The Payne PG8MAA is a discontinued gas furnace with an efficiency of 80% AFUE. The PG8MAA featured a four-way multipoise design — upflow, horizontal right, horizontal left, and downflow. It had a four-pass heat exchanger and used a hot surface ignition. A soft-mounted inducer motor reduced vibration noise, while LED diagnostics and a self-test feature monitored furnace operation. The pre-painted cabinet was scratch-resistant for lasting durability.
