Burnham Boiler 109620-01 Valve

The Burnham Boiler 109620-01 Valve is a critical gas control component engineered for precise natural gas manifold pressure regulation between 0.7" and 3.5" W.C. This 1/2-inch NPT gas valve features a step-opening characteristic, ensuring smooth ignition transitions and stable combustion across Burnham residential hydronic systems. As a direct OEM replacement valve for discontinued part numbers 81660145U and 81660282, it maintains the structural integrity and safety parameters originally specified by the manufacturer. Designed for high-duty cycle applications, this valve utilizes standard 24V AC wiring terminals for seamless integration with existing boiler control boards and pilot generators. For service technicians, this unit provides a reliable solution for correcting boiler ignition delay or inconsistent burner pressure in aging systems. Ensure gas valve manifold adjustment is performed with a calibrated manometer during installation to match the appliance data plate specifications.

Key Benefits

• Direct Replacement Compatibility: Specifically engineered to replace 81660145U and 81660282 without manifold modifications.
• Step-Opening Performance: Facilitates controlled initial gas flow for soft ignition and reduced mechanical stress on the heat exchanger.
• Precise Pressure Regulation: High-sensitivity internal diaphragm maintains a consistent 0.7-3.5" W.C. output for optimal AFUE ratings.
• Compact 1/2" Footprint: Standard NPT threading ensures a secure, leak-free connection in tight boiler cabinets.

Common Questions

Is this valve compatible with Propane (LP) systems?
No, this specific model is calibrated for Natural Gas (N/G). Converting this valve for LP use requires a manufacturer-certified conversion kit to ensure safe pressure regulation.

What are the symptoms of a failing 109620-01 gas valve?
Common indicators include hard starts, intermittent boiler lockout codes, or a complete failure of the main burners to ignite despite a confirmed pilot flame or spark.

Can I use this to replace other 1/2" gas valves?
This is an OEM Burnham part. While the threading is standard, electrical ratings and opening speeds are specific to Burnham sequences. Always verify cross-reference compatibility before installation.
