Here is what I have 16" new gas pipe, my plans are building a small pit probably about 36" long. I think I am going to make my firebox about 20" long.
Here are my questions, do y'all think that would be overkill?
Next question I have tried the calculator on the opening from box to pit, but I'm still confused on total opening size. Can somebody make this easier for me and tell me what y'all think?
