Orifice Chart
The burner valves in this grill have a specific BTU rating. This means that the amount of gas coming from each orifice is
controlled to create the BTU. The holes in the orifices themselves are drilled to different sizes so as to allow the proper
amount of gas to flow through them. Please note the chart below as an easy reference for the various orifice opening sizes for
the valves in the grill.
