Clay Pots can be seen on the most enduring buildings throughout the United States and Europe. They add a majestic touch to the buildings they are placed on. Clay Pots have a long life span in fact, often the clay pot itself will outlast the modern buildings it is attached to. Once the clay pot survives kiln firing at temperatures of 2000 degrees Fahrenheit or more, it will be able to survive the harshest of conditions.
In order to select a chimney pot that will function properly, it is important to consider the top opening in relation to the fireplace opening, and the base dimension of the chimney pot in relation to the flue it is covering.
The top opening of the 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. Many other factors, such as fireplace chimney construction and house air pressure can affect proper chimney operation.
