™

“The RGRM- 12 gas furnace has earned the ENERGY STAR®in all

U.S. South States.”

✝A.F.U.E. (Annual Fuel Utilization Efficiency) calculated in

accordance with Department of Energy test procedures.

• 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.

• Two stages of operation to save energy and maintain optimal
comfort level.

• Furnace operates at 70% capacity for low-heat and 100%

capacity for high-heat.

• Compatible with single or two-stage thermostat. (For optimal

performance a two-stage thermostat is recommended.)

• Heat exchanger is constructed aluminized 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 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.

• 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.
