Hello all. I recently purchased this Estate Stove Company Heatrola. It has an oval opening for the stove pipe. The opening measures 8 3/8" x 3 7/8". I ordered an 8" oval to 6" round adapter and its way too big. Can anyone tell me what adapter I need. I would prefer double wall as I already have purchased the rest of the pipe in double wall. If a photo is needed I could provide one. Thanks for the help.
