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.
A variety of cooling coils and plenums designed to use with
