*
Actual external static pressure (ESP) can be determined by using the fan laws (CFM
2
proportional to ESP); such as,
a system with 1180 CFM at 0.5 ESP would operate at cooling airflow of 1050 CFM at 0.4 ESP and low-heating airflow
of 735 CFM at 0.19 ESP.
†
Low heat CFM when low-heat rise adjustment switch (SW1-3) and comfort/efficiency adjustment switch (SW1-4) on
control center are OFF.
‡
Ductwork must be sized for high-heating CFM within the operational range of ESP.
**
Wattage data provided is for the circulating blower with bottom return and does not include draft inducer, accessories,
or gas controls.
††
Operation within the blank areas of the chart is not recommended because high-heat operation will be above 1.0 ESP.
***
All airflows on 110 size furnace are 5% less on side return only installations.
