HIGH EFFICIENCY
DOWNFLOW/
HORIZONTAL
GAS FURNACES

The Rheem®Classic®90 Plus®High Efficiency line of down­flow/horizontal gas furnaces are designed for utility rooms,
closets, alcoves, attics or crawl spaces. The RGTA is
shipped in the downflow configuration and is easily con­verted for horizontal left-hand airflow applications.

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.

■ Top electrical connections, left or right gas and conden-

sate drainage connections on downflow models.

■ Condensate drain for horizontal application provided

standard.

■ 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.

■ Transformer and control fuse protection.

■ 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.
