1. Blower performance for gas heat includes maximum number of heat tubes available for each tonnage.<br />
2. Blower performance includes two-inch throwaway filters.<br />
3. ESP (External Static Pressure) given is that available for the supply <strong>and</strong> return air duct system. All internal resistances have been<br />
deducted from the total static pressure of the blower.<br />
4. “Turns Open” refers to the setting of the variable pitch motor sheave, where “0 Turns Open” is fully closed.<br />
5. W = Watts<br />
