The Penta burner designed for outdoor gas fire pits not only looks different, it burns different and equally as well with lava rock or decorative glass media. The patented design is only available from HPC- delivering a very uniform & full campfire effect to your fire pit – a dramatically different look than standard fire rings especially on lower settings. This is accomplished by utilizing holes drilled at the 12 o’clock position of the stainless steel tubing for a broader flame. If you enjoy your flame on low, this will not exhibit the ring pattern seen with some concentric fire rings.
