The Ducane 96G1DF045BE12K is a 96% AFUE downflow gas furnace designed for smaller residential heating applications that require efficient performance in a compact footprint. With heating output in the 45,000 BTU/hr range and support for 3‑ton cooling, it fits well in homes where the furnace must integrate with moderate‑capacity air‑conditioning equipment. Its single‑stage heating design provides straightforward, reliable operation, while the ECM blower motor helps maintain consistent airflow and quieter performance. The downflow configuration makes it suitable for installations where ductwork is located below the unit, such as in closets or utility spaces, and its stainless‑steel secondary heat exchanger supports long‑term durability.
