MASONRY CHIMNEY CHASE REBUILDS
The chimney in a factory-built fireplace that is prefabricated usually extends all the way through the roof. Sometimes these chimneys are encased in siding or simulated brick, and usually, they have a cap on top of the chimney that acts as a chase cover.
It is important to note that the safety of prefab fireplaces is thoroughly tested at the factory. In order to ensure their safety, they must be installed correctly. To avoid a house fire, it is imperative that you make sure that replacement parts are made specifically for your fireplace. In prefabricated chimneys, the housing is usually made of a synthetic material, similar to siding, and can be susceptible to wear or rot over time.
There are some prefabricated fireplaces that burn wood, some that burn gas, and some that burn both. Always burn the right fuel when you use a prefabricated fireplace.
