Larger ChimneysHearth & Home recommends that chimneys with largerdiameters than 6 inches (152mm) be fully relined. An over-sized flue can affect draft and impair performance and willallow increased build-up of creosote which is why a full relineis stongly recommended.NOTE: Masonry chimneys are significantly less than idealfor venting solid fuel appliances. A masonry chimney is notsubject to any temperature limit test, therefore a full relineis strongly recommended.
