BASO K16FA-36 Thermocouple

The BASO K16FA-36 Thermocouple is a professional-grade flame sensing component engineered for high-reliability in standing pilot ignition systems. This universal-style thermocouple is a direct replacement for various gas-fired applications, including commercial boilers, residential furnaces, and water heaters. It features a 36-inch lead length and a specific 3.546-inch junction lead, providing the necessary reach and secure fit for diverse burner configurations. Technical performance is centered on its open circuit voltage range of 25–35 mV, ensuring the gas valve electromagnetic coil remains energized only when a stable pilot flame is detected. For technicians performing field service, the K16FA-36 is a drop-in identical replacement for the K16FA-36H, offering the same millivolt output and thermal response times required for safety shutoff protocols.

Key Technical Benefits:

• Universal Compatibility: Optimized for standing pilot ignition systems across residential and commercial gas appliances.
• High-Output Performance: Delivers a consistent 25–35 mV open circuit range to ensure reliable flame detection and valve operation.
• Precision Engineering: Includes a 3.546" junction lead and 36-inch thermocouple lead for versatile installation in tight burner assemblies.
• Durable Construction: Built to withstand high-temperature environments, reducing nuisance call-backs due to premature sensor failure.

Common Questions:

Is the K16FA-36 compatible with millivolt gas valves?
Yes, this thermocouple is designed to generate the standard 25–35 mV required to hold in the safety magnet of most standing pilot gas valves.

Can I use the K16FA-36 to replace a K16FA-36H?
Absolutely. The K16FA-36 and K16FA-36H are identical in specifications, lead length, and millivolt output, making them fully interchangeable.

What causes a thermocouple to fail in a standing pilot system?
Common failure points include soot buildup on the tip, improper flame impingement, or internal resistance increases. If your pilot won't stay lit despite a clean orifice, the 25–35 mV output of the BASO K16FA-36 provides the reliable millivoltage needed for proper system reset.
