Notes:
• CFM in chart is without fi lter(s). Filters do not ship with this furnace, but must be provided by the installer. If the furnace requires two return fi lters, this
chart assumes both fi lters are installed.
• All furnaces ship as high-speed cooling and medium-speed heating. Installer must adjust blower cooling & heating speed as needed.
• For most jobs, about 400 CFM per ton when cooling is desirable.
• INSTALLATION IS TO BE ADJUSTED TO OBTAIN TEMPERATURE RISE WITHIN THE RANGE SPECIFIED ON THE RATING PLATE.
• The chart is for information only. For satisfactory operation, external static pressure should not exceed value shown on the rating plate. The shaded area
indicates ranges in excess of the recommended maximum heating static pressure.
• The above chart is for U.S. furnaces installed at 0-2000 feet. At higher altitudes, a properly de-rated unit will have approximately the same temperature rise
at a particular CFM, while ESP at the CFM will be lower.
