Finish Requirements; Shipping Weights - Lennox EST-36 Installation Instructions Manual

LENNOX HEARTH PRODUCTS • ESTATE™ SERIES WOOD-BURNING FIREPLACES • MODELS EST-36, EST-42, EST-50 • INSTALLATION INSTRUCTIONS
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 values"
when multiple materials are used.
WarnIng
the crack between the fireplace
and the hearth extension must be
sealed with a noncombustible
material.
WarnIng
When installing hearth extension
in front, the fireplace must be
raised if height of hearth exten-
sion exceeds 7" (178mm) above
the bottom of the fireplace (see
Figure 49 ).
7" (178mm) Max.

fInIsh rEquIrEmEnts

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 (such as stone,
tile, or brick) 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
noncombustible caulking material only to seal
the black metal facing to the surround material
on the finished wall.
