RHEEM CLASSIC 90 Plus Furnace

The Rheem Classic 90 Plus series consists of single and two-stage gas furnaces offering up to 95 percent AFUE. All models are designed for easy installation and have a low, 34-inch profile for upflow, horizontal and downflow configurations. While all models in this series are promoted for their quiet operation with a soft-operating PCS motor, an insulated blower compartment, and a slow-open gas value, only the two-stage units have a multi-stage function. This feature contributes to improved furnace efficiency by allowing the system to consistently operate on a lower stage until the need for increased heat is detected. Additional features of the Classic 90 Plus series include an aluminized steel heat exchanger, direct spark ignition and remote sensor, and a pre-painted galvanized steel cabinet designed for durability and protection.
