A:AnswerI had a question about the wireless module too. We're replacing an existing cooktop with this one. Our existing cooktop has a down draft exhause positioned within 1/8th of an inch of the rear of the current cooktop. I can't really tell from the pictures whether the wireless module extends beyond the dimension of the top or not. Does it?
A:AnswerThe surface housing the 5 gas rings are stainless steel and it is a seal set up for the gas ring. This makes cleaning fairly easy and straight forward for my household.
