The chimney sweep who couldn’t figure out how to clean my chimney somehow broke off what I think is stove cement. Do I need to apply more or is it okay to leave as is. It came off the back right corner which you can see in the pictures.
Also what do I use to affix gasket to the top oval plate on a Jotul F500?
