1. These charts arefor furnaces installed at 0' - 4,500'. At higher altitudes, a prooperly derated unti will have the same
temperature rise at a particular CFM, while the ESP at the CFM will be lower.
2. The installation must be adjusted to obtain a emperature rise within the range listed on the furnace nameplate.
3. Do not operate above .5" w.c. EXP in heating mode.
4. Propane gas installations iwll have High Stage rise approximately 4° lower than shown in above table.
