Pizza oven cracked on inside

[fournil]

Hi All
I dried out our pre-built pizza oven as best as possible but on second round of firing I've developed what looks like some significant cracks on the inside as well as the outside. The outside cracks I've painted over using the paint provided but I need to know if the inside cracks are a problem or if they are to be expected in a climate such as that which we have in the north of England. I've attached some pictures - any guidance would be much appreciated.

Thanks

Mark

I'm pretty sure warranty will not be covering that crack. Unfortunately that is a very simple oven with limited application. Use it and plan to replace it as funds become available.
