Footing requirements for indoor installations should
be determined based on local building code. Consult
with a structural engineer to determine the footing
requirements based on the overall height, and the
weight of fireplace, chimney, and finish materials. If
custom hearths or additional masonry structure is to be
attached to the fireplace kit, the footing dimensions
should be adjusted to include these customizations.
Use Stone Age’s Multi-Purpose Ready-Mix, or an-
other high temperature fire clay or refractory cement
suitable for indoor or outdoor use, and mix according
to manufacturer’s instructions.
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.
Stone Age products are designed to be assembled us-
ing a 3/8” fully bedded mortar joint for the kit pieces.
Do not “butter the edges” of the kit pieces.
Install the fireplace on a solid base, such as a cement
pad or concrete blocks. Two courses of 8” tall block
will set the floor height of the fireplace at approxi-
mately 19 inches from the floor.
WARNING: DO NOT USE RISER LEGS FOR
AN INDOOR INSTALLATION.
IN THIS INSTALLATION, THE
VOID BELOW THE FIREBOX
COULD INADVERTANTLY BE
USED FOR THE STORAGE OF
COMBUSTIBLE MATERIALS,
WHICH COULD CREATE A FIRE
HAZARD.
3.2 Assembly of Components
Components that become broken during shipment and
handling can be mortared back together providing 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 suggest-
ed that you first assemble the components without
mortar to familiarize yourself with how the compo-
nents fit together. See Figure 2.
During the actual assembly with mortar, ensure each
layer of the kit is plumb, level, and square before pro-
ceeding to the next step of the assembly.
A. Determine the height above the floor you want to
place the base plate (2). The base plate, without fire-
brick, will be 3” thick. If installing firebrick, the
base plate, plus firebrick, will be approximately 4 1/2
inches thick. Mortar and set concrete blocks into
place to reach the desired fireplace floor height. En-
sure the block base is level and square. Additional
blocks may also be laid in front of the kit’s base plate
to create a base for a hearth. See Figures 6 and 7.
