Finish Requirements; Installation Components - Superior TM-4500 Series Installation Instructions Manual

The sum of all "R values" is: .70 + .10 +. 038
+ .10 = .938
This would NOT be an acceptable combination
of material for the hearth extension since the
total calculated "R value" of the materials used
is under the required "R value" of 1.19. An
additional layer of insulating materials must
be used.
Note: Also see NFI Certification Manuals for
expanded explanation on calculating "R val-
ues" when multiple materials are used.
WARNING: THE CRACK BETWEEN THE
FIREPLACE AND THE HEARTH EXTEN-
SION MUST BE SEALED WITH A NON-
COMBUSTIBLE MATERIAL.
WARNING: WHEN INSTALLING HEARTH
EXTENSION IN FRONT, THE FIREPLACE
MUST BE RAISED IF HEIGHT OF HEARTH
EXTENSION EXCEEDS 7" (178 MM) ABOVE
THE BOTTOM OF THE FIREPLACE ( SEE

FINISH TO YOUR TASTE
There are a wide variety of "finished looks" for
these fireplaces, from formal wall decor with
elaborate mantels to rustic wood paneling or
warm brick facings.
Only noncombustible materials like stone, tile,
brick, etc., may overlap the black front facing.
Do not extend these materials beyond the black
facing and into the firebox area. Be sure not to
interfere with the installation and operation of
glass doors or block the upper or lower grilles.
Seal all joints between the black facing and wall
surrounds to prevent air intrusion. Use non-
combustible caulking material only to seal the
black metal facing to the surround material on
the finished wall.
Combustible materials may project beyond the
sides of the fireplace opening as long as they
are kept within the shaded areas illustrated in
Figure 50 .
