Burnham 8236004 Thermocouple with 36" Lead for Gas Boilers

The Burnham 8236004 is a genuine OEM replacement thermocouple designed specifically for Burnham 806 and 807 series gas boilers. This critical safety component monitors pilot flame temperature and generates the voltage signal necessary to keep the gas valve open during operation.

Key Features:

• 36-inch lead length provides flexible installation options
• 24V thermocouple compatible with standing pilot ignition systems
• Honeywell Q309A1996 thermocouple element for reliable performance
• Genuine Burnham replacement part ensuring proper fit and function
• Monitors flame presence to prevent gas flow when pilot is extinguished

This thermocouple generates a small voltage when heated by the pilot flame, signaling the gas control valve to remain open. If the pilot flame goes out, the thermocouple cools and stops generating voltage, automatically closing the gas valve as a critical safety feature. Regular replacement of this component ensures reliable boiler operation and maintains safe combustion control in your heating system.

Specifications:

• Lead Length: 36 inches
• Voltage Rating: 24V
• Compatible Models: Burnham 806, 807 series boilers
• Replaces: Honeywell Q309A1996
