Burnham Boiler 81660278 Gas Valve

The Burnham Boiler 81660278 Gas Valve is a reliable, high-performance solution for residential heating applications, specifically designed for RV3-RV7 boiler models. This 3/4" step-open natural gas valve is an essential component for technicians maintaining intermittent pilot ignition systems. As an OEM replacement part, it ensures precise fuel delivery and stable combustion, meeting rigid safety standards for dual automatic shutoff. The valve operates on a 24V AC heating control circuit and features a 3.5" W.C. pressure regulator set point to maintain optimal manifold pressure across varying supply conditions. This Burnham 81660278 gas control serves as a direct upgrade for aging Honeywell Smart Valve series or legacy SV9602P4816 units. With a straight-through body pattern and standard 3/4" NPT inlet and outlet connections, it simplifies field installation for contractors. Integrating this genuine Burnham boiler part preserves system efficiency and ensures compatibility with existing S8600 series control modules, providing the technical reliability required for critical winter operation.

Common Questions About This Part

Can this valve be converted for Liquid Propane (LP) use?
Yes, while this is a natural gas valve, it can typically be converted using a manufacturer-approved LP conversion kit (often 393691), though original settings are optimized for natural gas.

How do I confirm if my original valve is compatible?
Verify the part number on your existing unit. This valve is the direct replacement for Burnham part 81660278 and legacy numbers like 81660213 or Honeywell SV9602P4816.

What are the electrical requirements for installation?
This is a standard 24V gas valve. Ensure your transformer is rated for at least 40VA to handle the solenoids and ignition module load simultaneously.
