90 PLUS 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.
Features
■Heat exchanger is constructed of all stainless steel for maximum corrosion resistance and thermal fatigue reliability.
■Modulating Function: when used with a modulating thermostat, modulation rate between 40% and 100% of total capacity.
■Two-stage Function: when used with a two-stage thermostat, furnace operates at 40% on first stage, and stages up to 65%, then 100% for second stage.
■Multistage Function: when used with a single-stage thermostat, furnace functions as a three stage furnace operating at 40%, 65% and 100% of total capacity.
■Reduced firing rates, electrically efficient ECM2+ motor, and solid doors provide the ultimate in quiet operation.
■Low speed constant fan.
■Constant temperature rise for superior comfort.
■Seven segment LED for system diagnostics.
■Diagnostic history for troubleshooting.
■Two-speed induced draft motor.
■Direct spark ignition with remote sense.
■Top electrical connections, left or right gas and condensate drainage connections on downflow models.
■Optional indoor or outdoor combustion air.
■All models comply with Department of Energy test procedures for 2% or less electrical efficiency ratings.
A variety of cooling coils and plenums designed to use with the Prestige Series™ 90 Plus gas furnaces are available as optional accessories.
A.F.U.E. (Annual Fuel Utilization Efficiency) calculated in accordance with Department of Energy test procedures.
