You should not install a piece of Vit Smooth black stove pipe within 3 times the diameter of the flue from combustible material, e.g. wood, plaster boards, etc. For example, a 4 inch (100mm) diameter piece of Vit Smooth black stove pipe should be 12 inches (300mm) away from combustible materials. When installing make sure the Vit Smooth black stove pipe is installed the correct way up - the smaller diameter should always be pointing downward. This is because all the condensates will stay within the flue system and not pass to the outside of stove pipe. Each joint should be coated with a jointing compound (fire cement or high temperature silicone sealant). This makes sure that no condensate can escape and spoil the appearance of the pipe.
You should make provision for inspecting and cleaning the chimney. This is particularly important on solid fuel applications. You can acheive this by installing a black pipe with an access door. It is recommended that chimneys serving solid fuel appliances be swept and maintained as frequently as necessary but at least once a year.
