●Note: If the chimney passes through the combustible wall, please make sure to put this glass stone into the wall. The size of the eyeglass stone is the right size for the chimney diameter. Do not cut. The glasses should be at least the thickness of the wall. If there is any gaps inside the wall, please fill the gap completely with the glass board insulation. There may be stains (light brown) or slight unevenness on the surface when manufacturing the glasses stones, but this is not a problem with quality
