MODULATING UPFLOW GAS FURNACES
WITH CONTOUR COMFORT CONTROL®
The Rheem Prestige Series® 90 Plus High Efficiency line of upflow gas furnaces are designed for utility rooms, closets, or alcoves. Because of the low-profile 34 inch height, the
RGFDmodel can be used vertically to satisfy most applications that traditionally call for a horizontal furnace.
The design is certified by CSA.
