NOTES FOR TABLE 15 THROUGH TABLE 18:
• Blower performance includes dry coil and two-inch
filters.
• Blower performance for gas heat includes the maximum
number of heat tubes available for each tonnage.
• ESP (External Static Pressure) given is that available for
the supply and return air duct system. All internal resis-
tances have been deducted from the total static pressure
of the blower.
