Reznor 97534 Pilot Assembly

The Reznor 97534 Pilot Assembly is a high-performance natural gas pilot burner and flame sensor kit engineered for industrial and commercial heating equipment. Built around the Baso Q90FF-1 specification, this assembly is a critical HVAC replacement part for Reznor unit heaters and duct furnaces requiring precise ignition. It features a robust 18-inch sensor lead cable and a .032" pilot orifice to ensure consistent flame detection and furnace ignition reliability. Field technicians often rely on this OEM Reznor pilot for its universal compatibility across Series 6 units and various gas-fired appliances. This kit includes the necessary pilot tubing, flame rod, and fitting to restore safe operations and prevent common gas heater pilot failures. Designed to withstand high-temperature combustion environments, the assembly provides accurate real-time data to the gas valve, minimizing downtime caused by dirty or restricted sensors.

• Universal Compatibility: Specifically designed for Reznor Series 6 unit heaters and applications requiring the Q90FF-1 pilot group.
• Complete Ignition Kit: Includes the flame sensor, 18-inch lead wire, pilot burner, and tubing for a streamlined installation.
• Precision Orifice: Features a .032" orifice optimized for stable natural gas combustion and reliable flame rectification.
• Durable Construction: High-grade materials designed for the high-thermal stress of industrial HVACR duty cycles.

Why is my Reznor heater failing to light?
Failure to ignite is often caused by a restricted pilot orifice or carbon buildup on the flame rod. If cleaning the assembly does not restore a steady blue flame, a full Reznor 97534 Pilot Assembly replacement is the standard procedure to ensure safety.

Is the compression nut included with this assembly?
This kit includes the standard pilot tubing and fitting; however, some installations may require a separate 1/8" pilot male compression nut (part number 97572) depending on the specific gas valve configuration.

Can this pilot assembly be used for propane (LP) units?
The standard 97534 is calibrated for natural gas systems. For propane applications, a different orifice size is typically required to maintain the correct fuel-to-air ratio and flame intensity.
