BASO K16BA-36 Thermocouple

The BASO K16BA-36 Thermocouple is a professional-grade flame sensing component engineered for high-performance standing pilot ignition systems. As a veteran-preferred 36-inch thermocouple, this unit generates a reliable 25–35 mV open-circuit millivolt range, ensuring the gas valve remains energized only when a stable pilot flame is present. Designed as the direct BASO K16BA-36 replacement for legacy K16BA-36C and K16BA-36H models, it provides the necessary heat-to-electrical energy conversion required for safe appliance operation. This thermocouple features a robust copper lead and a specialized tip construction that resists oxidation in high-temperature environments. It is fully compatible with BASO thermo-electric valves and pilot burners, and serves as an interchangeable service part for various OEM configurations, including 17D, 50, 58D, 87D, 88D, 97D, 107D, and K15DA series.

Key Benefits for Contractors

• Direct OEM Compatibility: Serves as a precise standing pilot thermocouple replacement for BASO K16 series and numerous competitive models, reducing truck stock requirements.
• Optimized Millivolt Output: The 25–35 mV range provides a strong signal to the magnet head, preventing nuisance drop-outs and ensuring consistent valve hold-in.
• Extended 36-Inch Reach: The durable 36" lead offers maximum flexibility for routing through complex furnace, boiler, or water heater cabinets to reach the pilot assembly.
• Industrial Build Quality: Constructed by BASO Gas Products with high-grade alloys to withstand thermal cycling and maintain flame sensing accuracy over long-term operation.

Common Questions

What is the proper millivolt reading for a BASO K16BA-36?
In an open-circuit test, this thermocouple should produce between 25 and 35 mV. Under load (closed-circuit), a reading above 10-12 mV is typically required for reliable valve operation.

Can this replace a shorter thermocouple?
Yes, as long as the 36-inch length can be safely coiled without kinking the copper lead. However, you should never replace a longer lead with a shorter one if it creates tension on the connections.

Does this work with electronic ignition systems?
No, the K16BA-36 is specifically designed for standing pilot systems. Electronic or intermittent pilot systems typically require a flame sensor or a different pilot generator (thermopile).
