90 PLUS®WITH DUAL
COMFORT CONTROL
TWO-STAGE UPFLOW
GAS FURNACES
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 that
traditionally call for a horizontal furnace.
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 two-stage thermostat 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 connec-
tions on upflow models.
■ 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.
■ Pre-paint galvanized steel cabinet.
■ 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.
■ Transformer and control fuse protection.
■ Solid bottom is standard.
■ 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.
