Burnham Boiler 8236084 Ignition Sensor

The Burnham Boiler 8236084 Ignition Sensor is a critical component for maintaining reliable flame rectification in high-efficiency hydronic heating systems. This 36-inch ignition sensor lead wire is designed specifically for Burnham Alpine and Burnham ES2 series boilers, ensuring consistent communication between the flame sensor electrode and the Honeywell ignition module. Built to withstand the high-temperature environment of the combustion chamber, this direct replacement ignition wire utilizes high-grade insulation to prevent signal loss or electrical interference. When a boiler lockout occurs due to weak flame signals, replacing the flame rod lead is a standard diagnostic step for technicians to restore safe boiler operation. This part ensures the automatic ignition system functions within factory specifications, providing the precision required for modern modulating condensing boilers and standard atmospheric units alike. Proper installation of this 36" lead wire prevents nuisance service calls and ensures the burner recognizes a stable flame during the ignition sequence.

Key Benefits for Field Application:

• OEM Compatibility: Exact fit for Burnham residential boilers, eliminating the need for field-splicing or custom wiring harnesses.
• High-Temperature Durability: Engineered with silicone-insulated wiring to resist heat degradation near the burner assembly.
• Optimal Signal Integrity: Provides the low-resistance path necessary for accurate microamp flame signal transmission to the controller.
• Extended Reach: The 36-inch length offers sufficient slack for clean routing through the boiler jacket and away from moving components.

Common Contractor Questions:

Can I use this sensor wire on other boiler brands?
While it features standard spade or boot connectors, this part is specifically indexed for Burnham 8236084 specifications. Always verify the terminal type and length match your specific flame rectification requirements.

Why is my boiler showing a flame failure code even after cleaning the sensor?
A common failure point is the internal conductor of the lead wire. Over time, heat cycles can cause high resistance or intermittent continuity, making a new ignition sensor lead necessary to resolve 133 or 135 error codes.

Does this include the flame rod electrode?
No, this is the 36-inch ignition sensor lead wire only. If the ceramic insulator on the probe is cracked, you must purchase the electrode assembly separately.
