Models with Input Rates

(All Models 90% A.F.U.E.† or Above)
The Rheem Value Series 90 High Efficiency line of upflow
gas furnaces are designed for utility rooms, closets, or
alcoves. Because of the low-profile 34 inch height, the
90RJ model can be used vertically to satisfy most applications that traditionally call for a horizontal furnace.
The design is certified by the CSA.
Features
■ Low profile “34 inch” design is lighter and easier to handle
and leaves room for optional accessories.
■ Left or right side gas, electric, and condensate drainage
connections.
■ Integrated control board manages all operational func-
tions and provides accessory 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.
■ Textured galvanized steel cabinet with painted access
doors.
■ Optional indoor or outdoor combustion air. In addition,
combustion air may be piped to either the top or right side
of the cabinet on all upflow models. A special molded fitting is provided to ease installation.
■ 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: 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 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.
