Yes Phil, that is it. I have looked at many and chose this one. I hope it is the right choice? I am in the Oilfield here in Oklahoma and am thinking of cutting off 12 or so inches of 9 5/8" heavy wall casing and filling the inside with the brick and insulation and cutting a hole in the top for the JF#1. Then building sides to fit the casing and then hopefully I will have heat?
