I have a Grizzly woodstove and our homeowners insurance company is going to cancel our policy, unless I can prove that the woodstove is UL approved. I have looked all over the woodstove and do not find any stickers or markings and if there was any I believe that have fallen off. Anybody that can help with any suggestions, where I can look or purchase a manual, it would be highly appreciated. Also, maybe a recommendation on insurance companies that approve woodstoves.
