Our stainless steel Burner Ring Kits come complete with everything you need to start your Natural Gas (NG) outdoor fire pit project. We start with 304 stainless steel so your burner will remain trouble free in the outdoors. The burner tubes are inserted into the adjoining tube then welded for unrestricted gas flow. All of our flame holes are precession drilled not punched so there are no tabs pushed inside restricting gas flow. By using our stainless steel Burner Ring you have a corrosive resistant burner that will survive the harsh outdoor weather.Our connection kit has been assembled using matching components to assure the best performance i.e. TWO Non-Whistle flex lines, high-flow keyed main shut off ball, and a secondary shut off valve allowing you to disconnect your burner for any maintenance. All this adds up to exactly what you are looking for; the highest possible flames.Please note, your incoming gas line size needs to be matched to the size of your burner. On average you will need a half inch line for 6, 12, 18, 24 inch rings. The 24HC, 30, 36, 40 inch rings will most likely require a three-quarter inch gas line. The 40, 48 inch rings may need 1 inch or more more gas line. These are general guidelines and not meant to be used as suggested gas line sizes; you will need to consult your installer for the exact size of line needed. We always recommend that all gas products be installed and serviced by professionals that have been certified by the NFI or WETT. The installer must conform to any and all State and/or local codes.
