NOTICE: Hearth extension design must be determined
before installation of replace.
If the replace is placed on the oor the maximum height
of a nished raised hearth is 2 in. (51 mm), if you want
a higher raised hearth the replace must be placed on a
platform.
The replace will t a framed opening of:
SA36: 41-1/2 in. (1054 mm) tall and 43 in. (1092 mm) wide,
SA42: 41-1/2 in. (1054 mm) tall and 49 in. (1245 mm) wide.
WARNING! Risk of Fire! You must comply with all
minimum air space clearances to combustibles. DO NOT
pack required air spaces with insulation or other materi-

WARNING! Risk of Fire! Comply with all minimum clear-
ancesspecied.
• A minimum 3/4 in. (19 mm) air clearance must be
maintained at the back and 3/4 in. (19 mm) to the sides
ofthereplaceassembly.
• Chimney sections at any level require a 2
in. (51 mm) minimum air space clearance
between the framing and chimney section.
Figure 3.5 shows a typical framing (using 2 x 4 lumber)
of the replace, assuming combustible materials are
used. All required clearances to combustibles around the
replace must be adhered to. See Figure 3.2. Any framing
across the top of the replace must be above the level of
the top standoffs.
CAUTION! Risk of Cuts/Abrasions. Wear protective gloves
and safety glasses during installation. Sheet metal edges
are sharp.
WARNING! Risk of Fire! Prevent contact with sagging,
loose insulation.

insulation.
• Secure insulation and vapor barriers.
• Provide minimum air space clearances at the sides and
backofthereplaceassembly.
E. Secure and Level the Fireplace
This replace may be placed on either a combustible or
noncombustible continuous at surface. Follow the in-
structions for framing in Section 3. Slide the replace into
position. Be sure to provide the minimum 3/4 in. air clear-
ance at the sides and 3/4 in. at the back of the replace.
The replace should be positioned so the face of the non-
combustible material on the replace will be ush with the
face of the drywall on the walls.
Level the replace and shim as necessary.
The nished cavity depth must be no less than 23 in.
(584 mm) from the nished backwall to the outside of front
wall framing.
