Maybe you could get the cut-out replaced and upgraded to PME. If so, Then you could turn it around to face to the outside wall and move the outside cabinet to give access that way and provdie a heatproof sheild on the inside. Anyway off the top of my head that is all I can think of. Otherwise it is move the range over and provide access inside. Wow, what a headache!
P.S. perhaps they could even move it into the cabinet outside and the isolator to the inside.
