A:Answer Hi Mrsfitty,
Unfortunately I'm not able to attach pictures or diagrams through this website, so you're best bet is to refer to the diagrams and information contained in the Installation Guide that comes with the NX58J7750SS. I can provide the dimensions, however. If installing the gas line through the floor, it's recommended to place it within 2" of the wall, and within a 17" of the left side. If installing the gas line through the wall, it should be located within 17" of the left side and no more than 9" above the floor.
Thanks for the question!
Ms. Samsung
