If I need a total height of 5 feet of above roof piping, how much more do I need to add to your kit?

The piping for this stove will typically come 3-4 feet outside of a standard roof with a 0-6.5" pitch. If additional pipe is needed, you will need to get more Class A (stainless steel) chimney pipe, which can be found on this page: DuraVent 6 - Inch Diameter Duratech Chimney Components. To avoid searching through the large amounts of options on the page, hit Ctrl+F and search for "24 Inch Length Chimney Pipe - Stainless Steel". This alone is what you will need if additional pipe is required for your setup.
