*The 60” and 72” require extra floor protection in addition to the
20” full depth hearth extension listed. The amount of additional floor
protection is dependent upon the opening height of the firebox, and
must be constructed of a non combustible material with a minimum
R-value of 0.30. For our standard sized box an additional 16” beyond
the hearth is required, for 1 height extension kit 40” is required, and
for 2 height extension kits 64” are required.
