• 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
RGFG- model can be used vertically to satisfy most
 applications that traditionally call for a horizontal furnace.
The design is certified by CSA.

nostic codes and fault history codes by detecting system and
electrical problems. “Call for Service” alert notification is sent
to the thermostat to alert the homeowner of required service.

 Com muni cat ing Condensing Unit and user interface control
 (RHC-TST550CMMS) 500 Series thermostat this unit offers 4
or 2 wire installation, auto-configuration, and diagnostic mes-
saging with full communicating capability.

municating  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 thermo-

stat, furnace functions as a three stage furnace operating at
40%, 65% and 100% of total capacity.

• Primary heat exchanger is constructed of all aluminized steel

for maximum corrosion resistance and thermal fatigue reliability.

• Reduced firing rates, electrically efficient ECM 3.0 motor, and

solid doors provide the ultimate in quiet operation.

• Low speed constant fan.
