It was a bit of a challenge to figure out which valve was the correct replacement as the fireplace manufacturer went out of business several years ago. I made an educated guess and it worked. Since this is replacement valve for other applications, the unused ports are sealed off (by the installer) with provided pipe plugs. The plugs don't thread far enough into the body to be flush enough for the mounting brackets to fit properly. This is a very low clearance installation, so this almost did not work. However, with some creative use of flat washers and a shoehorn, we made it work. The valve itself works great at a reasonable price.
