* Actual external static pressure (ESP) can be determined by using the fan laws (CFM
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.
† "Comfort mode" airflow values are shown in parenthesis. "Comfort mode" airflow is selected when the low-heat rise
adjustment switch (SW1-3) is OFF and the comfort/efficiency switch (SW1-4) is ON. Furnaces are shipped in this
configuration.
‡ Ductwork must be sized for high-heating CFM within the operational range of ESP.
†† 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.
