WARNING: The cabinet MUST have an uninterrupted

or unbroken ground according to NEC ANSI/NFPA

70-1999 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 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 electrical shock, fire, or death.

J-BOX RELOCATION

1. Remove 1 screw holding auxiliary J-box. (See Fig. 19.)
2. Cut wire tie on loop in wires to J-box.
3. Locate box to desired location.
4. Fasten J-Box to casing with screw.
5. Remove U-shaped cut-out from outer door to clear J-Box.
6. Route J-box wires within furnace away from sharp edges

and hot surfaces.

CAUTION: 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.

B. 24–v Wiring
Make field 24-v connections at the 24-v terminal strip. (See Fig.

22.) Connect terminal Y/Y2 as shown in Fig. 21 for proper cooling

operation. Use only AWG No. 18, color-coded, copper thermostat

wire.
The 24-v circuit contains an automotive-type, 3-amp fuse located

on the control. Any direct shorts during installation, service, or

maintenance could cause this fuse to blow. If fuse replacement is

required, use ONLY a 3-amp fuse of identical size.
