Installation Instructions Connecting to a Three Wire Electrical System with External Ground - Where Local Codes Permit 4 AWG wire (minimum) Insulating device warning • Do not ground the appliance to a gas supply pipe or hot water pipe. • If connecting the ground wire to a grounded cold water pipe, connect using a separate copper grounding wire (No. 10 minimum) and a clamp with an external grounding screw. The grounded cold water pipe must have metal continuity to electrical ground and must not be interrupted by insulating materials. Any insulating materials must be jumped, with a minimum, 4 AWG wire to establish continuity to ground. Clamps Bare metal Insulated Pipe Jumper note If the junction box has been 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. Incoming Power To connect the green appliance conduit wire to a grounded cold water pipe: 1. Separate the wires coming out of the appliance conduit. 2. Connect the white wire from the appliance conduit to the white (neutral) supply wire in the junction box. 3. Connect the black wire from the appliance conduit to the black (L1) supply wire in the junction box. 4. Connect the red wire from the appliance conduit to the red (L2) supply wire in the junction box. 5. Connect the green wire from the appliance conduit to a grounded cold water pipe as shown. Jumper any insulating materials as shown above with a length of No. 4 copper wire. Securely clamp the wire to bare metal at both ends.
