How to modify CC Sear Box to Natural Gas?

[KetoBBQ]

Anyone know how to modify the Camp Chef Sear Box so that it can be used with Natural Gas?

I've searched for answers on this, and even called Camp Chef. They do have an answer to a question on their web site that says that you can just connect NG to it, and it will work, but it won't heat up as much this way.

I understand that the orifice can be drilled out, but I don't know what size orifice would be optimal, and I don't know how the air mixture should be adjusted, either. Any help would be appreciated.

There are sites on the web that show orifice sizes for given BTU. Here's an example: https://www.grillparts.com/howto/conversion.htm
