Bradford White 233-42013-01 Assembly

The Bradford White 233-42013-01 Natural Gas Pilot Assembly is a direct OEM replacement component engineered for precision ignition in Bradford White water heaters. This assembly features a robust thermopile and thermocouple configuration designed to maintain a consistent millivolt signal to the gas control valve, ensuring reliable burner ignition and flame sensing. Designed specifically for natural gas water heater repair, the assembly includes the pilot orifice, electrode, and high-temperature lead wires necessary for a complete pilot light assembly replacement. It integrates seamlessly with the Defender Safety System (FVIR) to prevent accidental combustion of flammable vapors outside the unit. For technicians, this genuine Bradford White part ensures factory-spec tolerances for gas flow and mounting alignment, reducing call-backs caused by pilot outages or weak millivolt output. Replace the entire assembly when the pilot fails to stay lit or the thermopile output falls below 400mV under load to restore domestic hot water system performance.

• OEM Compatibility: Exact fit for Bradford White pilot assembly 233-42013-01, eliminating field modifications.
• Enhanced Flame Sensing: High-grade thermocouple materials ensure stable millivolt generation for consistent gas valve operation.
• HVACR Professional Grade: Built to withstand high-combustion chamber temperatures without premature oxidation of lead wires.
• Simplified Installation: Includes pre-assembled mounting bracket for rapid integration with the existing burner manifold.

How do I know if the pilot assembly or the gas valve is faulty?
Test the thermopile millivolt output with a multimeter while the pilot is lit; if it reads below the required threshold (typically 400-750mV) despite a clean flame, the assembly requires replacement.

Does this assembly include the pilot orifice?
Yes, this natural gas pilot assembly comes with the calibrated orifice pre-installed to ensure the correct fuel-to-air ratio for Bradford White burners.

Is this part compatible with Liquid Propane (LP) units?
No, this specific part number is engineered strictly for natural gas water heaters. Using natural gas orifices in LP applications creates a significant safety hazard.
