Burnham Boiler 81660143 Gas Valve

The Burnham Boiler 81660143 Gas Valve is an OEM 1/2" 24V Natural Gas Valve manufactured by Honeywell (model VR8200C3005) specifically for Burnham IN3-IN6 series boilers. As a critical combustion component, this standing pilot gas valve regulates fuel flow to maintain precise manifold pressure. It serves as the direct replacement for VR8200C6008, providing a seamless retrofit for technicians servicing legacy atmospheric boiler systems. Designed for standard capacity applications, this natural gas control valve features a compact swing radius and a 24V redundant solenoid for automated operation. Integrating this Burnham replacement part ensures the system adheres to original factory specifications for gas-to-air ratios and safety shut-off protocols. Whether you are addressing a failed solenoid or a leaking diaphragm, this HVAC gas valve provides the reliability required for high-demand residential heating environments.

Key Benefits for Contractors

• Direct OEM Compatibility: Engineered as the exact factory substitute for the Burnham 81660143 and Honeywell VR8200C6008, eliminating field fabrication.
• Standardized Connections: Features 1/2" NPT inlet and outlet ports with a 1/4" compression fitting for pilot tubing.
• Optimized Regulation: Factory-set for natural gas at 3.5" W.C. to ensure stable flame characteristics in Burnham IN series heat exchangers.
• Redundant Safety: Dual-seated valve design provides an extra layer of protection by ensuring gas shut-off if one seat fails.

Common Questions

Is this valve compatible with LP (Propane) systems?
No, this specific model is configured for natural gas. While some VR8200 series valves can be converted, you must use the manufacturer-approved LP conversion kit or the correct LP-specific part number to ensure safe manifold pressure.

Can I use this to replace a VR8200C6008?
Yes, the 81660143 (VR8200C3005) is the official Burnham Boiler replacement for the discontinued VR8200C6008.

What is the torque specification for the 1/2" NPT pipe connections?
Standard NPT installation practices apply. Use high-quality pipe dope or gas-rated PTFE tape, ensuring you do not over-torque the valve body, which can lead to hairline fractures or internal component misalignment.
