The safety strips should extend from front of
the fireplace at least 1 ¹⁄₂" and should extend to
be at least flush with the sides. In the event a
wooden support is used to elevate the fireplace
above the floor, a “Z” type safety strip should be
fabricated and used to protect the front surface
of the wood support as well as the floor beneath
the hearth extension (
Figures 7 and 8
). The
safety strips should be tacked down to prevent
possible movement.
Note: The “Z” type safety strip is not supplied.
