Lennox 10A85 Gas Valve
The Lennox 10A85 is a high-performance two-stage natural gas valve designed for precision fuel regulation in residential and light commercial heating systems. This Honeywell VR8305Q4500 derivative features a 1/2-inch NPT inlet and outlet, facilitating a standard footprint for quick field replacements. Engineered for two-stage gas furnaces, it utilizes a 24V redundant solenoid configuration to ensure reliable ignition sequences and stable manifold pressure across both low and high-fire cycles. For technicians troubleshooting Lennox furnace gas valves, this unit offers consistent millivolt output stability and integrated pressure taps for accurate manometer readings during commissioning. Its robust construction resists thermal fatigue, making it a critical component for maintaining AFUE ratings and ensuring peak combustion efficiency in Lennox G24, G32, and G40 series units.
Key Benefits for Technicians- Direct OEM Replacement: Matches exact factory specifications for Lennox 10A85 and 60M44 models, ensuring zero-clearance issues during installation.
- Advanced Regulation: Precise two-stage gas control optimizes fuel consumption and reduces cycling noise.
- Standard Threading: Features a 1/2" x 1/2" NPT connection for compatibility with common black iron pipe fittings.
- Serviceability: Built-in pressure taps allow for rapid verification of inlet and outlet gas pressure.
Is the Lennox 10A85 compatible with LP conversion kits?
Yes, this dual-stage gas valve can be converted for Liquid Propane applications using the manufacturer-specified LP conversion kit, though the regulator must be adjusted according to the furnace nameplate specifications.
What are the symptoms of a failing two-stage gas valve?
Technicians typically observe delayed ignition, failure to transition from low to high fire, or a total lockout with 24V signal present at the solenoid but no gas flow at the manifold.
Does this valve replace the Honeywell VR8305 series?
The 10A85 is a specific technical variant of the VR8305 gas valve line. Always verify the cross-reference guide to ensure the electrical terminals and stage logic match the existing control board.
