Is the height of the stove and chimney connection different? With an adjustable box knee you can connect your stove to the chimney, even if the height doesn't fit. The flat knee or arch is available in various sizes and lengths in the fireplace shop. Up to 40 cm can be compensated with a box knee without having to drill a new chimney hole.
