The Rheem

Prestige Series

™ 90 Plus High Efficiency line of upflow gas fur-

naces 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.

Features

■ The

Comfort Control2System

™ provides 28 on-board diagnostic 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.

■

Serial Communication Enhanced – When installed with a Serial 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 messaging with full communicating capability.

■ Heat exchanger is constructed of all stainless steel for maximum corro­sion resistance and thermal fatigue reliability.

■ Modulating Function: when used with a modulating or communicating
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 ECM 3.0 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.

■ Hot surface ignition with remote sense.

■ Optional indoor or outdoor combustion air.

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

Prestige

Series

™ 90 Plus gas furnaces are available as optional accessories.

alerts the homeowner to any
necessary service require­ments. Faster, more accurate
service is provided by the built­in diagnostics, by providing the HVAC professional with depend­able information.

■

The fault recall feature will allow for the last six fault-codes
to be displayed, and will retain these codes even if power
failure occurs.

FOR HIGH ALTITUDES:

Installations up to 5,000 ft. do not require a special kit or option.
However, an orifice change may be required based on heating value
and elevation. See Installation Instructions for more information.

Installations above 5,000 ft. are not permitted.
CAUTION: Always follow National Fuel Gas Code (NFGC) guidelines

when converting furnaces for high altitudes.
For all installations above 2000 ft. 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.

[ ] Designates Metric Conversions

Before proceeding with installation, refer
to installation instructions packaged
with each model, as well as complying
with all Federal, State, Provincial, and
Local codes, regulations, and practices.
