GAS FURNACES
The Rheem®Classic®90 Plus®High Efficiency line of downflow/horizontal gas furnaces are designed for utility rooms,
closets, alcoves, attics or crawl spaces. The RGTA is
shipped in the downflow configuration and is easily converted for horizontal left-hand airflow applications.
The design is certified by CSA.
Features
■ Heat exchanger is constructed of all stainless steel for
maximum corrosion resistance and thermal fatigue
reliability.
■ Low profile “34 inch” design is lighter and easier to han-
dle and leaves room for optional accessories.
■ Top electrical connections, left or right gas and conden-
sate drainage connections on downflow models.
■ Condensate drain for horizontal application provided
standard.
■ Integrated control board manages all operational func-
tions and provides hookups for humidifier and electronic
air cleaner.
■ An insulated blower compartment, a slow-opening gas
valve and a specially designed inducer system make it
one of the quietest furnaces on the market today.
■ Pre-paint galvanized steel cabinet.
■ Molded permanent filters.
■ Optional indoor or outdoor combustion air.
■ Transformer and control fuse protection.
■ Control board diagnostics.
A variety of cooling coils and plenums designed to use with
the Classic 90 Plus gas furnaces are available as optional
accessories for air conditioning models.
✝A.F.U.E. (Annual Fuel Utilization Efficiency) calculated in accordance with Department
of Energy test procedures.

FOR HIGH ALTITUDES
*HIGH ALTITUDE KIT: RXGY-F04-105 KBTU/H
RXGY-F06-45/60/90 KBTU/H
RXGY-F05-120 KBTU/H
RXGY-F07-75 KBTU/H
*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. 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.
