"Most wood stove manufacturers require a minimum stack height of at least 13-15 feet, measured from the floor of the stove. Code requires that all woodstove and wood fireplace chimneys must extend at least two feet above any part of the roof within ten feet. Given that topographical and atmospheric conditions can vary considerably from house to house, it is possible for a chimney to comply with these minimum specifications but still fail to extend upward into air of low-enough density to establish ambient updraft. It is not uncommon for fireplaces and stoves in houses that are surrounded by hills or trees, for example, or that are located in the high-density air that often surrounds large bodies of water, to need more chimney height than the minimum required by code"
