How do I select a chimney pot that will function properly?
When selecting a chimney pot it is important to consider the top opening in relation to the fireplace opening, and the base dimensions in relation to the flue they are covering. This ratio to the top opening is often 1/15 to 1/20. The base inside dimension and the base outside dimension should be nearly as large or larger than the largest dimension of the flue they are being installed on. The base of the chimney pot should not impinge on the effective flue area of the flue by more than 3/4 of an inch. Many other factors such as fireplace chimney construction and house air pressure can affect proper chimney operation. Superior Clay’s chimney pot brochure and website has a color-coded chart to help you size your chimney properly.
