Stone Age Fireplace
1.0 Introduction
Congratulations on becoming the owner of a Stone
Age Fireplace, manufactured by Stone Age
Manufacturing, Collinsville, Oklahoma.
Three generations of fireplace knowledge and
experience have gone into the design and
construction of the SA 24, 36 and 48 fireplaces.
Originally designed for a patio or back yard
installation, customer demand has brought this
fireplace into the house. An SA fireplace assembly
is shown in Figure 1.

It is recommended that this fireplace be installed
by a professional installer in an existing home
because of structural changes required, or by a
builder in new construction. Installation by a non-
qualified person may negate the warranty.
Keep these instructions for future use.

3.0 Installation of the Fireplace
Do not install this fireplace in a mobile home.
3.1 Preparations
Select wall location where all the minimum
distances, as shown in Table 2 can be met. Proceed
as follows. Numbers in ( ) are item numbers from
Table 1 and Figure 1.
Determine the height you want the firebox floor off
the finished grade. The legs (1) provided with the
kit are 18 inches tall and place the firebox about 24
inches above the finished grade. If this height is not
desirable, discard the legs and construct base from
concrete blocks.
If the unit is to be installed indoors, do not use the
legs (Item 1, Figure 1 and Table 1). Rather, install
the fireplace on a solid block base such as concrete
blocks or a cement pad.

WARNING: DO NOT USE LEGS FOR AN
INDOOR INSTALLATION. IN
THIS INSTALLATION, THE
VOID BELOW THE FIREBOX
COULD INADVERTANTLY BE
USED FOR STORAGE OF
COMBUSTIBLE MATERIALS,
WHICH COULD CREATE A
FIRE HAZARD.
Select a high temperature fire clay or refractory
cement and mix according to manufacturer’s
instructions. Several companies in the U.S. and
Canada sell refractory cement or fire clay including
Stone Age Manufacturing.
Once the fireplace is constructed you must wait at
least 28 days before building a fire to give the
cement adequate time to cure. This will provide
ample time for any water residue to evaporate,
eliminating the adverse reaction of the combination
of water and fire.
3.2 Assembly of Components
A. When the base is level and square, set the
baseplate (2). Level it from side to side and
front to back.
B. As shown in Figure 1, install the four sidewall
pieces (3) and the back header (6). Use one-
half inch of mortar between each section.
Smooth out mortar and make sure sections
remain level.
C. After installation of the back header (6), install
the firebrick inside the firebox. Line the floor,
then the back and then the sides. Apply
approximately ¼ to ½ -inch thick layer cement
to the back of the brick, and approximately 1/4
–inch mortar joint around the brick.
D. Continue with the installation with front
header, throat and flue (7, 8 and 9). The front
header (7) can be arched or straight. Add as
many flue sections (9) to reach desired
chimney height.
E. If installing the SA 48-inch fireplace, install
the throat-to-flue adapter, item 11, shown in
Figure 2 and listed as item 11 in Table 2. It is
installed between items 8 and 9.
F. If installing a mantel and side trim, especially if
it is wood or other combustible materials,
make sure the minimum distances shown in
Table 2 are met.
G. Install the hearth (10). You are now ready to
install the exterior.
3.3 Installation of Additional Equipment
A decorative gas appliance (gas log) may be
installed in this fireplace if it meets the following
requirements.
A.A hole may be cut or drilled in the side, floor or
back wall to install piping for a gas supply.
B. The gas log must have an automatic shutoff
device.
C. Installation must comply with the Standard for
Decorative Gas Appliances for Installation in
Vented Fireplaces, ANSI Z21.60 (1991) or
American Gas Association draft requirements
for Gas-Fired Log Lighters for Wood Burning
Fireplaces, Draft No. 4 dated August, 1993.
D. It must also be installed in accordance with the
National Gas Fire Code, ANSI Z223.1.
3.4 Exterior finishing
The exterior finish may be either fabricated stone,
thin veneer or full bed depth natural stone, stain,
tile, brick, stucco or any material that is compatible
with concrete or masonry.
If exterior finish is going to be stucco, stain, tile or
manufactured thin stone, wrap outside of firebox
with metal lathe. Attach lathe to fireplace using
concrete nails or tapcons. Full bed depth or thin
veneer natural stone, full size brick, concrete
pavers or CMU block etc. do not require metal
lathe.
Make sure same refractory mortar is used.
4.0 Installation of Chimney
The chimney is completed by stacking as many
flue sections (9) as necessary to reach chimney
height. Chimney plumbing can either be straight
through the ceiling and through the roof, or if the
fireplace is installed on an outside wall, the
chimney can be external to the house.
WARNING: THIS FIREPLACE HAS NOT
BEEN TESTED FOR USE
WITH GLASS DOORS. TO
REDUCE THE RISK OF FIRE

