When it comes to value and innovatoin, the Criterion II gas furnace offers you a full range of important features-features based on proven designs and reliable leading edge technology.

THE CRITERION® II
80% Gas Furnace

 

1) Integrated Furnace Control
Rheem's solid-state integrated furnace control board is the "brains" of the Criterion II. Using dependable computer technology, it controls the different components of the furnace-such as the blower and inducer motors-to give you the maximum heating compacity and improved effeciency. The control features low speed continuos fan operation and accessory terminals. The furnace control also carries a five-year limited warranty.

2) Induced Draft Blower
The induced blower was designed to work specifically with Rheem's exclusive heat exchanger. The blower quietly and reliably pulls hot combustion gases through the exchanger and vents them safely outdoors when the furnace is in the heating cycle. The blower is covered by a five-year limited warranty.

3) Ignition Systems
Whether it's a hot surface ignitor or a direct spark, our ignition systems are an extremely effeciently way to ignite gas from the burners when the furnace cylces on. During operation, the remote flame sensor constantly monitors the status of the burner flames.

4) Gas Valve and Manifold
When the integrated furnace control signals the furnace to cycle on, it first waits for the hot surface ignitor to heat up, then it opens the gas valve. This 24-volt, slow-opening valve is a redundant valve that smoothly delivers gas in a regulated flow to the in-shot burners for quiter operation.

5) In-Shot Burners
Rheem's in-shot burners are carefully matched to the heat exchanger. Their shutter-free design requires no adjustments to regulate the air/gas mixture possible, which means heat is transferred into your home more effeciently.

6) Heat Exchanger
The heat exchanger is the heart of the Criterion II Gas Furnace-a revolutionary design so innovative that it carries three patents. It's smaller than virtually any other primary heat exchanger on the market and is constructed of aluminized and stainless steel to resist corrosion and thermal fatigue. It carries a 12-year limited warranty.

8) Easy Access Washable Filter
Regularly changing the air filter on your furnace is important because a dirty filter cuts efficiency of your furnace and strains its components. We've solved this problem by making available a permanent washable filter that is easy to get to and easy to clean.
