Crown Engineering CA436 Flame Rod
The Crown Engineering CA436 Flame Rod is a critical industrial combustion component designed for high-sensitivity flame rectification in commercial boilers and furnaces. As a heavy-duty direct replacement for the Auburn FRS-4-12 and Maxon 18291, this unit features a 12-inch rod length and a rugged 1/4-inch NPT mounting for secure installation in high-heat environments. Engineered to withstand the thermal stresses of industrial burner cycles, the CA436 ensures consistent signal strength back to your primary flame safeguard controller, preventing nuisance shutdowns and maintaining combustion system safety. Technical specifications confirm a total length of approximately 14 inches with a 0.16 lb weight, making it a lightweight yet durable sensor for diverse HVACR equipment. Whether you are performing routine maintenance or a full burner overhaul, the Crown Engineering CA436 provides the reliable ionizing flame detection required for modern high-efficiency operations.
Key Benefits
- Direct Cross-Reference: Seamlessly replaces Auburn FRS-4-12, US Ignition R6003, and Eclipse 13093-1 without mechanical modification.
- Precise Flame Detection: Optimized for accurate flame sensing, ensuring your burner management system recognizes a stable flame instantly.
- Industrial-Grade Build: Constructed with materials designed to resist oxidation and carbon buildup in harsh thermal zones.
- Standard Mounting: Features a 1/4" NPT threaded connection, facilitating quick field replacement and reduced technician downtime.
Common Questions
- Is this rod compatible with my existing igniter? The CA436 is designed as a standalone flame rod for rectification systems; verify your control module utilizes a microamp signal for flame verification.
- Can I trim the 12-inch rod to fit a smaller burner? While physical modification of the flame sensor is possible, it is recommended to use the factory 12-inch length to maintain the specified ion collection area for consistent signal.
- Does this include the insulator? Yes, the assembly includes the porcelain insulator and terminal connection as part of the complete Crown CA436 kit.
