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.
