chimney pot. n. A short, usually earthenware pipe placed on the top of a chimney to improve the draft. chimâ²ney pot`. n. an earthenware or metal pipe atop a chimney, esp. to increase the draft and disperse smoke. [1820â30] Translations.
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 â 1/20.
