My oven is pretty new - just built this fall. I do have vermiculite. I don't think it's related to the door since the wet spot is on the back of the oven - very far from the door. I think somehow the back floor is getting wet and the moisture is absorbed up the back. My roof is pretty flat - all stone and my chimney was just covered with mortar? (or concrete) and flashing and it was covered during the storm. Is it possible for the water to be so much that the stone or mortar around the stone absorbed the water and it finally reached the oven (past the insulation and more vermiculite)? |
