LEGACY™ 80 ULTRA LOW NOx GAS FURNACE The 830SB 4-way Multipoise Gas Furnaces offer features not found in other single-stage 80% gas furnaces. Improved serviceability with the 3 digit status display and NFC enabled board allowing setup via the service tech app. These models meet the nitrogen oxides (NOx) emission limit of 14 nanograms/joule for the South Coast Air Quality Management District and San Joaquin Valley Air Pollution Control District in California. The gas furnace control system provides fault code storage in the event of power outages. Applications are easy with 4-way multipoise design, 6 different venting options, and a design for easy service access.
