Once the fireplace is constructed you must wait at
least 28 days before building a fire to give 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
Components that become broken during shipment
and handling can be mortared back together provid-
ing the breaks or cracks are clean and the original
alignment can be maintained. Components broken
into multiple pieces must be replaced.
If this is your first Stone Age installation, it is sug-
gested that you first assemble the components with-
out mortar to familiarize yourself with how the
components fit together. See Figure 1.
A. Determine the height off the floor you want to
place the base plate (1). The base plate, plus fire-
brick, will be about 5 ½ inches thick. Set cement
blocks under the base plate to obtain the desired
height. Note that holes in many pieces of the kit
allow the placement of rebar and mortar for addi-
tional reinforcement, if desired.
B. When the base is level and square, set the base
plate (1). Level it from side to side and front to
back. See Figure 4.
C. Install the sidewall and back plate extensions
(2A) & (3), followed by the sidewall pieces (2) and
the lower and middle back plates (3A, 3B and 4A,
4B). Use 3/8” joint of mortar between each section.
Smooth out mortar and ensure sections remain lev-
el. See Figures 5, 6 and 7.
D. Lay a straightedge across the left and right side-
wall to ensure level is maintained.
E. Install the slanted sidewalls (6 and 7), and the
upper back plates (5A, 5B). Check the sides and
the top with a level. See Figure 8.
F. After installation of the back plates and side-
walls, install the firebrick inside the firebox, using
1/8-inch mortar joints. Cover the floor first with
1/8-inch high temperature cement. On the side
walls, stand the brick on its sides, and on the back
wall, lay the brick flat, leaving 1/2-inch air space
between the firebrick and fireplaces walls. Stack
