DOWNFLOW/
HORIZONTAL
GAS FURNACES
The Rheem®Classic®90 High Efficiency line of downflow/
horizontal gas furnaces are designed for utility rooms, clos-
ets, alcoves, attics or crawl spaces. The RGTJ is shipped in
the downflow configuration and is easily converted for hori-
zontal left-hand airflow applications.
The design is certified by CSA.
Features
■Low profile “34 inch” design is lighter and easier to handle
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 functions
and provides hookups for an electronic air cleaner.
■A slow-opening gas valve and a specially designed
inducer system make it one of the quietest furnaces on
the market today.
■Galvanized steel cabinet.
■Optional indoor or outdoor combustion air.
■Control board diagnostics.
A variety of cooling coils and plenums designed to use with
the Classic 90 gas furnaces are available as optional acces-
sories for air conditioning models.
✝A.F.U.E. (Annual Fuel Utilization Efficiency) calculated in accordance with Department
of Energy test procedures.

OPTION CODE FOR HIGH ALTITUDE: U.S. & 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.

Before proceeding with installation, refer
