The Rheem Prestige Series™90 Plus High Efficiency line of hori­zontal gas furnaces are designed for utility rooms, closets, or alcoves,
attics or crawl spaces.

The design is certified by CSA.

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 (RHC­TST550CMMS) 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 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 ECM2+ motor, and solid
doors provide the ultimate in quiet operation.

■ Low speed constant fan.

■ Constant temperature rise for superior comfort.

■ Dual Seven segment LED for system diagnostics.

■ Diagnostic history for troubleshooting.

■ Two-speed induced draft motor.

■ Direct spark ignition with remote sense.

■ Top electrical connections.

■ Optional indoor or outdoor combustion air.

■ All models comply with Department of Energy test procedures for

2% or less electrical efficiency ratings.

alerts the homeowner to any
necessary service require­ments. Faster, more accurate
service is provided by the
built-in 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.

. 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 must
be recalculated and verified. A burner orifice change may still be
required. See Installation Instructions for more information.

Manifold gas pressure reduction methods 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.
