Overview

The Ruud Ultra Series 90 Plus High Efficiency upflow gas furnaces are designed for utility rooms, closets or alcoves. Because of the furnace's low profile 34 inch [864 mm] height, the upflow model installed vertically can also be used to satisfy most applications that traditionally call for a horizontal furnace.
