ELECTRICAL SHOCK, FIRE OR EXPLOSION
HAZARD
Failure to follow safety warnings could result in
dangerous operation, serious injury, death or property
damage.
Improper servicing could result in dangerous operation,
serious injury, death or property damage.
-- Before servicing, disconnect all electrical power to
furnace.
-- When servicing controls, label all wires prior to
disconnection. Reconnect wires correctly.
-- Verify proper operation after servicing.
-- Always reinstall access doors after completing service
and maintenance.

WARNING
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal
injury or death.
Blower door switch opens 115--v power to control. No
component operation can occur. Do not bypass or close
switch with blower door removed.
!
WARNING
See Fig. 36 for field wiring diagram showing typical field 115--V
wiring. Check all factory and field electrical connections for
tightness.
Field--supplied wiring shall conform with the limitations of 63

ELECTRICAL SHOCK AND FIRE HAZARD
Failure to follow this warning could result in personal
injury, death, or property damage.
The cabinet MUST have an uninterrupted or unbroken
ground according to NEC NFPA 70 or local codes to
minimize personal injury if an electrical fault should occur.
In Canada, refer to Canadian Electrical Code CSA C22.1.
This may consist of electrical wire, conduit approved for
electrical ground or a listed, grounded power cord (where
permitted by local code) when installed in accordance with
existing electrical codes. Refer to the power cord
manufacturer’s ratings for proper wire gauge. Do not use
gas piping as an electrical ground.
!
WARNING
FURNACE MAY NOT OPERATE HAZARD
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.
CAUTION
!
115--V Wiring
Furnace must have a 115-v power supply properly connected and
grounded.
NOTE : Proper polarity must be maintained for 115-v wiring. If
polarity is incorrect, control LED status indicator light will flash
rapidly and furnace will
NOT operate.
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 11 for equipment
electrical specifications.
U.S.A. Installations : Make all electrical connections in accordance
with the current edition of the National Electrical Code (NEC)
NFPA 70 and any local codes or ordinances that might apply.
Canada Installations : Make all electrical connections in
accordance with the current edition of the Canadian Electrical
Code CSA C22.1 and any local codes or ordinances that might
apply.
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. See Fig. 35.
! WARNING
Use a separate, fused branch electrical circuit with a properly sized
fuse or circuit breaker for this furnace. See Table 11 for wire size
and fuse specifications. A readily accessible means of electrical
disconnect must be located within sight of the furnace
J--Box Installation
FIRE OR ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal
injury, death, or property damage.
High voltage field connections must be located in J--Box
with furnace, or in field supplied external disconnect
mounted to furnace.
If field--supplied manual disconnect switch is to be mounted
on furnace casing side, select a location where a drill or
fastener cannot damage electrical or gas components.
!
WARNING
The J--Box must be used when field line voltage electrical
connections are made to the furnace wiring harness inside the
furnace casing. The J--Box cover is not required if a field--supplied
external electrical box is attached to the outside of the furnace
casing. The field ground wire and furnace main ground wire are
grounded when the J--Box bracket is attached to the furnace and
the field ground wire and factory ground wire are secured to the
bracket grounding screw. If the J--Box cover is not used, the field
