Figure 4 - Multi-Zone Boiler Piping With Circulators
NOTE: When zoning with circulators, the furnished circulator pump should be used as one of the zone
pumps. Each stripped end of the electrical wires for the circulator pump inside the junction box should be
taped or wire nutted to prevent short circuits. Unplug the circulator pump wiring at the integrated boiler
control.
