Line Voltage Wiring
It is recommended that 115VAC line voltage be
supplied to the furnace from a dedicated branch
circuit containing the correct fuse or circuit
breaker for the furnace. See Table 10 (page 31).

IMPORTANT NOTE: An electrical disconnect
must be installed readily accessible from and
located within sight of the furnace. Refer to
the wiring diagram inside the control box
cover or Figures 40 - 45 (pages 34 - 39) for the
wiring of your particular unit. Any other wiring
methods must be acceptable to authority
having jurisdiction.

IMPORTANT NOTE: Proper line voltage
polarity must be maintained in order for the
control system to operate correctly. Verify
the incoming neutral line is connected to
the white wire and the incoming “hot” line is
connected to the black wire. The furnace will
not operate unless the polarity and ground
are properly connected as shown in Figure 25.

Route all electrical wiring to the left side of the
furnace. For installation of “A” Cabinet furnaces,
allow suffi cient slack in the wiring if an optional
cooling coil cabinet is added at a later time. Use
of copper conductors is recommended.
