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.

WARNING

EDGES OF SHEET METAL HOLES MAY BE SHARP. USE GLOVES AS A PRECAUTION WHEN REMOVING HOLE PLUGS.

CAUTION

LABEL ALL WIRES PRIOR TO DISCONNECTION WHEN SERVICING CONTROLS. WIRING ERRORS CAN CAUSE IMPROPER AND DANGEROUS OPERATION. VERIFY PROPER OPERATION AFTER SERVICING.

WIRINGHARNESS

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.

115VOLT 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 National Electric Code,ANSI NFPA70 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.

Line polarity must be observed when making field connections. Line voltage connections can be made through either the right or

TO AVOID THE RISK OF INJURY, ELECTRICAL SHOCK OR

DEATH, THE FURNACE MUST BE ELECTRICALLY

GROUNDED IN ACCORDANCE WITH LOCAL CODES OR IN

THEIR ABSENCE, WITH THE LATEST EDITION OF THE

NATIONAL ELECTRIC CODE.

Line voltage connections can be made through either the right or left side panel. The furnace is shipped configured for a right side 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 step 2.

WARNING

TO AVOID THE RISK OF INJURY, ELECTRICAL SHOCK OR DEATH, THE FURNACE MUST BE ELECTRICALLY GROUNDED IN ACCORDANCE WITH LOCAL CODES OR, IN THEIR ABSENCE, WITH THE LATEST EDITION OF THE NATIONAL ELECTRICAL CODE.

To ensure proper unit grounding, the ground wire should run from the furnace ground screw located inside the furnace junction box all the way back to the electrical panel. NOTE: Do not use gas piping as an electrical ground. To confirm proper unit grounding, turn off the electrical power and perform the following check.
