CFM per Ton selec!ons range from 290 – 450
Important:
When applied with zoning or a VSPD outdoor unit,
the CFM/Ton must be set to 400
Gas Hea!ng CFM shown is 2
nd
stage airflow. 1
st
stage
airflow is ~80% of the selected 2
nd
stage airflow and
cannot be adjusted.
Gas hea!ng CFM can be adjusted while the unit is
opera!ng in gas heat mode to enable the technician to
quickly adjust to the manufacturer's suggested heat
rise across the heat exchanger.
