Convenient snip, toller. Here's the *full* quote, which demonstrates clearly that you *did* do exactly what I *said* you did:
Here are the instructions from Jennair:
"The neutral of this unit is grounded to the frame through the green grounding wire. If used on new branch-circuit installations (1996 NEC), mobile homes, recreational vehicles, or in an area where local codes prohibit grounding through the neutral conductor, untwist or disconnect the green wire and connect the green wire to ground in accordance with local code. Connect the white neutral to the service neutral."
When you told him "the green wire has to be attached to the neutral".
Read the next to last sentence of the manufacturer's instructions: "...connect the green wire to ground..."
