A chimney cap covers the entire chimney chase (the outside of the chimney) and, depending on the type of fireplace used, may include a chase pan, a decorative shroud, and wire mesh. A chimney pot is an earthenware or metal pipe at the top of a chimney, narrowing the aperture and increasing the updraft. Chimney pots are usually decorative and cover only the flue. A flue cap covers the flue only. Flue caps mass produced in a variety of materials and styles are readily available. Classic Copper Works only produces chimney pots and chimney caps.

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 may 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 copper chimney caps are based on the Venturi effect, solving downdraft problems by increasing the up draft constantly resulting in much higher fuel consumption.

Measuring Copper Chimney Caps

The diagrams below should help you determine your copper chimney cap size and provide measurements for ordering your new copper chimney cap or copper chimney pot. With copper chimney caps for a chimneys with a clay flue, the pipe diameter and location measurements are not needed; however, the distances from the edge of the chase to the flue are needed for all four sides. Please specify clay flue(s)'s distance from each outside edge of the chimney chase.


Important Things About Copper Chimney Caps

Be certain your chimney is square! Out of square chimneys require copper chimney caps that are 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" copper 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 us au ally 16". But be certain and measure your spark arrestor height before ordering your copper chimney cap!
