Gas fired furnaces, boilers and water heaters require a flue that has a good draft in it to get rid of the products of combustion after most of the heat has been removed. Newer appliances have fans and are called 'forced' or 'induced' draft venting. Older equipment and most boilers still rely on natural draft.
