Classic Series: 80% Gas Furnace
The Rheem Classic® Series Gas Furnace was developed using our 360°+1 design philosophy, which means every detail of the product is meticulously evaluated from every angle. We consider the work that goes into installing and servicing our products, as well as how we can deliver the very best homeowner experience. And then we take it a step further. That’s 360°+1. And that’s why you can count on your gas furnace to bring you and your family years of comfort.
We Did the Work So You Can Stay Comfortable
Our gas furnace line was already recognized as best in its class**, but that didn’t stop us from making it better. We designed our new Classic® Series Gas Furnace to provide your home with reliable, quiet comfort for years to come.
Reliability is essential to your home comfort. That’s why we’ve engineered our gas furnace with the 1 PlusOne™ Ignition System. Our Direct Spark Ignition is a Rheem-exclusive feature that’s nine times more reliable than most hot surface igniters. It’s also the same proven design used in commercial HVAC equipment and gas home appliances. Our patented head exchanger is quick and easy to clean – when needed – by your local independent Rheem Dealer. And a clean furnace is a long-running furnace.
Quiet operation is the result of a 2 tighter door seal that helps eliminate whistling. We’ve also added 3 rubber grommets on the motor mounts and a 4 twist-lock wire harness in the blower shelf. The result is an impressively quiet furnace.
Fast and accurate diagnostics are a big benefit to both you and your dealer. The Rheem Classic® Series Gas Furnace features 5 PlusOne™ Diagnostics, our industry first 7-segment alphanumeric LED display that simplifies troubleshooting. Just in case there’s a need, service calls are faster, which ultimately saves you money.
Save on your energy bill with a new gas furnace from Rheem. Our R801S delivers 80% AFUE, which means 80% of the fuel in your furnace is converted to heat for more efficient comfort and savings for your home. Hassle-free installation saves you and your dealer time and trouble. The 6 34″ cabinet fits nicely in tight spaces allowing for both new construction and retrofit installations.
