Three-Wire Electrical Connection
IMPORTANT
No white-wire connection is needed for this 3-wire appli-
ance. If the junction box has a neutral (white) wire, you
must shield it to comply with the National Electrical Code.
1. Separate the wires coming out of the appliance conduit.
2. Connect the black wire from the appliance conduit to the
black (L1) supply wire in the junction box.
3. Connect the red wire from the appliance conduit to the
red (L2) supply wire in the junction box.
4. Connect the green wire from the appliance conduit to
the green (ground) wire in the junction box.
Installation Instructions
Three-Wire Electrical Connection With
External Ground
Steps in this procedure reference the middle- and lower-
right diagrams on this page.
WARNING
• Do not ground the appliance to a gas-supply pipe or
hot-water pipe.
• If you connect the ground wire to a grounded cold-
water pipe, use a separate copper grounding wire (#10
min.) and a clamp with an external grounding screw.
The grounded cold-water pipe must have metal con-
tinuity to an electrical ground and must not be inter-
rupted by insulating materials. Any insulating materials
must be jumped with a minimum 4 AWG wire to estab-
lish continuity to ground. (See Diagram B, right.)
NOTE
If the junction box was properly grounded by a licensed
electrician, the green (ground) wire from the appliance
conduit may be connected to the junction box using a
loop terminal.
1. Separate the wires coming out of the appliance conduit.
2. Connect the black wire from the appliance conduit to the
black (L1) supply wire in the junction box.
3. Connect the red wire from the appliance conduit to the
red (L2) supply wire in the junction box.
4. Connect the green wire from the appliance conduit to a
grounded cold-water pipe (A, right). Jumper any insulat-
ing materials (B, right) with a length of #4 copper wire.
Securely clamp the wire to bare metal at both ends.
