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 front facing. Do not
extend these materials beyond the facing and
into the firebox area. Be sure not to interfere
with the installation and operation of glass
doors. Seal all joints between the facing and
wall surrounds to prevent air intrusion. Use
noncombustible caulking material only to seal
the 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 illus-
trated in

WARNING: THE CRACK BETWEEN THE
FIREPLACE AND THE HEARTH EXTEN-
SION MUST BE SEALED WITH A NON-
COMBUSTIBLE MATERIAL.

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.
