Electrical Rating

120V / 1Ph / 60Hz / less than 12A

1. Listed Input and Output ratings are at minimum vent lengths at an altitude of 0-2000 ft. Numbers will be lower with longer venting and/or altitudes greater then 2000 ft. 2. Ratings based on standard test procedures prescribed by the U.S. Department of Energy; certified by AHRI. Efficiency listed for models TFTN340 and TFTN399 represents Thermal Efficiency (AFUE is not applicable). 3. TFTN units require a special venting system, use only vent materials and methods detailed in the installation manual.
