True or False: Factory-built chimneys are not required to be of masonry construction.

Factory-built chimneys do not have to be constructed of masonry; they can be made from various materials, including metal and other non-masonry components. The regulation allows for these alternative materials, provided they comply with relevant safety and performance standards. This flexibility in construction materials is often intended to enhance the efficiency and functionality of heating systems while also accommodating specific design and installation requirements.

While some building codes may have particular stipulations regarding chimney construction, the general premise holds that factory-built chimneys are not limited to masonry alone. This understanding underscores the importance of staying updated on local building codes and manufacturer specifications as they can dictate the necessary requirements for installation and materials used in chimney construction.
