Notes:
1. Hydronic coil weight based on 14 fins per inch. Steam coil weight based on 6 fins per in. Coil width = length in direction of coil header, typically vertical. Coil length = length
of coil in direction of the coil tubes, typically horizontal and perpendicular to airflow. Unit sizes 21-30 have two stacked steam coils. Fan wheel size is diameter x length of
blade (width). Minimum airflow limit is for units with hot water, steam, or electric heat. There is no minimum airflow for cooling-only units.
2. For indoor units with optional baserail, add 6 inches to the height dimension.
