Copper Chimney Pots

A chimney cowl or cap is placed on top of the chimney to prevent birds and squirrels from nesting in the chimney. Chimney caps for clay flues feature a rain guard to keep rain from going down the chimney. A metal wire mesh is often used as a spark arrestor to minimize burning debris from rising out of the chimney and making it onto the roof. Although the masonry inside the chimney can absorb a large amount of moisture which later evaporates, rainwater can collect at the base of the chimney. Sometimes weep holes are placed at the bottom of the chimney to drain out collected water. Some caps stabilizes the draft rather than increasing it. Other chimney caps are based on the Venturi effect, solving downdraft problems by increasing the up draft constantly resulting in much higher fuelconsumption.

A chimney pot is placed on top of the chimney to inexpensively extend the length of the chimney, and to improve the chimney’s draft. A chimney with more than one pot on it indicates that there is more than one flue sharing the chimney.

How to Measure Your Chimney Cap

Fill in the blanks of the diagram below to determine your chimney cap size and help you provide measurements for ordering your new chimney cap or chimney pot. If you a chimney cap for a chimney with a clay flue, the pipe diameter and location measurements are not needed. Please specify clay flue(s)’s distance from each outside edge of the chimney chase.

Important Things to Note

Be certain your chimney is square! An out of square chimney requires a chimney cap that is the full length and or width of the chimney plus the amount it is out of square. The reason is that an out of square chimney is skewed. Thus, if your chimney is 1/2" out of square and the opposing sides on the out of square dimension are 36", you will need a 36 1/2" chimney cap on that dimension to compensate for the out of square. (See diagram below.)

Check the Size of Your Flue Spark Arrestor!

The Classic Bell copper chimney cap has a standard 24" inside height for the spark arrestor; the Suburban copper chimney cap a 20" height. This is more than sufficient for most chimneys, which are 16". But be certain and measure your spark arrestor height!
