BLOWER PERFORMANCE SPECIFICATIONS
28
Rev. 2
1. Units are shipped without filter(s). CFM in chart is without filter(s).
2. All furnaces shipped as high speed for cooling. Installer should adjust blower speeds as needed.
3. INSTALLATION IS TO BE ADJUSTED TO OBTAIN TEMPERATURE RISE WITHIN THE RANGE SPECIFIED ON THE
RATING PLATE.
4. The chart is for information only. For satisfactory operation, external static pressure not to exceed value shown on
rating plate. The shaded area indicates ranges in excess of maximum external static pressure allowed when heating.
5. The above chart is for U.S. furnaces installed at 0-2000 feet. At higher altitudes, a properly derated unit will have
approximately the same temperature rise at a particular CFM, while the ESP at that CFM will be lower.
