Quality burners are designed with 2 things in mind: pattern and gas capacity. Different burner options offer distinct flame patterns - so if you want all your fire pits to match the mood of your space, choosing the same burner is vital. Different burners are also optimized for different gas capacities. Choose wisely, and your fire pit will be running efficiently for longer than a burner meant for a larger tank. With that said, come to us if you're confused. Our team is well equipped to give you clarity.
