Internal Circulator
This boiler is equipped with an internally installed Taco 0015e3 boiler circulator. In some piping systems, this circulator will provide
enough head for a direct connect system. See instructions starting on page 46 for Direct Connect System Piping. In all other cases,
this circulator will provide the proper boiler flow for a primary/secondary system piping. See instructions starting on page 50 for
Primary/Secondary System Piping.
The Taco 0015e3 is a variable speed, high-efficiency wet rotor circulator with an
ECM
permanent magnet motor that has three
different positions:
LOW, MEDIUM, and HIGH.
This circulator comes set at
HIGH.
This is the ideal setting for this boiler in most
cases. In some installations, the speed can be reduced, if the boiler temperature rise is smaller than the desired rise at the boiler’s
maximum input.
