13. Locate another hose #5 cut a 5.25" straight section and discard the radius end.
14. Connect the 5.25' straight section to the 100º elbow and the PVC pipe and secure with red clamps.
15. Mate trap inlets and hoses and secure with silver clamps, drain trap outlet must point to the original bottom of the
furnace.
16. Secure trap to furnace using two screws removed in step 2.
17. Refer to Field Supplied Drain section for instructions on field supplied / installed drain on outlet of furnace trap.

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 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.

ONNECTIONS
Before proceeding with electrical connections, ensure that the supply voltage, frequency, and phase correspond to that specified
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 pro-
tection specified on the unit rating plate. An electrical discon-
nect 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.
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 junc-
tion box located inside the burner compartment. To make elec-
trical 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.

UMIDIFIER AND
LECTRONIC
The furnace integrated control module is equipped with line voltage 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 accessories. Accessory wiring connections are to be made through the 1/4"
quick connect terminals provided on the furnace integrated control module. The humidifier and electronic air cleaner hot terminals
are identified as HUM and EAC. The humidifier and electronic air cleaner neutral terminals are identified as NEUTRAL. All field wiring
must conform to applicable codes. Connections should be made as shown. (See Figure 29.)
If it is necessary for the installer to supply additional line voltage wiring to the inside of the furnace, the wiring must conform to all
local codes, and have a minimum temperature rating of 105°C. All line voltage wire splices must be made inside the furnace junction
box.
