With Dual Comfort Control
™
“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.

Option – 278 furnaces are shipped with #51 DMS orifices installed.
This is one drill size smaller than standard furnaces to account for
expected average elevations and heating values typically seen in
these areas.
CAUTION: Always follow National Fuel Gas Code (NFGC) guidelines
when converting for high altitudes.
For all installations above 2000 ft. (including all option – 278 models),
the burner orifice size needs to be recalculated and verified. A burner
orifice change may still be required. See Installation Instructions for
more information.
NOTE: For Canadian installations only, an optional derate (manifold
gas pressure reduction) method may be used to adjust the
furnace for altitude. See Installation Instructions for more
information. This optional method may NOT be used for U.S.
installations.

Requires field installation).
