Orifice Chart
The different burner valves in this grill have different BTU ratings. This means that the amount of gas coming from
each orifice varies in order to create the BTU's. 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 different valves in the grill.
