I figured there has to be someone out there that has one and modified it to work but I found very little so I went and picked up some firebricks to put on the inside for insulation! I just insulated the cook area and not the bottom where the charcoal box is, not yet anyway.
I put the bricks all the way around the cook area and under the metal panels in the top that come off and then 2 between the charcoal and pizza stone as a buffer. Man let me tell you I put some small chunks off wood and lump charcoal in it, lit it and let everything absorb the heat and it was holding 550⁰-600⁰ and the stone was 450⁰ for a solid hour and half! I just used a frozen pizza for test purposes and it came out perfect in about 8 minutes. I just finished my deck and this is gonna be a nice addition to my little outdoor kitchen!
Anyway I hope this is useful to someone that bought this unit and is searching for some info on it like I was. I plan on doing some scratch made pies in the next couple days and I'll post up some pics.
