Selecting Chimney Pots

In order to select a chimney pot that will function properly, consider the top opening in relation to the fireplace opening, and the base dimensions in relation to the flue it is covering. The top opening of the chimney pot should be in ratio to the fireplace opening. The chimney pot opening is often smaller than the effective area of the flue liner in order to reduce the effect of wind on the draft. Flue area is typically about 1/10 the fireplace opening area for square flues and about 1/12 for round flues. For chimney pots, this ratio is often reduced to 1/15 – 1/20. The base inside dimension should be nearly as large as or larger than the largest dimension of the flue the pot is being installed on. The chimney pot should not impinge on the effective area by more than 3/4 of an inch. The base of the chimney pot often fits over the flue liner but in any case the base of the chimney pot should not be smaller than the flue. Many other factors such as fireplace and chimney construction as well as house air pressure can affect proper chimney operation.
