Airco KHM-100 Multi-Position Highboy Front Flue Oil-Fired Furnace

The Airco KHM‑100 is a durable multi‑position highboy oil-fired furnace engineered for reliable residential heating in a wide range of installation layouts. Its adaptable cabinet design supports upflow, horizontal, or downflow configurations, making this oil-fired furnace suitable for basements, utility rooms, closets, and retrofit applications where duct orientation varies. The front‑flue layout provides straightforward venting in traditional oil‑heat systems, while the heavy‑gauge steel heat exchanger delivers consistent heat transfer and long service life under demanding operating conditions.

A factory‑installed oil burner ensures clean, stable combustion and dependable ignition performance. The insulated cabinet reduces operating noise and improves thermal efficiency, and the front‑access design simplifies installation and routine service. Designed to integrate with a wide range of duct systems, the KHM‑100 provides strong airflow performance in a compact, flexible footprint—ideal for homeowners and installers who need a furnace that adapts to the space rather than the other way around.
