My gas log kit came with Robershaw 710-501 gas control valve. Once we had the logs installed, the flame was much too high for our small fireplace. The valve comes set to 3.5" W.C.; the 1751-005 Add-on regulator allows you to dial that down to 1.7" W.C. This is a much better "fit" for our fireplace as the flames remain well below the damper and give a nice effect. The price is a bit high for a relatively simple item, but it well made. I don't expect to ever have to mess with it again and will soon forget what I paid for it. I definitely recommend it; took me a while to research the problem and figure out what to do, but once I did, the installation was a snap and it did the trick.
