Lennox 47K24 Gas Valve

The Lennox 47K24 Gas Valve is a direct replacement, standing pilot ignition control designed for high-efficiency gas-fired furnaces and heating systems. Primarily cross-referenced as the Honeywell VR8205H2605, this valve operates on a 24V AC circuit and is factory-calibrated for natural gas with a 3.5" WC manifold pressure setting. Featuring a standard 1/2" NPT inlet and outlet, it ensures seamless integration into existing manifolds without requiring complex piping modifications. This dual-stage gas valve provides precise fuel flow regulation, critical for maintaining combustion efficiency and stable flame signals in commercial and residential HVAC applications. Designed for reliability in high-cycle environments, the 47K24 manages pilot gas flow and main burner synchronization effectively. When replacing this component, technicians must verify WC pressure settings and terminal configurations to ensure full compatibility with the furnace control board and pilot assembly.

• Universal Compatibility: Exact replacement for Lennox 47K24 and Honeywell VR8205H2605 models.
• Precise Regulation: Pre-set to 3.5 inches water column for optimal natural gas combustion.
• Standard Porting: 1/2-inch NPT connections allow for straightforward field installation.
• Reliable Switching: 24-volt solenoid operation ensures responsive opening and closing cycles.

Common Installation Questions

Can this valve be converted to Liquid Propane (LP)?
Yes, while factory-set for natural gas, this valve typically supports conversion using a manufacturer-approved LP conversion kit to adjust the regulator spring for higher manifold pressures.

Does this replace the VR8205H2605 exactly?
Yes, the 47K24 is identical to VR8205H2605 in terms of electrical specs, physical footprint, and BTU capacity, making it a drop-in replacement for Lennox heating units.

What are the electrical requirements for the solenoid?
This unit requires a 24V, 50/60Hz power supply. Always measure voltage at the gas valve terminals during the ignition sequence to troubleshoot furnace lockout issues.
