GAS FURNACES
The Rheem Classic®Series 95% A.F.U.E. 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.
■ Variable speed blower motor technology provides ultimate humidity
control, quieter sound levels and year-round energy savings.
■ 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.
■ Solid bottom is standard.
■ Control board diagnostics.
A variety of cooling coils and plenums designed to use with the Rheem
Classic
®
Series 95% A.F.U.E. 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.
“Proper sizing and installation of equipment is critical to achieve optimal performance. Split system air conditioners and heat pumps must be
matched with appropriate coil components to meet ENERGY STAR criteria. Ask your Contractor for details or visit www.energystar.gov.”
