Connect the wires from the magnetic thermostat switch and the variable speed control to the main wiring harness as indicated in the included diagram.
- Power Connection: Plug the 3-prong power cord into a suitable electrical outlet within the fireplace compartment.

4.4 Post-Installation
Once all connections are secure, replace the access plate or bottom vent. Restore power to the fireplace.
5. Operating Instructions
5.1 Automatic Operation
The FBK-100 features a magnetic thermostat switch. When the temperature inside the fireplace reaches approximately 120°F (50°C), the blower will automatically activate to circulate warm air. It will turn off once the temperature drops below this threshold.
5.2 Adjustable Fan Speed
The kit includes a variable speed control knob. You can adjust this knob to set the desired airflow and noise level. Turn the knob clockwise to increase fan speed and counter-clockwise to decrease it.

6. Maintenance
Regular maintenance ensures optimal performance and longevity of your blower fan.
- Cleaning: Periodically inspect the blower unit for dust and debris accumulation. Disconnect power and use a soft brush or vacuum cleaner to gently clean the fan blades and motor housing.
- Inspection: Check all electrical connections for tightness and signs of wear. Ensure the noise reduction pads are still securely in place.
- Motor: The sealed ball bearing motor is designed for long-term, maintenance-free operation. No lubrication is required.
