Reznor 61146 Pilot Assembly

The Reznor 61146 Pilot Assembly is a high-performance LP gas pilot engineered specifically for technical compatibility with heavy-duty Reznor unit heaters. Designed as an OEM replacement part, this horizontal spark pilot assembly ensures precise propane ignition and stable flame rectification in industrial and commercial heating applications. This liquid propane pilot provides the robust construction required for reliable pilot-to-main burner transition, minimizing lockout errors caused by carbon buildup or sensor fatigue.

For contractors servicing Reznor XL heaters or EEDU and HEEDU series units (sizes 125 to 400), this pilot burner assembly offers a direct-fit solution that maintains factory-specified millivolt signals and spark gaps. Whether you are troubleshooting inconsistent furnace ignition or performing core maintenance on a Reznor unit heater, utilizing this genuine propane gas pilot assembly is essential for optimizing the combustion cycle and preventing hazardous unburned fuel accumulation. This technical component is built to withstand high-cycle environments, ensuring your equipment operates within its original efficiency parameters.

• Compatible with Reznor model XL, XLB, CXL, and CXLB heaters as well as EEDU and HEEDU series.
• Supports horizontal spark ignition setups specifically calibrated for LP gas (Propane) fuel types.
• Factory-aligned electrode and pilot hood configuration ensures immediate propane ignition and flame stability.
• Reduces furnace ignition failures and technician callbacks by restoring OEM-level precision to the burner tray.

Is this pilot assembly compatible with natural gas systems?
No, the Reznor 61146 is specifically orificed and designed for liquid propane (LP gas). Using this in a natural gas application will lead to improper combustion and potential safety hazards.

What are the signs that a Reznor pilot burner assembly needs replacement?
Common indicators include persistent clicking without ignition, "flame not sensed" lockout codes on the control board, or visible corrosion on the spark pilot electrode that prevents a clean arc.

Can I use this for Reznor UDAP or UDX models?
This part is typically used with older XL and EEDU series units. Modern UDAP units utilize different ignition module components; always verify your specific model and serial number before installation.
