4. (Draining the Collector Box) Locate hose #4 and place the radius end on the collector box drain port, secure with a silver
5. Locate hose #2, insert from outside the cabinet in the drain hole closest to the front of the cabinet, insert a coupling and
secure with a red clamp.
6. Mate coupling to hose #4 and secure with a red clamp.
7. (Draining the Vent Elbow) Remove plug from vent – drain elbow side port.
8. Locate hose #4 and place radius end on the side port of vent – drain elbow and secure with a red clamp.
9. Install cap on vent drain elbow barb fitting and secure with red clamp.
10. Insert PVC pipe into hose #4 and secure with a red clamp.
11. Locate hose #5, insert it from outside the cabinet in the drain hole farthest from the front of the cabinet.
12. Insert 100º elbow in hose #5 and secure with a red clamp.
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
16. Secure trap to furnace using two screws removed in step
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 dia-
gram 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-
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
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 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.
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 Junction Box Relocation section.
