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.
