311AAV - Plus 80™ Description
The 311AAV Deluxe 4-Way Multipoise Gas Furnace offers outstanding features in an 80% AFUE furnace. Deluxe features include: third fan relay for discrete continuous fan speed, the ability to change continuous fan speeds from the thermostat, dehumidify mode, optional Media Filter Cabinet, fault code storage, and more. The Plus 80™ is very quiet thanks to a new combustion design that eliminates noise, instead of just muffling or boxing it in. Applications are easy with 4-way multipoise design, through-the-furnace downflow venting, 13 different venting options, and a door designed for easy service access. An inner blower door is provided for tighter sealing in sensitive applications. The 311AAV furnace is approved for use with natural or propane gas.
