Auburn Ignition Products E5-FRS-2-18 Flame Rod 18in 1/2in Npt

Product Description

The AUBURN IGNITION PRODUCTS E5-FRS-2-18 is an 18-inch flame rod designed for flame sensing in gas-fired combustion systems. Flame rods are a critical safety component: they pass a small electrical current through the burner flame to prove ignition and allow the gas valve to remain open. Without a confirmed flame signal, the control board shuts down the burner. The E5-FRS-2-18 features an 18-inch rod length and a 1/2-inch NPT fitting for straightforward installation into the combustion chamber or burner assembly. It is a direct-replacement-style component suited to licensed HVAC technicians and combustion equipment service professionals.

Flame rods of this type are commonly installed in commercial and industrial gas-fired burners, boilers, furnaces, and process heating equipment that use a dedicated flame rectification circuit. The 1/2-inch NPT threaded mount allows installation into a wide range of burner bodies and combustion chamber ports where rod-style flame sensing is specified. The 18-inch length accommodates deeper combustion chambers or burner configurations that require extended reach to position the rod tip within the flame envelope.

Key Features

• 18-inch rod length for extended reach into deeper combustion chambers
• 1/2-inch NPT threaded fitting for secure, leak-resistant mounting
• Designed for flame rectification sensing circuits in gas-fired combustion equipment
• Direct-replacement-style construction for service and maintenance applications

Compatibility

Designed as a replacement-style flame rod for gas-fired combustion systems that use rod-style flame sensing with a 1/2-inch NPT mount and require an 18-inch rod length. No specific compatible model numbers were provided in the product data.

Installation Notes

Flame rod replacement is typically performed by a licensed HVAC technician or combustion equipment service professional. Before servicing, shut off gas supply and disconnect electrical power to the appliance in accordance with local codes and the equipment manufacturer's instructions. Ensure the replacement rod is fully threaded into the NPT port and that the electrical lead is connected to the correct terminal on the ignition control module. Do not allow the rod body or lead to contact grounded surfaces, as proper insulation from ground is essential for the flame rectification circuit to function correctly.
