4. Safety Information
Please observe the following safety precautions to prevent injury or damage:
- Always disconnect power to the fireplace unit before attempting any installation, maintenance, or repair.
- Installation should be performed by a qualified technician or a person with adequate electrical and mechanical knowledge.
- Ensure all wiring connections are secure and comply with local electrical codes.
- Keep hands, hair, and loose clothing away from moving parts during operation.
- Do not operate the blower if it is damaged or if any parts are missing.
- This blower is designed for indoor fireplace use only.
- The motor is UL Approved, indicating compliance with safety standards.
5. Installation
Follow these general steps for installing your fireplace blower kit. Specific installation procedures may vary depending on your fireplace model. Refer to your fireplace's instruction manual for detailed guidance on blower placement.
- Prepare the Fireplace: Ensure the fireplace is completely cool and disconnect its power supply at the circuit breaker.
- Locate Blower Compartment: Identify the designated blower compartment within your fireplace. This is typically located at the bottom or rear of the firebox.
- Verify Dimensions: Before proceeding, confirm that the blower kit's dimensions are suitable for your fireplace's blower compartment. Refer to the images below for critical measurements.
- Position the Blower: Carefully place the blower kit into the designated compartment. Ensure it is stable and positioned to draw in cool air and expel warm air effectively.
- Secure the Blower: If mounting brackets are present on the blower or in the fireplace, secure the blower using appropriate fasteners.
- Connect Wiring: Connect the blower's 3-pin power connector to the fireplace's electrical receptacle for the blower. Ensure connections are firm.
- Test Operation: Restore power to the fireplace. Turn on the fireplace and then activate the blower (if it has a separate switch or thermostat control). Verify that the blower operates smoothly and quietly.

6. Operating Instructions
Once installed, the DN118 Fireplace Blower Kit operates to circulate air and improve heat distribution.
- Activation: Depending on your fireplace model, the blower may activate automatically via a thermostat when the fireplace reaches a certain temperature, or it may have a manual on/off switch.
- Airflow: The blower is designed to move 80 CFM of air, providing a noticeable increase in warm air circulation.
- Noise Level: Expect a low hum during operation. If you notice unusually loud noises, refer to the troubleshooting section.
- Continuous Operation: The blower can operate continuously while the fireplace is in use to maintain consistent heat distribution.
7. Maintenance
Regular maintenance ensures optimal performance and longevity of your blower kit.
- Power Disconnection: Always disconnect power to the fireplace and blower before performing any maintenance.
- Cleaning Frequency: Inspect and clean the blower at least once per heating season, or more frequently if your fireplace is used often.
- Dust and Debris Removal: Use a soft brush or a vacuum cleaner with a brush attachment to gently remove dust, lint, and debris from the fan blades, motor housing, and air intake/exhaust vents.
- Avoid Liquids: Do not use water or liquid cleaners directly on the blower components.
- Lubrication: The motor is typically sealed and does not require lubrication. Do not attempt to lubricate the motor unless specifically instructed by the manufacturer.
8. Troubleshooting
If you encounter issues with your DN118 Fireplace Blower Kit, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Blower does not turn on. | No power, loose wiring, faulty switch/thermostat, motor failure. | Check power supply and circuit breaker. Verify all wiring connections. Test switch/thermostat. If issues persist, contact a qualified technician. |
| Blower is unusually noisy. | Debris in fan, loose mounting, worn bearings. | Disconnect power and inspect fan for debris. Ensure blower is securely mounted. If noise continues, motor may need replacement. |
| Low or no airflow. | Blocked intake/exhaust, fan blades obstructed, motor running slowly. | Disconnect power and clear any obstructions from vents or fan blades. Ensure blower is operating at full speed. |
| Blower runs constantly. | Faulty thermostat or control module. | Consult your fireplace manual or a qualified technician to inspect and replace the thermostat or control module. |
For problems not listed or if solutions do not resolve the issue, contact a qualified service technician.
