* Permissible limits of voltage range at which unit will operate 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.
‡ Length shown is measured 1 way along wire path between unit and service panel for maximum 2 percent voltage drop.
** Time-delay type is recommended.
Piping should be pressure tested in accordance with the current
edition of the NFGC, local and national plumbing and gas codes
before the furnace has been connected. In Canada, refer to current
edition of NSCNGPIC. If the pressure exceeds 0.5 psig (14-in.
wc), gas supply pipe must be disconnected from the furnace and
capped before pressure test. If test pressure is equal to or less than
0.5 psig (14-in. wc), turn off electric shutoff switch located on
furnace gas valve and accessible manual shutoff valve before test.
After all connections have been made, purge lines and check for
leakage.
WARNING
!
FIRE OR EXPLOSION HAZARD
Failure to follow this warning exactly could result in serious
injury, death, or property damage.
Never test for gas leaks with an open flame. Use a
commercially available soap solution made specifically for the
detection of leaks to check all connections. A fire or explosion
could result causing property damage, personal injury or loss
of life.
Gas line grommet (factory-supplied loose parts bag) should be
used when installing gas piping. Gas line entry hole filler plug
should be installed in unused gas line entry hole. (See Fig. 30.)
NOTE: The gas valve inlet pressure tap connection is suitable to
use as test gauge connection providing test pressure DOES NOT
exceed maximum 0.5 psig (14-in. wc) stated on gas valve. (See
Fig. 58.)
The gas supply pressure shall be within the maximum and
minimum inlet supply pressures marked on the rating plate with
the furnace burners ON at HI-HEAT and OFF.

See Fig. 31, 32, and 50- -57 for field wiring diagram showing
typical field 115-v and 24-v wiring. Check all factory and field
electrical connections for tightness.
WARNING
!
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury
or death.
Blower access door switch opens 115-v power to furnace
control. No component operation can occur. Do not bypass or
close switch with panel removed.
Field-supplied wiring shall conform with the limitations of
63°F (35°C) rise.
CAUTION
!
UNIT MAY NOT OPERATE
Failure to follow this caution may result in intermittent
unit operation.
Furnace control must be grounded for proper operation or
control will lock out. Control is grounded through
green/yellow wire routed to gas valve C-terminal and burner
box screw.

115-V WIRING

Before proceeding with electrical connections, make certain that
voltage, frequency, and phase correspond to that specified on the
furnace rating plate. Also, check to be sure that service provided
by power supply is sufficient to handle load imposed by this
equipment. Refer to rating plate or Table 6 for equipment
electrical specifications.
The furnace must be electrically grounded in accordance with
local codes; or in the absence of local codes, with the National
Electric Code ANSI/NFPA 70 and/or the Canadian Electric Code,
CSA C22.1, Part I, if an external electrical source is utilized.
