The wiring harness is an integral part of this furnace. Field alter-
ation to comply with electrical codes should not be required.
Wires are color coded for identification 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.

OLT INE ONNECTIONS
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 National
Electric Code, ANSI NFPA 70 and/or The Canadian Electric Code
CSA C22.1.
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 elec-
trical 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. For direct vent appli-
cations, 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.

AFTER SERVICING
Line polarity must be observed when making field connections.
Line voltage connections can be made through either the right or
left side panel. The furnace is shipped configured for a right side
(left side for counterflows) electrical connection with the junction
box located inside the burner compartment. To make electrical
connections through the opposite side of the furnace, the junc-
tion box must be relocated to the other side of the burner com-
partment prior to making electrical connections. To relocate the
junction box, follow the steps shown below.
NOTE: Wire routing must not to interfere with circulator blower
operation, filter removal, or routine maintenance.

electrical connection. To make electrical connections through
the opposite side of the furnace, the junction box must be relo-
cated to the left side prior to making electrical connections. To
relocate the junction box, perform the following steps.
1. Remove the burner compartment door.
2. Remove and save the two screws securing the junction
box to the side panel.
3. Relocate junction box and associated plugs and grommets
to opposite side panel. Secure with screws removed in
