Make Electrical Connections

WARNING
Electrical Shock Hazard
Disconnect power before servicing.
Replace all parts and panels before operating.
Failure to do so can result in death or electrical shock.
IMPORTANT:
Electrical wiring, disconnect means and over current
protection are to be supplied by the installer. Refer to the
rating plate for the maximum over current protection,
minimum circuit ampacity and operating voltage. See "Wiring
Diagram".
Install an adequate sized branch circuit disconnect, per the
NEC, within sight of and readily accessible to furnace.
The cable or conduit and fittings connected from the
disconnect to the furnace wiring connections shall be rated
for outdoor use.
Check the furnace rating plate to determine whether the
system is rated single phase or three phase and follow the
appropriate instructions for connecting the pigtail leads.
When bottom entry is used for field supply wires, conduit
must be used to route the supply wires through the bottom
section of the cabinet into the burner and control
compartment. See Bottom Electrical Entry graphic.
Plug unused side entry holes with field-supplied plugs to
prevent moisture from entering the unit.
Low voltage wiring must be separated from line voltage
wiring.
