The Vacu-Stack Chimney Cap is the best solution for wind induced downdrafts on both masonry and prefabricated chimneys. It is designed to stop wind from blowing into the chimney regardless of the wind direction. Accelerated air flow around the Vacu-Stack causes flue gasses to flow up and out of the chimney.
This model is designed for a round Class A Double Wall Chimney and can be used on a masonry chimney with proper adapter sold separately.
April 9, 2007 Hi all, Just wanted to let you know how happy we are with the 5SA-1243. The house is situated on the north side of a hill. When the wind came from the south, we would have to shut down the wood stove due to smoking. I installed the cap last fall, and we have not had a problem since. Also, the chimney is cleaner! I guess because of the Ventura draw. Thanks.
