Auburn E5-FRS-4-4 Flame Rod

The Auburn E5-FRS-4-4 is a professional-grade 4-inch flame rod engineered for precision sensing in demanding HVACR environments. Designed for high-temperature durability, this flame sensor features a robust Kanthal electrode capable of withstanding operating temperatures up to 2350°F, ensuring reliable flame rectification across industrial burners, commercial boilers, and residential furnaces. With its standardized 1/4" NPT mounting (1/4-18 NPT thread) and a 5/8" hex size, the E5-FRS-4-4 provides a secure, leak-proof seal for combustion monitoring. This OEM-quality flame rod is a direct replacement electrode for common models including the Crown CA432 and Eclipse 13093-6. By detecting microamp signals through the ionisation process, it serves as a critical safety component to prevent hazardous gas buildup. Its 5.97-inch overall length and 4-inch probe are optimized for precise placement within the burner's flame path, maintaining system uptime and operational efficiency in complex heating equipment.

• High-Temperature Resistance: Constructed with Kanthal to endure extreme heat up to 2350°F without degrading.
• Precise Flame Detection: Ensures accurate flame rectification to prevent modern control boards from "short cycling."
• Universal 1/4" NPT Fit: Features standard 1/4" mounting threads for easy integration into various burner manifolds.
• Industrial Strength: Manufactured by Auburn (Federal Mogul) in the USA for superior mechanical and electrical reliability.

How do I know if my Auburn flame rod needs cleaning or replacement?
If your system ignites but shuts down after a few seconds, the rod may be coated in carbon soot or oxidation. While light cleaning with a non-abrasive pad can restore connectivity, any signs of a cracked ceramic insulator or a heavily pitted electrode require immediate replacement to ensure safe operation.

What is the typical microamp reading for this sensor?
When functioning correctly within the flame path, the Auburn E5-FRS-4-4 typically generates a DC signal between 1 and 6 microamps. Readings below 1 microamp often indicate a dirty rod, poor grounding, or improper positioning.

Can this rod be used in commercial kitchens or water heaters?
Yes, the E5-FRS-4-4 is highly versatile and frequently used in commercial cooking equipment, industrial ovens, and high-recovery water heaters that utilize 1/4" NPT flame sensing ports.
