NOTES:
* Based on 77°F rise with 58°F potable water inlet temperature at 14 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-FIRED WATER HEATER TESTING STANDARD IWH-TS-1_MARCH 2003
