NOTES:
1. Capacities are in MBH (kW), thousands of Btu
per hour (kiloWatts).
2. MBH (kW) values are based on a ∆t (temperature
difference) of 110°F (61°C) between entering air
and entering water. For other ∆t's; multiply the
MBH (kW) values by the factors below.
Correction factors at other entering conditions:
