MAKE−UP
BOX
Refer to figure 17 for schematic wiring diagram and trou-
bleshooting and table 12 and figure 18 for field wiring.
1 − Select circuit protection and wire size according to the
unit nameplate. The power supply wiring must meet
Class I restrictions.
2 − Holes are on both sides of the furnace cabinet to facili-
tate wiring.
3 − Install a separate disconnect switch (protected by ei-
ther fuse or circuit breaker) near the furnace so that
power can be turned off for servicing.
4 − Before connecting the thermostat or the power wiring,
check to make sure the wires will be long enough for
servicing at a later date. Remove the blower access
panel to check the length of the wire.
5 − Complete the wiring connections to the equipment.
Use the provided unit wiring diagram and the field wir-
ing diagrams shown in table 12 and figure 18. Use
18−gauge wire or larger that is suitable for Class II rat-
ing for thermostat connections.
6 − Electrically ground the unit according to local codes or,
in the absence of local codes, according to the current
National Electric Code (ANSI/NFPA No. 70) for the
USA and current Canadian Electric Code part 1 (CSA
standard C22.1) for Canada. A green ground wire is
provided in the field make−up box.
NOTE − The G60DF(X) furnace contains electronic
components that are polarity sensitive. Make sure
that the furnace is wired correctly and is properly
grounded.
7 − One line voltage HUM" 1/4" spade terminal is pro-
vided on the furnace integrated control. Any humidifier
rated up to one amp can be connected to this terminal
with the neutral leg of the circuit being connected to
one of the provided neutral terminals. See figure 19 for
control configuration. This terminal is energized in the
heating mode when the combustion air inducer is oper-
ating.
8 − One line voltage EAC" 1/4" spade terminal is provided
on the furnace integrated control. Any electronic air
cleaner rated up to one amp can be connected to this
terminal with the neutral leg of the circuit being con-
nected to one of the provided neutral terminals. See
figure 19 for control configuration. This terminal is en-
ergized when the indoor blower is operating.
9 − One 24V H" terminal is provided on the furnace control
terminal block. Any humidifier rated up to 0.5 amp can
be connected to this terminal with the ground leg of the
circuit being connected to either ground or the C" ter-
minal. See figure 19 for control configuration.
10 −Install the room thermostat according to the instruc-
tions provided with the thermostat. See table 12 for
field wiring connections in varying applications. If the
furnace is being matched with a heat pump, refer to the
instruction packaged with the dual fuel thermostat.
Indoor Blower Speeds
1 − When the thermostat is set to FAN ON," the indoor
blower will run continuously on the low speed when
there is no cooling or heating demand.
2 − When the G60DF(X) is operating in the high−fire or low−
fire heating mode, the indoor blower will run on the cor-
responding heating speed.
3 − When there is a cooling demand, the indoor blower will
run on the cooling speed.
