Main Electrical Power
Requirements
Verify that the power supply complies with the unit
nameplate specifications.
•
Inspect all control panel components; tighten any
loose connections.
•
Connect properly sized and protected power supply
wiring to a field-supplied/installed disconnect switch
and to the main power terminal block (HTB1) in the unit
control panel.
•
Install proper grounding wires to an earth ground.
Through-the-Base Gas Installation
Note:
Through-the-Base Gas is not available with Low
NOx gas furnace option, digit 34 = A.
The gas supply line must extend 4
⅝
-inch
above the base
pan. The “Through-the-Base Gas” kit is located in the Heat
Vestibule compartment. To gain access to the kit, remove
the Heat Compartment access panel.
1. Remove the pipe assembly strapped to the manifold.
Unscrew 90° elbow from 6½-inch nipple and slide
rubber grommet off of nipple.
2. Remove the plastic plug from the hole in the center
post and insert the grommet removed from
6½-inch pipe nipple.
3. Using pipe sealant, attach the 90° elbow to the gas
supply line.
4. Disconnect the 5-inch pipe nipple and union from the
“Through-the-Base Gas” kit assembly.
5. Using pipe sealant, attach the 6½-inch nipple and gas
shutoff assembly to the 90° elbow on the gas supply
line.
6. Using pipe sealant, attach the 5-inch pipe nipple and
union to the street el attached to the gas valve.

WARNING
Hazardous Voltage w/Capacitors!
Failure to disconnect power and discharge capacitors
before servicing could result in death or serious injury.
Disconnect all electric power, including remote
disconnects and discharge all motor start/run
capacitors before servicing. Follow proper lockout/
tagout procedures to ensure the power cannot be
inadvertently energized. Verify with an appropriate
voltmeter that all capacitors have discharged.
For additional information regarding the safe discharge
of capacitors, see PROD-SVB06A-EN.
WARNING
Proper Field Wiring and Grounding
Required!
Failure to follow code could result in death or serious
injury. All field wiring MUST be performed by qualified
personnel. Improperly installed and grounded field
wiring poses FIRE and ELECTROCUTION hazards. To
avoid these hazards, you MUST follow requirements
for field wiring installation and grounding as described
in NEC and your local/state electrical codes.
