A WARNING
The cabinet MUST have an uninterrupted or unbroken ground
according to National Electrical Code, ANSI/ NFPA 70-1993
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.
The auxiliary junction box can be moved to the right-hand side of
the furnace when a right side power supply is desired. Remove the
2 screws holding the auxiliary junction box. Mount the junction
box on the right-hand side of the furnace (holes have been
predrilled in casing). The blower door interlock switch must also
be moved to the right side of the furnace due to the length of the
wiring harness. When moved, tuck the wiring harness behind the
clip provided to keep extra wire lengths out of the way,
NOTE:
Proper polarity must be maintained for 115-v wiring. If
polarity is incorrect, the microprocessor shuts off gas flow shortly
after the completion of ignition trial period.
panel for maximum 2 percent voltage drop.
24-V WIRING — Make field 24-v connections at the 24-v
terminal strip. (See Fig. 9.) Connect terminal Y as shown in Fig. 8
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 main control board. 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.
ACCESSORIES
1. Electronic air cleaner (EAC)
Two screw terminals (EAC-1 and EAC-2) are provided for
EAC connection. The terminals are energized with 115-v,
1-amp maximum during blower motor operation.
2. Humidifier (HUM)
Screw terminals (HUM-1 and C) are provided for 24-v
humidifier connection. The terminals are energized with 24-v,
0.5-amp maximum during heating blower motor operation.
