Why is a UL listing important?
Most fireplaces consist of two things: the actual firebox (where the wood/gas burns), and the chimney. These are paired when purchased because they have been tested to work together safely. When a homeowner or builder introduces a component to that structure that has not been tested and certified by UL, it voids not only the warranty and UL listing of the fireplace, but puts it in violation of important safety building codes including the international mechanical, international residential, and international fire codes. Our goal as a manufacturer of decorative chimney shrouds is to provide a handcrafted decorative crown for your chimney that is not only visually more pleasing than a simple metal pipe, but a safe and functional piece of equipment.
