Super Quiet Door

To help improve the sound quality of the Rheem Classic Series Super Quiet 80, we re-engineered the door to provide a sound
barrier between the furnace's operation and your home.

Heat Exchanger

Awarded three patents, the Rheem Classic Series Super Quiet 80 heat exchanger is renowned for its dependability and
efficiency. It's constructed of aluminized and stainless steel for maximum resistance to rust and corrosion. And it's backed by a
20-year limited warranty.

Induced Draft Motor

When the integrated furnace control receives a call for heat, it activates the draft inducer motor. This draft inducer, which was
specially designed for the Super Quiet 80 gas furnace, quietly provides air for combustion while simultaneously venting outdoors
the products of combustion from the furnace heat exchanger.

Gas Valve

With the call for ignition, the integrated furnace control then opens the gas valve. The redundant gas valve is a 24 volt slow-
opening valve that delivers gas in a regulated flow to the in-shot burners.

In-Shot Burners

The natural (or optional LP) gas is ignited by the direct spark ignition at the in-shot burners. The in-shot burner's shutter free
design requires no adjustments to regulate the air/gas mixture.

Direct Spark Ignition

Direct spark ignition is an extremely dependable and efficient way to light the burner. And it eliminates the need for a standing
pilot. For added safety, the remote flame sensor constantly monitors the burner flame to ensure it is operating as it should.

Adjustable Air Speed

Thanks to adjustable controls for the blower, your technician can precisely match airflow to the specific comfort requirements of
your home.

Integrated Furnace Control

The "Brain" of the Rheem Classic Super Quiet 80 is the Integrated Furnace Control (IFC) which directs all activities of major
furnace components.
