* Permissible limits of the voltage range at which the unit operates satisfactorily.
# Unit ampacity = 125 percent of largest operating component's full load amps plus 100 percent of all other potential operating components' (EAC, humidifier,
etc.) full load amps.
{ Time ---delay type is recommended.
} Length shown is as measured one way along wire path between unit and service panel for maximum 2 percent voltage drop.

WARNING
!
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.
WARNING
!
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal
injury or death.
Blower access panel door switch opens 115- -v power to
control. No component operation can occur. Do not bypass
or close switch with panel removed.
See Fig. 25 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_F
(35_C) rise.

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 current edition of NEC NFPA 70 or
local codes to minimize personal injury if an electrical fault
should occur. 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.
!
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.
Make all electrical connections in accordance with current edition
of National Electrical Code (NEC) NFPA 70 and any local codes
