WARNING
Failure to follow this warning could result in personal injury,
death, or property damage.
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.

Field-Supplied Electrical Box on Furnace J-Box Bracket See Fig. 25.
JUNCTION BOX RELOCATION
NOTE: If factory location of J-Box is acceptable, go to next section
(ELECTRICAL CONNECTION TO J-BOX).
NOTE: On 14" wide casing models, the J-Box shall not be relocated
to other side of furnace casing when the vent pipe is routed within the
casing.
1. Remove and save two screws holding J-Box. (See Fig. 24.)
NOTE: The J-Box cover need not be removed from the J-Box in order
to move the J-Box. Do NOT remove green ground screw inside
J-Box. The ground screw is not threaded into the casing flange and
can be lifted out of the clearance hole in casing while swinging the
front edge of the J-Box outboard of the casing.
2. Cut wire tie on loop in furnace wires attached to J-box.
3. Move J-Box to desired location.
4. Fasten J-Box to casing with two screws removed in Step 1.
5. Route J-Box wires within furnace away from sharp edges,
rotating parts and hot surfaces.
1. Remove cover from furnace J-Box.
2. Attach electrical box to furnace J-Box bracket with at least
two field-supplied screws through holes in electrical box
into holes in bracket. Use blunt-nose screws that will not
pierce wire insulation.
3. Route furnace power wires through holes in electrical box and
J-Box bracket, and make field-wire connections in electrical
box. Use best practices (NEC in U.S. and CSA C22.1 in
Canada) for wire bushings, strain relief, etc.
4. Route and secure field ground wire to green ground screw on
J-Box bracket, OR FURNACE FAIL TO OPERATE.
5. Connect line voltage leads as shown in Fig. 27.
6. Reinstall cover to J-Box. Do not pinch wires between cover
and bracket.
Electrical Box on Furnace Casing Side. See Fig. 25 and Fig 27.
1. Select and remove a hole knockout in the casing where the
electrical box is to be installed.
NOTE: Check that duct on side of furnace will not interfere with
installed electrical box.

CAUTION
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.
FURNACE MAY NOT OPERATE
WARNING
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.
FIRE HAZARD
з ЫФЫЭМОЧЭЯФ ЭСТТЫЭМЧСТН
WARNING
Failure to follow this warning could result in personal injury or death.
Blower access panel door switch opens 115V power to control.
No component operation can occur. Do not bypass or close
switch with panel removed.
See Fig. 27 for field wiring diagram showing typical field 115V 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 HAZARD
WARNING
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 ANSI/NFPA 70-2008 and Canadian Electrical
Code CSA C22.1 or local codes to minimize personal injury if an
electrical fault should occur.
This may consist of electrical wire, conduit approved for electri-
cal 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.
ELECTRICAL SHOCK AND FIRE HAZARD
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 8 for equipment electrical
specifications.
U.S. installations: Make all electrical connections in accordance with
National Electrical Code (NEC) ANSI/NFPA 70-2008 and any local
codes or ordinances that might apply. Canadian installations: Make
all electrical connections in accordance with Canadian Electrical
Code CSA C22.1 or authorities having jurisdiction.
Use a separate, fused branch electrical circuit with a properly sized
fuse or circuit breaker for this furnace. See Table 12 for wire size and
fuse specifications. A readily accessible means of electrical discon-
nect must be located within sight of the furnace.
NOTE: Proper polarity must be maintained for 115V wiring. If polarity
is incorrect, control LED status indicator light will flash rapidly and
furnace will NOT operate.
