18. Hearth Extension
A hearth extension must be installed with all fireplaces to protect the combustible floor in front of the fireplace from
both radiant heat and sparks.
The construction of, and materials used for a hearth extension are shown in Figures 34-36. A hearth extension of this
construction may be covered with any noncombustible decorative material and may have a maximum thickness as
per the illustration. Seal gaps between the hearth extension and the front of the fireplace with a bead of noncombustible
sealant.
