Stock pot ranges are exactly what their name suggests, ranges to place individual stock pots on. They are made to be placed either on the countertop or directly on the floor, depending on your pot size. You will want to take note of the overall width of the unit as well as the gas inlet size. The gas inlet size indicates what diameter your gas supply line needs to be in order to operate the range. You will also need special hoses and couplings to attach the supply line to the piece of equipment, all have to have the same diameter as the inlet. You will want to measure the diameter of the largest pot that will be used on the range, so you get one that is big enough to accommodate your specific needs.
