NOTICE:
Hearth extension design must be determined
before installation of fireplace.
If the fireplace is placed on the floor the maximum height
of a finished raised hearth is 8-1/8 in. (206 mm), if you
want a higher raised hearth the fireplace must be placed
on a platform.
The fireplace will fit 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.

pack required air spaces with insulation or other materi-
als.
WARNING! Risk of Fire!
Comply with all minimum clear-
ances specified.
• 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 fireplace 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 fireplace, assuming combustible materials are
used. All required clearances to combustibles around the
fireplace must be adhered to. See Figure 3.2. Any framing
across the top of the fireplace 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.
•

install against vapor barriers or exposed
insulation.
• Secure insulation and vapor barriers.
• Provide minimum air space clearances at the sides and
back of the fireplace assembly.
E. Secure and Level the Fireplace
This fireplace may be placed on either a combustible or
noncombustible continuous flat surface. Follow the in
-
structions for framing in Section 3. Slide the fireplace 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 fireplace.
The fireplace should be positioned so the face of the non-

* If interior of chase will be drywalled, add the thickness to
this measurement.

material.
NOTE: Before framing up the chase, consider where and
how the chimney will run. If there are obstacles that might
be in the way, it may be necessary to make the chase
larger than shown to allow for offsets to be used. Refer to
offset chart on page 16 if needed.
