*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.
{Comfort airflow values are shown in parenthesis. Comfort airflow is selected when the low --- heat rise adjustment switch (SW1 --- 3) is OFF and
the comfort/efficiency switch (SW1--- 4) is ON.
}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.
