Understanding Chimney Cap Draft Inducers
Chimney cap draft inducers, also known as auto-draft or chimney draft inducers, are devices installed on top of chimneys to improve the draft and prevent downdrafts caused by wind or negative pressure. When the draft is insufficient, smoke and other combustion byproducts can back up into the home, causing health hazards and property damage.
A chimney cap draft fan works by creating a negative pressure zone that pulls exhaust gases out of the chimney and into the atmosphere. It does this by increasing the velocity of the flue gases, which in turn creates a pressure differential that helps to overcome any wind or negative pressure that may be present.
There are several factors that can affect the draft in a chimney, including wind, negative pressure, and downdraft. Wind can cause a sudden increase in pressure at the top of the chimney, which can force exhaust gases back down into the home. Negative pressure, on the other hand, can be caused by exhaust fans, air conditioning units, or other appliances that are vented to the outside. Downdraft occurs when the air pressure inside the chimney is lower than the pressure outside, causing smoke and other combustion byproducts to be pushed back into the home.
