NOTES:
1) Indirect water heaters with an asterisk (*) will not achieve their catalog rating due to inadequate boiler water fl ow and/or 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
