WIRING HARNESS
The wiring harness is an integral part of this furnace. Wires
are color coded for identification purposes. Refer to the wiring
diagram for wire routings. If any of the original wire as sup-
plied with the furnace must be replaced, it must be replaced
with wiring material having a temperature rating of at least
105°C. Any replacement wiring must be a copper conductor.
115 VOLT LINE CONNECTIONS
Before proceeding with electrical connections, ensure that the
supply voltage, frequency, and phase correspond to that speci-
fied on the unit rating plate. Power supply to the furnace must
be NEC Class 1, and must comply with all applicable codes. The
furnace must be electrically grounded in accordance with local
codes or, in their absence, with the latest edition of The Na-
tional Electric Code, ANSI NFPA 70.
Use a separate fused branch electrical circuit containing prop-
erly sized wire, and fuse or circuit breaker. The fuse or circuit
breaker must be sized in accordance with the maximum
overcurrent protection specified on the unit rating plate. An
electrical disconnect must be provided at the furnace location.
