®

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

RGFD- model 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 ther-

mostat, modulation rate between 40% and 100% of total
capacity.

■ Two-stage Function: when used with a two-stage thermo-

stat, 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 ther-

mostat, 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 conden-

sate drainage connections on downflow models.

■ Optional indoor or outdoor combustion air.

■ All models comply with Department of Energy test proce-

dures for 2% or less electrical efficiency ratings.
