it has been brought to my attention in this forum that my stove has been installed incorrectly, so sure enough I went and did some measuring and it has indeed been installed wrong...the clearence from the top of the stove to the ceiling should be 58 inches minimum...mine is only 47 inches...what does a person do in this case? I did have a WETT installer do the work 3 yrs ago...should the installment be guaranteed?
