CABLE INSTALLATION IN FURNACE J-BOX
Remove cover from J-Box.
Route BX cable into 7iS-inch diameter hole in J-Box.
Secure BX cahle to J-Box bracket with connectors approved
/br the type of cable used.
4. Secure field ground wire to green ground screw on J=Box
bracket.
Connect line voltage leads as shown in Fig. 25.
Reinstall cover to J=Box. Do not pinch wires between cover
and bracket.
24-V WIRING
Make field 24-v connections at the 24-v terminal strip. (See Fig.
24.) Connect terminal Y as shown in Fig 25 [br proper cooling
operation Use only AWG No 18, color-coded, copper thermostat
wire.
The 24-v circuit contains an automotive=type, 3-amp time located
on the control Any direct shorts during installation, serdce, or
maintenance could cause this fuse to blow If time replacement is
required, use ONLY a 3-amp fuse of identical size.
ACCESSORIES
1. Electronic Air (}leaner (EAC)
Connect an accesso_ Electronic Air (}leaner (if used) using

(if used) to the 1/4=in male quick-connect HUM terminal and
Co_>24V screw terminal on the coatlol board thermostat strip.
The HUM terminal is energized when pressure switch (PRS)
closes (See Fi b 24)
NOTE: A field-supplied, l I5-v controlled relay connected to
EAC terminals may be added if humidifier operation is desired
during blower operation
NOTE: DO NOT connect furnace control HUM tem_inal to HUM
(humidifier) terminal on Thermidistat-f_L Zone Controller or simi-
lar device. See Tl"*ermidistat

VENTING
The/i/mace shall be connected to a listed facto1T built chimney or
vent or a clay-tile lined masonw or concrete chimney Venting into
an unlined masonry chinmey or concrete chinmey is prohibited
When an existing Category I furnace is removed or replaced, the
original venting system may no longer be sized to properly vent
the attached appliances. An improperly sized Category I venting
system could cause the formation of condensate in the furnace and
vent, leakage of condensate and combustion products, and spillage
of combustion products into the living space.
