This is a single-stage, multi-speed ECM gas furnace with an 80% AFUE rating. The GD9S80 model is a downflow, multi-position unit. It is designed, engineered and assembled in the United States.
The primary heat exchanger is a dual-diameter tubular design made of heavy-duty aluminized steel. Wrinkle-bend technology keeps the wall strength of the tubes and helps transfer heat efficiently. The heat exchanger is wrapped in foil-faced insulation.
The furnace has a single-stage gas valve, a hot-surface igniter and a single-speed draft inducer. A self-diagnostic control board and color-coded low-voltage terminals are included. The cabinet is heavy-gauge steel with a baked-enamel finish. Gas and electrical connections can be made on the left or right.
