BURNHAM NEW YORKER 8236024 Thermocouple

The Burnham New Yorker 8236024 Thermocouple is a heavy-duty, 30-inch pilot safety component designed for high-reliability millivolt systems. This part is a direct cross-reference for the Honeywell Q309A1988 and is engineered to deliver consistent DC voltage to the gas valve solenoid upon flame impingement. Built to withstand high combustion chamber temperatures, the 8236024 thermocouple features a robust universal pilot burner interface with a standard 11/32"–32 UNS nut connection. In the field, this lead is essential for ensuring the pilot safety circuit remains closed, preventing gas flow in the event of flame failure. Whether you are servicing a residential hydronic boiler or a light commercial steam system, the 30-inch lead length provides ample slack for proper routing away from high-heat zones, reducing the risk of premature junction failure. This OEM replacement part ensures precise millivolt output and compatibility with a wide range of standing pilot gas valves.

• Universal Compatibility: Directly replaces Honeywell Q309A1988 and various Burnham New Yorker OEM leads.
• Optimized Conductivity: High-purity copper lead construction minimizes resistance for stable pilot flame sensing.
• Thermal Durability: Stainless steel tip construction resists oxidation and maintains probe integrity under constant pilot heat.
• Simplified Installation: Standard push-in clip and threaded nut design allows for rapid swapping during service calls.

Is the 8236024 compatible with non-Honeywell gas valves?
Yes, as long as the valve utilizes a standard 11/32" thermocouple port, this 30-inch lead will interface correctly with most millivolt gas control blocks.

What is the typical millivolt range for this thermocouple?
Under an open-circuit load, you should expect 25 to 30 mV. Under a normal closed-circuit load, it should maintain 10 to 15 mV for reliable valve operation.

Why use a 30-inch lead instead of a shorter 18-inch version?
The extended length allows for safer wire management and prevents sharp bends that can damage the internal coaxial insulation, extending the service life of the pilot assembly.
