Gas StoveTop installation - for 36"x21" top, how large under the counter? - gas stove installation

We are trying to determine the best furnace gas to the meter size. Age of heating is 36 "wide x 19 cm deep, and we have only about 1 inch front and 1" on the back of the upper part. We want to buy a new stove, but most are 21 cm deep. I know that is the lower part of the intestine, "if you will, probably a little shorter all the way around the summit, which is on the tile and granite. All shops that sell the stoves are not plumbers, and really wants just the sale. They are not aware that this kind of detail.

Has anyone installed a stove, or at least been there as a homeowner?
