Dumb gas line question
So I am installing a new gas range and trying to change the gas and electrical connections to fit this new model. We are on a slab, so the gas line runs down the wall behind the range. The specs call for the gas line to be no higher than 2 inches off the floor. There is a metal bracket that runs all along the back of the range and they want the gas line to go below this bracket. Problem is, the gas fitting alone is 2 inches high! Even if we cut the 2 x 4 plate that runs along the floor behind the drywall down to the ground and ran the gas line so it sat directly on the floor, there is no room to actually turn the fitting to make it tight in the pipe. If we left room for that, we'd be above the 2 inches! So anyway, above this metal bracket there is a generous opening that the gas fitting would fit into just fine. Since this opening is much more accomodating, is there any reason we couldn't run the gas line out in that area? I just can't figure out why the specs are so specific to that one small area, when there is so much more room elsewhere. Any ideas?