4
OR INJURY, DO NOT
INSTALL GLASS DOORS.
4.1 Maintenance Clearances
When the chimney passes through a ceiling to an
upper floor, make sure the 2-inch clearance is
maintained with framing where it passes through
the ceiling. Exterior veneer attached directly to the
chimney measuring 2” or more is acceptable for
needed clearance.
WARNING: DO NOT PACK REQUIRED
AIR SPACES WITH
INSULATION OR OTHER
MATERIALS.
4.2 Secure Chimney System
As the chimney extends through the attic to the
roof, attach securing straps to rafters and joists as
required by local building code to provide stability.
4.3 Roof Exit
If roof opening is not present locate the point
where the chimney will exit the roof by plumbing
down to the center of the chimney. Drive a nail into
the roof to mark the center.
A. Measure to all sides of the nail and mark the
required opening, then cut a hole in the roof.
Remember that the hole is measured on the
horizontal, then projected to the roof. The hole
may then be larger, depending on the pitch of
the roof. See Figure 3.
Figure 3. Roof Penetration
B. Frame the opening, making sure that the
minimum 2-inch distance between the roof
and the chimney is maintained all the way
around if roof structure is constructed from
any combustible materials.
C. Continue to add flue sections (9), extending
the chimney through the roof. If the exterior
extension of the chimney is adjacent to a
combustible wall, make sure the 2-inch
minimum clearance is maintained around the
chimney. Exterior veneer materials applied
directly to the chimney that are a minimum of
2 inches in thickness including mortar are
acceptable for clearances.
D. Install roof flashing appropriate to the roof
pitch.
4.4 Height of Chimney
Figure 4 illustrates the proper height of the
chimney top. Correct height depends on the
chimney’s location on the roof and distance from
the peak of the roof. Surrounding trees, other
buildings and hills may also be a consideration.
Figure 4. Chimney Height

5
If the chimney top is not high enough, unusual
downdrafts may occur, resulting in undesired
smoke. For a more thorough explanation of the
figure 4 illustration it is basically the 2/10 rule.
Once the center of your chimney is ten feet away
from the roof, it should then be extended an
additional two feet in height. This means the
chimney does not have to extend above the peak of
the roof. Once it is ten feet away and extended two
feet the height is sufficient but should never be
shorter than three feet in height from where it
penetrates out of the top side of the roof.
4.5 Install Damper
A. If installing the Lyemance damper at the top of
the chimney, following instructions contained
with the damper. Figure 5 shows the proper
orientation of the damper in the chimney.
B. Connect the pull cable at the cable guide of the
damper and drop through the chimney.
Figure 5. Install Damper
C. Install bracket towards the front of the firebox
wall, about 20 inches off the firebox floor.
This will contain the damper operating cable.
Use a ¼” masonry bit to avoid cracks in the
firebrick. See Figure 6.
Figure 6. Install Bracket
D. Insert the pull cable through the bracket and
adjust the length as shown in Figure 7 in the
open and closed positions.

Check damper to make sure it opens and closes
properly.
4.6 Install Top Cap
Install the top cap over the damper following the
instructions provided. This will protect the
chimney from rain, birds, animals and leaves.
