NOTES:

1) Indirect water heaters with an asterisk (*) will not achieve their catalog rating due to inadequate boiler output.
2) When used with an indirect heater having a pressure drop less than 3.0 ft of head, the Taco 0013 can be installed

with up to 211 equivalent ft of 1” pipe.

3) Use isolation relay between Taco 0013 and FCM - see Figure 10.3
