!CAUTION
FURNACE MAY NOT OPERATE
Failure to follow this caution may result in intermittent furnace operation.
Furnace control must be grounded for proper operation or else control will lock out. Control must remain grounded through green/yellow wire routed to gas valve and manifold bracket screw.
115-V WIRING
Verify that the voltage, frequency, and phase correspond to that specified on unit rating plate. Also, check to be sure that service provided by utility is sufficient to handle load imposed by this equipment. Refer to rating plate or Table 7 for equipment electrical specifications.
U.S. Installations: Make all electrical connections in accordance with National Electrical Code (NEC) ANSI/NFPA
Canadian Installations: Make all electrical connections in accordance with Canadian Electrical Code CSA C22.1 or authorities having jurisdiction.
!WARNING
FIRE HAZARD
Failure to follow this warning could result in personal injury, death, or property damage.
Do not connect aluminum wire between disconnect switch and furnace. Use only copper wire.
Use a separate, fused branch electrical circuit with a properly sized fuse or circuit breaker for this furnace. See Table 7 for wire size and fuse specifications. A readily accessible means of electrical disconnect must be located within sight of the furnace.
