Notes:
•These charts are for furnaces installed at 0 - 2000 feet. At higher altitudes, a properly derated unit will have the same temperature rise at a particular CFM, while the ESP at that CFM will be lower.
•The installation must be adjusted to obtain a temperature rise within the range listed on the furnace nameplate.
•Do not operate above .5” w.c. ESP in heating mode.
•Propane gas installations will have a High Stage rise approximately 4° lower than shown in above table.
