TWO-STAGE UPFLOW
GAS FURNACES
All Models 95% A.F.U.E. or Above
The Rheem Classic®Series 90 Plus with Dual Comfort Control™line
of upflow gas furnaces are designed for utility rooms, closets, alcoves,
or attics. Because of the low-profile 34 inch [864 mm] height, the
upflow model can also be used to satisfy most applications.
The design is certified by CSA.
Features
■ Two stages of operation to save energy and maintain optimal com-
fort level.
■ Furnace operates at 70% capacity for low-heat and 100% capacity
for high-heat.
■ Compatible with single or two-stage thermostat. (For optimal perfor-
mance a two-stage thermostat is recommended.)
■ 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 handle and
leaves room for optional accessories.
■ Left or right side gas, electric, and condensate drainage connections.
■ Integrated control board manages all operational functions and pro-
vides 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.
■ Features a Limited Lifetime Warranty on the primary and secondary
heat exchanger and a 10-Year Limited Warranty on all other parts.
■ Molded permanent filters.
■ Optional indoor or outdoor combustion air. In addition, combustion
air may be piped to either the top or side of the cabinet on all upflow
models. A special molded fitting is provided to ease installation.
■ Dual certified for sealed combustion (2-pipe) or non-direct (1-pipe)
applications.
■ Solid bottom is standard.
■ Control board diagnostics.
A variety of cooling coils and plenums designed to use with the Rheem
Classic
®
Series 90 Plus 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.

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.
