A Little Bit About Chimney Fans
Chimney fans are incredibly important. Located on the top or bottom of your fireplace chimney, the electric fan assists in drafting. Often installed alongside the liner, a fireplace chimney draft fan is essential when your chimney’s flue is too small to draft naturally. The fan ensures that the fireplace gets enough air to burn cleanly with no problems.
A draft fan for the fireplace works by creating a negative pressure in the chimney. A partial vacuum is created, and this pulls the exhaust gases from the fireplace or gas stove up into the chimney and then to the outside. This allows the fire to burn cleanly and without smoke.
