The Fire Pit Ring Burners are drilled instead of punched. They are much more accurate and do not leave debris inside the tube; eliminating the whistle effect.
The welding is machine done so parts fit together more accurately; providing for neater welds.
The gas transfer tubes that go from the hub to the rings are slanted upward toward the hub so water does not collect and run down into the valve; if the installation has one.
The gas transfer tube/hub construction is higher quality, more gas gets to the rings; offering larger flame output.
