The Plus 80™ Gas Furnace
The 311AAV/JAV 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, standard
Media Filter Cabinet, fault code storage, and more. The Plus 80 is very
quiet thanks to a new combustion design that eliminates noise, not just
muffle or box 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/JAV furnace is
approved for use with natural or propane gas, and the 311JAV is also
approved for use in Low NOx Air Quality Management Districts.
