We have a problem with our range being flush against the wall. Right now it is sitting forward 4 inches.

We have a gas pipe that is coming out of the wall, going through our cabinets, making a U-turn, and ending at the shut-off valve. Both the pipe and the valve are preventing the range from sitting flush up against the wall. What is the remedy here?! We think the plumber may be able to move the shut off valve over to be inside the cabinet to the left of the range. That will gain us an inch. But then the pipe that is coming out of the wall is there, still blocking! Someone had mentioned removing the backing to the Wolf range and gaining more space that way. But that sounds incredibly scary and wrong to me. Has anyone encountered this problem? We are in a NYC co-op building from the 50s. And I can't believe no one saw this coming. But that's another story. Thanks!!
