Home located on side of hill: When the wind blows over a hill toward your
home, the wind will fall. This could cause a down-draft into your chimney.
Some common solutions to correct down-drafts are to add a chimney cap
with a weather vane (wind direction cap), add height to the chimney or add
a power venter.
Tall trees near your home: If you have trees that are near to and higher
than your home, a down-draft can occur when the wind blows. Correct the
same way as if you live on the side of a hill or in a valley.
