®
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.
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.

FOR HIGH ALTITUDES:
*For installations over 5000 ft.
OPTION CODE FOR HIGH ALTITUDE: US & Canada – 278
NOTE: High altitude kits and options do NOT include additional
burner orifices. If a burner orifice change is necessary, they
must be ordered through PROSTOCK
®
. See Installation
Instructions for more information.
Option – 278 furnaces are shipped with #51 DMS orifices installed.
This is one drill size smaller than standard furnaces to account for
expected average elevations and heating values typically seen in
these areas.
CAUTION: Always follow National Fuel Gas Code (NFGC) guidelines
when converting furnaces for high altitudes.
For all installations above 2000 ft. (including all option – 278
models), the burner orifice size needs to be recalculated and
verified at elevations above 2000 ft. A burner orifice change may
still be required. See Installation Instructions for more
information.
Manifold gas pressure reduction methods to adjust for altitude may
NOT be used on these models. The only method permitted on
modulating furnace models is to recalculate the burner orifice size.
See Installation Instructions for more information.
