Burnham Boiler 81660154 Gas Valve

The Burnham Boiler 81660154 gas valve is a critical replacement component engineered for specific high-efficiency and standard-efficiency Burnham hydronic heating systems. This 3/4-inch NPT gas valve operates on a 24V AC ignition circuit and is factory-configured for natural gas (NG) applications only. Designed for precision fuel regulation, the valve provides reliable pilot safety and main burner control, ensuring stable manifold pressure across varying load demands. Technicians frequently utilize this Burnham 81660154 replacement valve to resolve intermittent ignition failures or faulty solenoid coils in the field. Its robust construction resists mechanical wear, maintaining tight shut-off capabilities required for residential and light commercial safety standards. When performing a swap, ensure compatibility with the existing control module and verify that the natural gas 24V boiler valve matches the orifice sizing of the manifold to maintain proper BTU output and combustion efficiency.

• Precise Fuel Regulation: Maintains consistent manifold pressure to prevent short-cycling and ensures efficient combustion.
• Standard 3/4" NPT Threading: Facilitates a direct mechanical fit without the need for additional piping adapters in most Burnham configurations.
• Low-Voltage Reliability: Optimized for 24V control transformers, providing stable solenoid engagement even during minor voltage fluctuations.
• OEM-Spec Compatibility: Eliminates the guesswork associated with universal valves, ensuring the flow rate and pilot ports align with the original boiler design.

Is the Burnham 81660154 compatible with Liquid Propane (LP) systems?
No, this specific model is designed for Natural Gas only. Converting this valve for LP use is not recommended as it is factory-calibrated for NG pressure ranges.

What are the symptoms of a failing 24V gas valve?
Common indicators include a pilot that will not light, failure of the main burner to engage despite a signal from the control board, or inconsistent manifold pressure leading to "rumbling" during combustion.

Does this valve include the pilot tubing compression fitting?
Standard replacement units usually require reusing your existing pilot lines, though the ports are standard for Burnham boiler components.
