What is a key purpose of a chimney chase?

The primary purpose of a chimney chase is to conceal the chimney, providing a barrier that can hide the flue and other components from view. This helps in maintaining the overall aesthetic of the building, as a chimney can often disrupt the visual harmony of a structure. A chimney chase typically consists of a framed enclosure that covers the chimney, which can be finished in a material that blends with the rest of the building. This not only enhances the visual appeal but also serves practical functions by protecting the chimney from weather elements.

While the chase adds to the building's aesthetics, the central function is its role in concealing the chimney itself. Other options, such as enhancing ventilation or supporting the roof structure, are not primary functions of a chimney chase. A chimney's design and installation are primarily focused on ensuring proper function and safety rather than serving as a structural or ventilation component beyond its own operational needs.
