Patterson-Kelley 86-2450-0820 Electrode Kanthal
The Patterson-Kelley 86-2450-0820 Electrode is a critical combustion component engineered for high-output commercial boiler ignition systems. Constructed from Kanthal steel, this ignition electrode is specifically designed to handle the extreme thermal cycling and oxidation prevalent in industrial HVACR equipment. As a lead-acid or spark-governing element, it provides the precise high-voltage arc required to initiate the fuel-air mixture safely and consistently. This OEM replacement part ensures your burner assembly maintains tight spark gap specifications, typically 1/8-inch for natural gas applications, preventing delayed ignition or nuisance "no flame" lockouts on Modu-Fire or Thermific series units. The steel electrode housing is built to resist carbon fouling and corrosive flue gases, sustaining electrical conductivity over extended run hours. Field-proven in technical environments, this flame sensor electrode is the standard for maintaining peak combustion efficiency and reliable secondary flame detection. Proper positioning is vital; ensure the electrode is flush with the pilot tube and the clamp is secure to prevent ceramic cracking during high-vibration operation.
Key Benefits:
- High-Temperature Durability: Engineered with Kanthal steel to withstand industrial furnace temperatures without warping or oxidizing.
- Precise Ignition Performance: Delivers a consistent high-voltage spark to eliminate delayed ignition pulses and burner "whooshing."
- OEM Compatibility: Exact-fit replacement for Patterson-Kelley 86-2450-0820, ensuring zero-modification installs in commercial boilers.
- Corrosion Resistance: Protective material properties resist sulfur and moisture buildup common in condensing and non-condensing heat exchangers.
- Enhanced System Reliability: Minimizes "All Limit Points Alarm" (ALPA) triggers by providing stable combustion system starts.
Common Questions:
What is the recommended spark gap for this electrode?
For standard Patterson-Kelley natural gas applications, the spark gap between the 86-2450-0820 electrode and the ground rod should be maintained at 1/8-inch (+1/16”, -0”).
How do I prevent the ceramic insulator from cracking during installation?
Technicians should ensure the electrode clamp is snug but not overtightened. Thermal expansion during the firing cycle can cause high-stress fractures if the mounting is too rigid.
Can this electrode be used for both ignition and flame sensing?
Yes, in many Patterson-Kelley burner configurations, this Kanthal steel electrode serves the dual purpose of spark generation and flame rectification (sensing) through the control circuit.
