Hi All, I've acquired a Lange 6302A wood stove. It has the enameled stove pipe that goes up to the thimble. My question is this...what size thimble does it take? I'm wanting to install it in my older garage to heat it during the winter. I'm making a workshop out of it. I've looked out on the web and here but I can't find any info on the size of the thimble for a 4 1/2 stovepipe. Any and all help would be appreciated. Thanks.
