Our Powder Coated HD Fireplace Steel Dual Row burner kit come complete with everything you need to start your indoor or outdoor fireplace or fire pit project. First we start with HD high grade steel and powder coat it black for additional longevity. With two rows of burners you will fill your fireplace or fire pit with flames. Our connection kit has been assembled using matching components to assure the best performance. We start with our 10" x 3/8" Non-Whistle Flex line and add fittings to connect our dual flame burner to your 3/8" OR 1/2" male flare stub coming into your fireplace. The 1/2 inch connection hub on both ends allows you to connect from either side. All this adds up to exactly what you are looking for in a fireplace flame burner; the highest possible flames! We strongly recommend that all 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.
