GAS FURNACES
The Rheem ® Classic ® 90 Plus ® High Efficiency line of down-
flow/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 con-
verted 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.
