why no Air mixer? your install pictures show one where you attach the fire ring. I also had to buy a coupler and additional pipe, and a 12" key so the key valve would work with my 12" x 4" paver pit stones. The product is well made, but doesn't take stone pit installs into consideration. Please consider this when purchasing.
