NOTES:
*Based on 77°F rise with 58°F potable water inlet temperature at 8 GPM heat source flow rate. Heat source temperature was 180°F.
**Minimum Coil output based on continuous boiler operation over 30 minutes. See Section III for additional considerations.
All data obtained through testing in accordance with GAMA Indirect Water
