WIRING HARNESS
The wiring harness is an integral part of this furnace. Field
alteration to comply with electrical codes should not be
required. Wires are color coded for identication 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 tempera-
ture rating of at least 105° C. Any replacement wiring must
be copper conductor.
115 VOLT LINE CONNECTIONS
Before proceeding with electrical connections, ensure that
the supply voltage, frequency, and phase correspond to
that specied on the unit rating plate. Power supply to the
furnace must be N.E.C. Class 1, and must comply with all
applicable codes. The furnace must be electrically ground-
ed 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.
An electrical disconnect must be provided at the furnace
location.
NOTE: Line polarity must be observed when making eld
connections.
Connect hot, neutral, and ground wires as shown in the
wiring diagram located on the unit’s blower door. 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 congured for a right side (left side
for counterow) electrical connection with the junction box
located inside the burner compartment. To make electri-
cal 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.
NOTE: Wire routing must not interfere with circulator blower
operation, lter removal, or routine maintenance.
