Lennox P/N 73W17 – Genuine OEM Single-Stage Gas Valve 


The Lennox 73W17 (Catalog 73W17) is a genuine OEM Single-Stage Gas Valve engineered for precise fuel control and safe operation in Lennox, Armstrong, and Allied heating systems. As a critical ignition component, this valve regulates natural gas flow to the burners, ensuring efficient combustion while providing a vital safety shutoff. It is designed for dual direct ignition systems (hot surface or direct spark) and serves as the primary regulator to maintain stable heat output. 

 

Choosing a Genuine Lennox Approved replacement like the Honeywell VR8215S1248/B ensures perfect electrical and mechanical compatibility. Generic valves may not meet the exact pressure response times required by your furnace’s control board, potentially leading to ignition delays or safety lockouts. This OEM valve is factory-calibrated for natural gas but can be converted to LP with the appropriate manufacturer kit. 


Key Features and Function:

  • Precise Fuel Regulation: Factory-set to 3.5" W.C. for optimal natural gas combustion.
  • Genuine OEM Reliability: Trusted Honeywell/Resideo build quality provides quiet operation and long-term durability.
  • Dual Safety Shutoff: Meets rigorous safety codes with a solenoid-operated first valve and a diaphragm-operated second valve.
  • Universal Mounting: Features an "any direction" mounting design for easier installation in tight furnace cabinets.

  • Part Number: 73W17 (replaces 102837-01)

  • Honeywell P/N: VR8215S1248/B
  • Fuel Type: Natural Gas (LP convertible)

🛠️ HVAC Depot Pro Tip: The Soap Bubble Test

After installing the 73W17, never skip the leak test. Apply a non-corrosive bubble solution to the 1/2" NPT inlet and outlet connections while the furnace is running. Even a tiny, slow-growing bubble indicates a leak that must be sealed. Always check manifold pressure with a manometer to ensure it matches the 3.5" W.C. spec on your furnace rating plate for the safest, most efficient flame.
