Extention
Figure 20: TC42D Hearth extension.
This fireplace may be recessed up to
a maximum depth of 4½” from the
screen, this recess must be con-
structed from non- combustible mate-
rial. The space between the outside
lintels and the firebox must be
completely free of any debris and the
window with trim fitted must be able
to move freely. No building material is
permitted to protrude past the lintel
bars attached to the fireplace under
ANY circumstance.
Caution: While a hearth extension is not required and combustible flooring
materials may be brought directly up to the fireplace, many materials (such as
wood flooring) may not tolerate the radiant heat from this fireplace, resulting
in discoloration, shrinking and cracking. For this reason, we suggest a non-
combustible hearth that is no more than 1” above the bottom of the fireplace.
If thicker, fireplace must be raised accordingly.
Caution: Hearth extensions thicker than 1” will interfere with the safety screen
and window frame when opening.
