The Rheem Prestige Series™Super Quiet 80™Two Stage line of upflow/
horizontal gas furnaces are designed for utility rooms, closets, alcoves, or
attics. Because of the furnace’s low-profile 34 inch [864 mm] height, the
upflow model installed vertically can also be used to satisfy most
applications that traditionally call for a horizontal furnace.
The design is certified by CSA International.
Features
■
The Comfort Control2System™ provides over 28 on-board diagnostics
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 Communicating 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.
■
Patented Heat Exchanger, constructed of both stainless and aluminized
steel for the maximum in corrosion resistance.
■
Low profile “34 inch” [864 mm] design is lighter and easier to handle, and
leaves room for optional equipment.
■
Energy efficient and quiet ECM 2+ communicating motor.
■
Improves cooling efficiency when matched with rated condensing unit
and coil.
■
Constant CFM.
■
Seven segment LED for system diagnostics.
■
Diagnostic history for troubleshooting.
■
Dip switch settings for selectable cooling airflow.
■
On-demand dehumidification terminal for improved comfort in cooling mode.
■
Convertible from upflow to horizontal left or right.
■
Left or right side gas and electric inlet connections.
■
All models equipped with flame sensor feature, an integrated board with
humidifier and electronic air cleaner hookups.
■
Insulated blower compartment, a slow-open gas valve, a specially
designed draft inducer motor and blower motor make it one of the quietest
furnaces on the market today.
■
Pre-paint galvanized steel cabinet.
■
Molded permanent filter.
■
Easy door removal and replacement.
■
Compatible with single or two-stage thermostat. (For optimal performance,

. See Installation instructions for more
information.
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. A burner orifice change may still be
required. See Installation Instructions for more information.
NOTE: For Canadian installations only, an optional derate (manifold
gas pressure reduction) method may be used to adjust the
furnace for altitude. See Installation Instructions for more
information. This optional method may NOT be used for U.S.
installations.
