I have NG in the house, running thru the crawl space. The gas runs thru a regulator after the meter and just inside the house before it splits off to the hot water heater and to the gas fire log. There is another regulator on the line to the gas fire log. The new range has a regulator built ion. Do I need another in line regulator to the range?
I wouldn't think so but to be safe you need to verify what the line pressure is on the existing line (the regulator feeding it should be marked). Then compare this pressure to the manufacturer's rating for the stove to be sure it's within the acceptable range.
