GAS FURNACES
The Rheem Classic Series®90 Plus with Dual Comfort Control line of
downflow/horizontal gas furnaces are designed for utility rooms, clos-
ets, alcoves, or attics. T
he RGTK is shipped in the downflow configuration and is easily converted for horizontal left-hand airflow
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 per-
formance two-stage thermostat recommended.)
■ Heat exchanger tubular construction is 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.
■ Top electrical connections, left or right side gas, and condensate
drainage connections on downflow/horizontal models.
■ 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.
■ Pre-paint galvanized steel cabinet.
■ Molded permanent filters.
■ Optional indoor or outdoor combustion air.
■ Transformer and control fuse protection.
■ Control board diagnostics.
■ Condensate drain trap for horizontal/downflow application provided
standard.
A variety of cooling coils and plenums designed to use with the
