WARNING
!
ELECTRICAL SHOCK AND FIRE HAZARD
Failure to follow this warning could result in personal injury,
and death, or property damage.
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.
24–V WIRING
Connect 24-v thermostat leads to 24-v terminal block on furnace
control. For proper cooling operation, Y wire from thermostat
MUST be connected to Y/Y2 terminal on furnace control, as
shown in Fig. 31. The 24-v terminal block is marked for easy
connection of field wiring. (See Fig. 36.) The 24-v circuit
contains a 3-amp, automotive-type fuse located on furnace
control. (See Fig. 36.) 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 control will flash code 24 when fuse
needs replacement.
NOTE: Use AWG No. 18 color-coded copper thermostat wire
for lengths up to 100 ft. (30.4 M). For wire lengths over 100 ft
(30.4 M), use AWG No. 16 wire.
