Low profile single tube linear burners/ log lighters with ½ male gas supply end. Quick and easy to replace any defective or rotting older log lighter with this quick and easy retrofit or to use as a standalone burner; or array of burners. No air mixer needed if to light the wood in your vented fireplace (as there is 20x more soot burning wood). 1-piece burner with twin flame holes down the perimeter (45 degree down from center on each side of the gas fire pit burner which makes for a wide flame path). The higher you turn it up, the wider dispersion the flames. If using an insert or a pan in a tabletop application, we recommend a minimum 7-10" in width and around 1-2" longer on the ends. Great for converting a linear wood burning fire pit into a gas burning fire pit or creating a custom gas fire feature from scratch! Burners and Rings: all of our burners work with Propane Gas AND Natural Gas and are made of the highest quality 316 marine grade non-magnetic stainless steel. This is the same stainless steel you see on cruise ships, not lessor ss304 "tool or grill grade" stainless that 90 percent of the other companies produce. Our easy to work with gas fire pit burners and parts allow anyone to make a personal, artsy, and yard or table enhancing fire feature; one that can be altered and customized, re-used from home to home, or brought from party to party. Our complete gas kits are made of straight forward parts; easy enough for most amateurs to use, and yet a dream for any DIY (Do It Yourself) or professional fire feature builder.
