The wiring harness is an integral part of this furnace.
Wires are color coded for identication purposes. Refer to
the wiring diagram for wire routings. If any of the original
wire as supplied 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.

Before proceeding with electrical connections, ensure that
the supply voltage, frequency, and phase correspond to
that specied 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 National Electric
Code, ANSI NFPA 70 and/or The Canadian Electric Code
CSA C22.1.

Use a separate fused branch electrical circuit containing
properly sized wire, and fuse or circuit breaker. The fuse
or circuit breaker must be sized in accordance with the
maximum overcurrent protection specied on the unit
rating plate. An electrical disconnect must be provided at
the furnace location.
Connect hot, neutral, and ground wires as shown in the
wiring diagram located on the unit’s blower door. Metal
conduit is not considered a substitute for an actual ground
wire to the unit. For direct vent applications, the cabinet
opening to the junction box must be sealed air tight using
either an UL approved bushing such as Heyco Liquid
Tight or by applying non-reactive UL approved sealant to
bushing.
Line polarity must be observed when making eld
connections. Line voltage connections can be made
through either the right or left side panel. The furnace
is shipped congured for a left side (right side for
counterows) electrical connection with the junction box
located inside the burner compartment. To make electrical
connections through the opposite side of the furnace, the
junction box must be relocated to the other side of the
burner compartment prior to making electrical connections.
To relocate the junction box, follow the steps shown in the
Junction Box Relocation section.
