The integrated boiler control is polarity sensitive. The
hot leg of the 115 VAC power must be connected to the
BLACK fi eld lead.
NOTE: All fi eld wiring must conform to local, state,
and national installation codes.
A disconnect switch equipped with overcurrent protec-
tion (e.g. a time delay-type fuse or inverse time, circuit
breaker) should be installed in the service line for
shutting down and protecting the boiler and electrical
system.
Since the boiler is entirely pre-wired at the factory,
it is only necessary to connect the building electrical
service lines to the junction box on the boiler. The
service lines to the boiler should be no smaller than 14
Ga., insulated copper wire with a temperature rating
of 60ºC, or greater.
Connect an equipment ground wire to the boiler in the
boiler junction box. . If wiring is run through metal
electrical conduit, it may not be necessary to run a
separate equipment ground wire. Consult local codes
and authorities for specifi c minimum requirements.
