I am removing the gas cooktop, replacing it with a free standing gas range. The gas line currently enters the cabinet about 18" from the floor - far to high for a range! I need to remove the gas line and valve and mount it closer too the floor and not sticking out 6" into the area where the range will be. I'd like to install a gas outlet box in the wall to mount the valve. Who makes a gas line box that is suitable for a remodel installation?
