Product Description
The Braemar Gas Heater Electrode Flame Sensor Kit (Part No. 638669) is an essential component for Braemar gas heaters, designed to detect the presence of a flame within the combustion chamber. This ensures safe and efficient operation of the heater by providing critical feedback to the control system. If the flame is lost or the sensor is malfunctioning, the gas flow to the burner will be interrupted, preventing potential safety hazards.
Key Features and Functions of the Braemar Gas Heater Electrode Flame Sensor Kit (Part No. 638669):
-
Flame Detection:
- The flame sensor is responsible for detecting the flame within the burner assembly of the Braemar gas heater. It provides important feedback to the control system, confirming whether the flame is present or not.
-
Safety Feature:
- If the flame sensor detects the absence of a flame, the gas flow to the burner will be cut off, preventing the release of unburned gas, which could create dangerous conditions. This makes the flame sensor a critical safety component of the heater.
-
Kit Includes Necessary Components:
- The electrode flame sensor kit (PN 638669) typically includes the flame sensor itself along with necessary installation accessories, such as leads, connectors, and possibly mounting hardware. These components ensure easy replacement and proper installation of the sensor.
-
Compatibility:
- This kit is specifically designed for Braemar gas heaters, ensuring compatibility with the relevant models. The parts within the kit are designed to fit perfectly and restore the proper flame sensing functionality of your heater.
-
Durability:
- The flame sensor is built to endure the high-temperature environment inside the gas heater. It is made from durable materials to withstand frequent heating and cooling cycles over time.
Symptoms of a Faulty Flame Sensor:
-
Failure to Ignite:
- If the flame sensor is faulty, the heater may fail to ignite or may attempt to ignite multiple times without success. The sensor will not detect the flame, and the system will not allow gas to flow to the burner.
-
Frequent Flame Loss:
- A faulty flame sensor may cause the heater to turn off or lose the flame intermittently. The sensor might falsely signal that the flame is out, even when the flame is actually present, causing the heater to shut down.
-
Error Codes:
- Many Braemar heaters feature diagnostic systems that display error codes when a problem occurs with the flame sensor. These codes typically indicate issues such as flame loss or ignition failure.
-
No Gas Flow:
- A malfunctioning flame sensor can prevent the gas valve from opening, meaning the gas will not flow to the burner. This results in the heater failing to operate.
-
Intermittent Heating:
- A heater may start and run briefly before shutting down again if the flame sensor is not functioning properly. This can result in poor performance and inconsistent heating.
How to Replace the Braemar Gas Heater Electrode Flame Sensor Kit (Part No. 638669):
-
Turn Off Power and Gas Supply:
- Ensure both the gas supply and the power to the heater are turned off before beginning any work to prevent accidents or gas leaks.
-
Access the Flame Sensor:
- Open the access panel of the Braemar gas heater to gain access to the burner assembly and flame sensor. You may need to remove other parts to access the sensor.
-
Disconnect the Old Flame Sensor:
- Disconnect the lead or wiring from the old flame sensor. Take note of the wiring connections to ensure proper installation of the new sensor.
-
Remove the Old Flame Sensor:
- Remove the old flame sensor from its position within the burner assembly. This might require loosening screws or clips that secure it.
-
Install the New Flame Sensor:
- Position the new flame sensor from the kit in the same spot as the old one. Secure it with the appropriate screws or clips. Ensure it is properly aligned and securely mounted.
-
Reconnect the Lead:
- Connect the electrical lead from the new flame sensor to the heater’s control system or ignition board, following the original wiring setup.
-
Reassemble the Heater:
- After installing the new flame sensor, reassemble any parts you had to remove to access the sensor.
-
Turn On the Heater and Test:
- Restore power and gas supply to the heater. Turn the heater on and verify that it ignites properly, maintains the flame, and operates safely.
-
Monitor for Error Codes:
- If your heater displays any error codes after replacing the sensor, consult the Braemar user manual to troubleshoot the issue.
Maintenance Tips for the Braemar Gas Heater Flame Sensor:
-
Clean Regularly:
- Over time, carbon deposits can build up on the flame sensor, causing it to malfunction. Clean the sensor periodically to ensure it operates correctly. Use a soft cloth or fine abrasive pad to gently remove any carbon buildup.
-
Inspect for Wear and Damage:
- Periodically check the flame sensor for signs of wear or corrosion. If the sensor appears damaged or worn out, it should be replaced immediately.
-
Check Connections:
- Inspect the electrical connections to the flame sensor. Ensure that the wires are securely connected and free of corrosion to avoid issues with flame detection.
-
Monitor Flame Quality:
- A steady blue flame indicates proper burner operation. If you notice a yellow or flickering flame, it may indicate a problem with the burner or the flame sensor.
-
Error Code Troubleshooting:
- If your heater displays any error codes related to the flame sensor, refer to the Braemar user manual for troubleshooting steps. These codes can guide you to specific issues with the flame sensor or related components.
Conclusion:
The Braemar Gas Heater Electrode Flame Sensor Kit (Part No. 638669) is a crucial part of the Braemar heating system, ensuring safe and efficient operation by detecting the presence of a flame and cutting off gas flow if the flame is lost. If you're experiencing ignition failures, flame loss, or error codes, replacing the flame sensor with the correct part can restore proper function.
By following the installation steps and maintaining the sensor regularly, you can ensure your Braemar gas heater operates safely and efficiently throughout its lifespan.
