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 left
side (right 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 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 Junc-
tion Box Relocation section.

(HUMIDIFIER AND ELECTRONIC AIR CLEANER - 96% MODELS
ONLY)
The furnace integrated control module is equipped with line volt-
age accessory terminals for controlling power to an optional field-
supplied humidifier and/or electronic air cleaner.
The accessory load specifications are as follows:
Turn OFF power to the furnace before installing any accessories.
Follow the humidifier or air cleaner manufacturers’ instructions
for locating, mounting, grounding, and controlling these acces-
sories. Accessory wiring connections are to be made through the
1/4" quick connect terminals provided on the furnace integrated
13. Locate hose #4 and cut a cut off a 4” straight section
and discard the radius end.
14. Connect the 4” straight section of hose #4 to the
100º elbow and the PVC pipe and secure with red
clamps.
15. Connect the hoses to the trap inlets and secure with
silver clamps, drain trap outlet must point to the

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 and/or The Canadian Elec-

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.
Connect hot, neutral, and ground wires as shown in the wiring
diagram located on the unit’s blower door. 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.
