The PS80 gas furnaces have an AFUE rating of 80 percent. This line of furnaces features models that can be installed in upflow, downflow, horizontal left, or horizontal right configurations, with no need for accessory conversion kits. For horizontal installations, the rotatable inducer motor allows venting through the top or sides. For downflow installations, these furnaces have a downflow vent guard kit to protect against exposed hot surfaces of vent pipe exiting the side of the furnace. Features include RPJÂ® III heat exchanger, easy on/off doors, built-in SmartValve II systems with diagnostics, and connections for an electronic air cleaner and humidifier. The furnaces are covered by a five-year parts limited warranty and a 20-year limited warranty on the heat exchanger.
