SWITCH
Fig. 29—Disconnect Switch and Furnace
Do not connect aluminum wire between disconnect switch
and furnace. Use only copper wire. (See Fig. 29.)
The cabinet MUST have an uninterrupted or unbroken ground
according to NEC ANSI/NFPA 70-2002 and Canadian Elec-
trical Code CSA C22.1 or local codes to minimize personal
injury if an electrical fault should occur. This may consist of
electrical wire or conduit approved for electrical ground when
installed in accordance with existing electrical codes. Do not
use gas piping as an electrical ground. Failure to follow this
warning could result in electric shock, fire, or death.
J-Box Relocation
1. Remove 2 screws holding auxiliary J-box. (See Fig. 30.)
2. Rotate J-box 180° and attach box to left side, using holes
provided.

LOCATION
Fig. 30—Relocating J-Box
If manual disconnect switch is to be mounted on furnace,
select a location where a drill or fastener will not contact
electrical or gas components.
Step 2—24-v Wiring
Make field 24-v thermostat connections at 24-v terminal block on
furnace control. Y wire from thermostat MUST be connected to
Y/Y2 terminal on control, as shown in Fig. 28, for proper cooling
operation. The 24-v terminal block is marked for easy connection
of field wiring. (See Fig. 32.) The 24-v circuit contains a 3-amp,
automotive-type fuse located on furnace control. (See Fig. 32.)
Any electrical shorts of 24-v wiring during installation, service, or
maintenance may cause fuse to blow. If fuse replacement is
required, use only a fuse of identical size (3 amp) and type. The
furnace control will flash status code 24 when fuse needs replace-
ment.
NOTE: Use AWG No. 18 color-coded copper thermostat wire for
lengths up to 100 ft. For wire lengths over 100 ft, use AWG No.
16 wire.
