WARNING
• Do not ground the oven to a gas-supply pipe or hot-water pipe.
• If connecting the ground wire to a grounded cold-water pipe, use a sep-
arate copper grounding wire (#10 minimum) and a clamp with an exter-
nal grounding screw. This pipe must have metal continuity to electrical
ground, interrupted by insulation. (Insulating materials must be jumped
with a minimum 4 AWG wire to establish continuity to ground.)
