FirePlace Mantels Building Codes - National Standard
Municipal building codes are more strictly enforced as they relate to fireplaces than they are for many other decorative additions in a house.
The codes require the utmost in safety considerations because even when a fireplace is built exactly to code, it represents one of the biggest
dangers inside a residential building. Always check with your specific municipal codes to make sure that you are not going to be in violation,
whether you are installing a new fireplace or replacing one.
All the fireplace mantels on this website are non combustible and therefore require zero-clearance. This means that you can install any part of the fireplace as close as to
the fire as you want. The only requirement you need to satisfy is the hearth extension. However if you have a gas fireplace which does not burn solid fuel like woods, then
you do not need to satisfy the hearth extension requirement.
It is the
customer's responsibility to contact their local building code authority on fireplace mantels to determine if
the the mantel opening and the hearth extensions meet
the local building codes on fireplace mantels. If there is no code for mantel openings in relation to firebox openings
in your particular area, we strongly suggest the mantel surrounds meet the National Building Code.
The following is a reprint from the Standard Building Code.
