How do I increase the flame height on an outdoor gas fire pit?
I need help finding a device or method to increase the flame height. The fire ring is 8 ft long, so I need a device that increases the gas flow or pressure to increase the flame height. Gas piped in directly from my residence and is at a standard rate/flow. Any ideas or solutions out there?

Raise the burner pipe closer to the grill.
Increase the pressure from the tank to allow the gas to flow harder and faster. Or, add pipes in the oopening so there is more openings for gas to escape from.
If this fire pit has been used and is not new, the pipes may need to be cleaned to remove corrosion. Remove the lava rocks and use a clean wire brush on the piping.
Depending on the size of the openings clean them with a needle tool, unbent paperclip (small one), or a darning needle (get your wife a new needle), don't enlarge the holes, leave them at their original size.
Use a compressor to clean out the dust and debris from inside the pipe. Clean up the mess and replace the lava rocks, turn on the gas, light and enjoy.
BTW there should be a pressure gauge somewhere along the pipeline, either at the entry to the fire pit or where it exits your residence. There should also be a flame adjustment valve. On older pits it's triangular shaped and moves from side to side to allow more or less oxygen to the burners.
