Hi, rebuilding a gas kiln I bought second hand, question is, the burner
port size and the exhaust port size(holes for gas in and out), is there a
math calculation for working this out or is there accepted techniques used.
The inside measurement of the kiln is about 1 meter or 3 feet square with
no fibre inside.

Thanks in advance
