Product Description
The Braemar WF25 Ignition Unit Fenwal 35-615300-113 for Gas Wall Furnace Heaters (Part Number: 628608) is an essential component in the ignition system of your Braemar WF25 Gas Wall Furnace Heater. It is responsible for safely and reliably igniting the gas supply to the heater, ensuring the system starts and operates correctly.
Key Features of the Braemar WF25 Ignition Unit Fenwal 35-615300-113:
-
Ignition Control:
- The Fenwal 35-615300-113 Ignition Unit is an electronic ignition control module that initiates the spark to ignite the gas and ensure the proper flame sequence for efficient heating. The ignition module manages the sequence of operations, including the ignition timing and flame sensing, ensuring the safe operation of the gas heater.
-
Compatibility:
- This ignition unit is designed specifically for the Braemar WF25 Gas Wall Furnace Heaters. It ensures compatibility and reliable operation within this specific model, but it’s always a good idea to check compatibility with your specific furnace before purchase.
-
Flame Sensing:
- This unit also functions as a flame sensor to detect the presence of a flame once ignition occurs. If the flame is not detected within a certain timeframe, the ignition control unit will shut down the gas flow to prevent unsafe operation, protecting the system from potential hazards.
-
Durability and Reliability:
- The Fenwal Ignition Unit is made of high-quality materials that ensure long-lasting performance, even in high-temperature environments, contributing to the overall durability and reliability of the heater.
-
Voltage and Power Requirements:
- The ignition unit operates on 24V DC power, a standard voltage for most modern heating systems. This ensures that the unit operates efficiently and safely without putting undue strain on the heater’s electrical system.
-
Safety Features:
- The ignition unit is equipped with safety shutdown features that protect the gas system in case of ignition failure. If a flame is not detected, or if the ignition fails to occur within a certain time period, the unit will automatically shut off the gas supply, preventing any risk of gas accumulation.
Installation of the Braemar WF25 Ignition Unit Fenwal 35-615300-113 (PN: 628608):
-
Ensure Safety:
- Before starting the replacement process, turn off the gas and disconnect the power to the heater. This is critical to ensure safety during the installation of the ignition unit.
-
Access the Ignition Unit:
- To access the ignition unit, you will need to remove the front access panel or cover of the heater. Depending on your heater model, the ignition unit is typically located near the gas valve and burner assembly.
-
Remove the Old Ignition Unit:
- Disconnect the wiring from the old ignition unit. Take note of how the wiring is connected so you can replicate the connections with the new unit.
- Carefully remove the old Fenwal ignition unit from its mounting bracket. You may need to unscrew or detach it from the heater’s internal components.
-
Install the New Ignition Unit (628608):
- Position the new Fenwal ignition unit (Part No. 628608) in place and secure it with screws or mounting clips, as needed.
- Reconnect the electrical wiring to the terminals on the new ignition unit. Ensure that all wiring is secure and correctly matched with the old connections.
-
Reconnect the Gas and Power:
- After the ignition unit is installed, reconnect the gas supply and restore power to the heater.
-
Test the Heater:
- Once the ignition unit is installed, turn the heater on and test its functionality. The unit should initiate the ignition sequence, and the flame should ignite correctly. Observe the process to ensure the flame sensing and ignition timing are working properly.
-
Check for Gas Leaks:
- After installing the ignition unit and testing the heater, check for any gas leaks around the gas connections. If you notice any leaks, turn off the gas and tighten the connections before re-testing.
Troubleshooting:
-
Ignition Failure:
- If the ignition unit is not initiating the spark, check the electrical connections to ensure they are secure. Additionally, ensure that the thermocouple or flame sensor is functioning correctly, as a failure here may prevent ignition.
-
Flame Failure:
- If the unit ignites but the flame does not stay on, this may be a sign of a faulty flame sensor or a problem with the gas supply. The ignition unit will shut off the gas if the flame is not detected within the required time.
-
Gas Valve Issues:
- If the ignition unit is working but the heater is not lighting, there may be an issue with the gas valve. Check the valve for proper operation and ensure it is opening and closing as needed.
-
Repeated Lockout:
- If the system enters lockout mode after multiple failed ignition attempts, ensure that the ignition sequence is correct and that all components are in working order. Refer to the user manual or consult a professional technician if needed.
Conclusion:
The Braemar WF25 Ignition Unit Fenwal 35-615300-113 (Part Number 628608) is a critical component that ensures safe and reliable ignition of the Braemar WF25 Gas Wall Furnace Heater. It helps regulate the ignition sequence and flame sensing, providing both safety and efficiency to your heating system. Proper installation and regular maintenance will help extend the lifespan of your heater and ensure it operates at optimal performance.
