Rheem Classic® R801T- Series Upflow/Horizontal Gas Furnaces Features

Rheem's gas furnace line was already recognized as best in its class**, but that didn’t stop us from making it better. We designed Rheem's new Classic Plus Series Gas Furnace to provide your home with reliable, easy-to-maintain and quiet comfort for years to come.

Reliability is essential to your home comfort. That’s why we’ve engineered Rheem's gas furnace with the PlusOne Ignition System. Rheem's 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. Rheem's patented heat exchanger is quick and easy to clean – when needed – by your local independent Rheem Dealer. And a clean furnace is a long-running furnace.

Increase your energy savings with a new gas furnace from Rheem. Rheem's R801T delivers 80% AFUE, which means 80% of the fuel in your furnace is converted to heat. The constant torque ECM motor maintains efficiency across a range of operating speeds, using less electrical energy than a standard PSC motor.

Fast and accurate diagnostics are a big benefit to both you and your dealer. The Rheem Classic Plus Series Gas Furnace features PlusOne Diagnostics, Rheem's 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.

Hassle-free installation saves you and your dealer time and trouble. The 34" cabinet fits nicely in tight spaces allowing for both new construction and retrofit installations
