The term Zero Clearance indicates that the particular fireplace can be enclosed using combustible materials. Depending upon the limitations of a specific zero clearance fireplace, these combustible building materials may be allowed to be installed against the body of the fireplace without fear of combustion or heat damage. However, some fireplaces may require installation using non-combustible materials such as metal studs and framing for the parts of the enclosure in the immediate vicinity of the fireplace. Please have a professional install your fireplace following the parameters presented in the installation instructions to ensure that it is installed using the correct materials.
Zero Clearance does not mean that you can place objects like furniture in front of or against the front of your fireplace. Furniture and curtains etc. should remain at least 48-inches from the front of your fireplace for safety
