Description
The Lennox 83W12 is a 24-volt, two-stage gas valve engineered for reliable fuel delivery and precise flow control in compatible Lennox heating systems. Designed to support two-stage furnace operation, this valve allows the system to run at a lower first-stage capacity for mild heating demands and ramp up to full second-stage output when greater heat is required — improving comfort, efficiency, and temperature consistency throughout the conditioned space.
