It will work, and in certain circumstances it's legal, but doesn't meet
current code. In your case, the manufacturer specifically calls for a
120/240 volt three wire circuit, which you don't have. My guess is that this
cooktop pulls more current through the neutral than the manufacturer wants
to go through a shared neutral-ground.

Thanks for the information. I just hooked it up so the two hot wires
(black and white) from the service are connected to the black and red
wires coming from the cooktop. I then connected the copper wire from
the service to the white wire from the cooktop. All seems to work fine.
Should I jump from the copper/white wire connection to a screw on the
metal frame box? It mayl be a while (maybe several weeks) before an
electrician can come out if necessary. Is there a problem with this
setup for a while? I think my previous cooktop had a similar
arrangement where the common and ground where connected, although that
top didn't have a fan. Thanks again for any advice.

But is it acceptable to code; presumably there is a jumper to connect the
frame to the neutral.
On a dryer it would be fine, but they plug in. Is is also fine on
permanently wired machines, or is that considered new work?

It'll work

Would be OK to temporarly connect the white (I assume common) wire
from
the cooktop to the copper ground wire until I can get an electrician
out to run a new conductor?

I want to wire a new Jenn Air Radiant downdraft cooktop. The wire
from
the breaker only has three wires (Black,White, and Copper). I
checked
the Black and White which were both "hot'. The directions say I
need
a
3 wire 120/240volt circuit). The cooktop has three wires in the
connection box - balck, red, and white ( No copper). Do I connect
the
Black and Red wires from the cooktop to the balck and white "hot"
wires
form the breaker.? What do do with the white from the cooktop and
the
copper from the breaker? Thanks
