DOWNFLOW/
HORIZONTAL
GAS FURNACES
The Rheem Value Series 90 High Efficiency line of downflow/horizontal gas furnaces are designed for utility rooms,
closets, alcoves, attics or crawl spaces. The RGTS is
shipped in the downflow configuration and is easily converted for horizontal 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 Rheem Value Series 90 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.

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
