The FAMCO WDCS Wind Directional Chimney Cap is designed to be most effective. The FAMCO research team has proven that the most effective draft inducing chimney caps are those that separate the wind stream as it flows over the cap and those that rotate to align with the wind direction. The Wind Directional Chimney Cap - WDCSS - does both to provide maximum drafting. In usage, the rotating hood is kept in proper position (relative to the wind) by the wind vane. Air movement past the hood creates a partial vacuum in the flue, enhancing draft efficiency and helping to prevent downdrafts. Quality constructed in 26 gauge Stainless steel.
The FAMCO WDCS Wind Directional Chimney Cap is engineered to slip around the O/D (outside diameter) of a single wall pipe and with the help of an adapter (WCASS) fit inside an insulated, double or triple wall pipe. Comes in a range of diameters from 5" to 14" with heights ranging from 14½ inch to 27 inch respectively.
The FAMCO WDCS Wind Directional Chimney Cap is manufactured by Famco in the United States and comes with a 1-year warranty against product defects and workmanship. If you have any questions about this product, please refer to the FAQs above or feel free to contact us by phone or email.
This is the second cap we've purchased, both from Famco, as we have 2 wood stove inserts, in our home (plus another in our garage/shop). The first works great! We were having issues with smoke being blown back down, behind the insert, which would then enter our living room. This would happen in high winds, blowing across the flat, open chimney. This cap also creates a much better draft, so our fires are started way more easily. We couldn't even start a fire if it was breezy outside (before). And the better draft helps in the summer, too. No more 'smell', it's so nice!
I expect this one will work the same, for our other fireplace!
