GAS FURNACES
The Rheem 90 Plus High Efficiency line of upflow gas furnaces are designed for utility rooms, closets or alcoves.
The design is certified by CSA.
Features
■ 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 han-
dle and leaves room for optional accessories.
■ Left or right side gas, electric, and condensate drainage
connections on upflow models.
■ Integrated control board manages all operational func-
tions and provides 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.
