Lennox 97N56 – Honeywell SV9502H2522/U SmartValve gas valve is an OEM HVAC replacement designed to deliver precise and reliable gas flow control in gas-fired furnace systems. Engineered with Honeywell SmartValve technology, this valve integrates ignition control and gas regulation into a single, dependable component, helping ensure safe startup, smooth operation, and consistent heating performance.

This gas valve features an intermittent hot surface pilot (HSI) ignition system combined with a slow-opening design. The slow-opening operation reduces ignition noise and minimizes stress on burners and heat exchangers by allowing gas flow to increase gradually. With 1/2" x 1/2" inlet and outlet connections and a regulated 3.2" WC outlet pressure, the Lennox 97N56 is built to meet OEM specifications for compatible Lennox furnaces and HVAC equipment.

Designed for professional HVAC service and repair applications, this SmartValve gas valve helps restore proper ignition sequencing, improve system reliability, and maintain manufacturer-rated performance. Using an OEM Lennox gas valve ensures correct fitment, safe operation, and long-term durability compared to aftermarket alternatives.
