Try a plumbing supply house. Webbs, Blodgetts are around me. You need a 10" chimney pipe adaptor. Selkirk, Hart Cooley, MG Duravent, Metalfab are all makers of class A pipe and have these adaptors to go from single wall pipe to there double wall pipe. Local firplace / stove shop maybe able to get as well. The home depots / Lowes only stock 6 and 8".
