Good morning. New owner of an Enviro Mini just installed a couple of weeks ago. I may have gotten too aggressive with vacuuming and sucked up this flimsy gasket on the bottom of the firebox/Ash pan cover? Not sure if it really is even a gasket as it is not called out on the parts list anywhere? Has anyone seen this or know how I can get a replacement? Might just have to make one? Thanks! Jules
