As a member of Lennox's Elite Series of furnaces, the G32 is a discontinued mid-level furnace offering up to 94 percent AFUE. According to information from its introduction in 2001, this model features two-stage heating, meaning it was designed to consistently operate on a lower heating level until the system detects a change in the temperature. Benefits of two-stage heating include even heating throughout the home, reduced energy usage and increased temperature regulation, according to the manufacturer.
Additional components of the G32 include a low speed continuous fan operation setting for increased air circulation, an insulated blower motor compartment designed to reduce operation noise, and a two-stage gas valve that quietly adjusts the levels of gas depending on which stage of heating is operating.
