Nocomponent operation can occur. Do not bypass or closeswitch with blower door removed.! WARNINGSee Fig. 34 for field wiring diagram showing typical field 115--vwiring. Check all factory and field electrical connections fortightness.Field--supplied wiring shall conform with the limitations of 63_F(33_C) rise.ELECTRICAL SHOCK AND FIRE HAZARDFailure to follow this warning could result in personalinjury, death, or property damage.The cabinet MUST have an uninterrupted or unbrokenground according to NEC ANSI/NFPA 70--2011 or localcodes to minimize personal injury if an electrical faultshould occur. In Canada, refer to Canadian Electrical CodeCSA C22.1. This may consist of electrical wire, conduitapproved for electrical ground or a listed, grounded powercord (where permitted by local code) when installed inaccordance with existing electrical codes. Refer to thepower cord manufacturer’s ratings for proper wire gauge.Do not use gas piping as an electrical ground.! WARNINGFURNACE MAY NOT OPERATE HAZARDFailure to follow this caution may result in intermittentfurnace operation.Furnace control must be grounded for proper operation orelse control will lock out. Control must remain groundedthrough green/yellow wire routed to gas valve and manifoldbracket screw.CAUTION!115--V WiringFurnace must have a 115-v power supply properly connected andgrounded.NOTE: Proper polarity must be maintained for 115-v wiring. Ifpolarity is incorrect, control LED status indicator light will flashrapidly and furnace will NOT operate.Verify that the voltage, frequency, and phase correspond to thatspecified on unit rating plate. Also, check to be sure that serviceprovided by utility is sufficient to handle load imposed by thisequipment. Refer to rating plate or Table 9 for equipment electricalspecifications.U.S.A. Installations: Make all electrical connections in accordancewith the current edition of the National Electrical Code (NEC)ANSI/NFPA 70 and any local codes or ordinances that mightapply.Canada Installations: Make all electrical connections inaccordance with the current edition of the Canadian ElectricalCode CSA C22.1 and any local codes or ordinances that mightapply.FIRE HAZARDFailure to follow this warning could result in personalinjury, death, or property damage.Do not connect aluminum wire between disconnectswitch and furnace. Use only copper wire. See Fig. 32.! WARNINGUse a separate, fused branch electrical circuit with a properly sizedfuse or circuit breaker for this furnace. See Table 9 for wire sizeand fuse specifications. A readily accessible means of electricaldisconnect must be located within sight of the furnace.59SP5A
