Custom Outdoor Fireplace with
Optional Arch Modification
Note: When reviewing
installation guidelines, plan for
any modifications before starting
construction of fireplace.
Note: The outdoor fireplace kit shown is constructed with Summit Stone “B” (7-1/4” x 10-7/8”)
units. Other Summit Stone unit sizes can also be used. For added design flexibility, any of the
other five sizes of Summit Stone landscape units can be substituted. Refer to the Summit Stone
Fireplace Kit Material Calculation Worksheet for units required if using multiple sizes.

Standard Outdoor Fireplace Installation Guidelines
Concrete Pad Preparation
Before beginning any outdoor fireplace project, make sure to check
with your local building inspector regarding open fire regulations in
your area.
It is recommended that any Summit Stone fireplace be installed on a 5"
thick concrete pad with rebar reinforcement and proper footings. The
pad should extend at least 6" beyond all sides of the proposed fireplace.
Note: The fireplace weighs approximately 8,000 lbs., including Summit
Stone units, steel lintel, firebrick and incidental block.

sales representative for information.
Note: Landscape adhesive should
only be used with Summit Stone units,
not on fire brick.

CAUTION
Safety Gear Required!
Note: Always wear
appropriate safety gear
when cutting concrete
units. Cutting should occur
away from the fireplace
area to avoid stains from
dust or residue.

12
Install Summit Stone units around the firebox
three courses high. This is the elevation for the
fireplace hearth.
10
Install and glue Summit Stone units laid on their
sides to form the perimeter of the firebox. Place, but
do not glue, the 6" concrete block supplied with the
components on their sides inside the firebox as a base.

15
Continue installing front hearth, firebox walls
and pillars as shown in successive pictures.
13
Install, but do not glue, fire brick to fit inside
the firebox (this will allow rainwater drainage of
firebox). It may be necessary to cut fire brick to
properly fit the interior of the firebox.
16
Note: Allow room for a 1/" gap between the
bottom row of the firebox and the front hearth.
This will help balance the Summit Stone units laid
perpendicular on the top of the hearth.
14
Construct and glue the front hearth and side
pillars on each front corner of the firebox using
Summit Stone units.

19
17
If your fireplace plan will include an optional front
arch, you will need to make slight installation
modifications on the firebox front walls and side
pillars. You cannot complete the side pillars until
the front arch is in place. Refer to the procedures for
Installing an Optional Front Arch explained later in this
guide for complete instructions.

procedures.

Firebox Liner
Installation
Line the sides and
back of the firebox
with fire brick
stacked on their
sides (6) rows high.
It is recommended
that the special
Heat Stop II
refractory adhesive,
supplied with
the components,
should only be used to adhere the surfaces
of fire brick to each other. Do not adhere
fire brick to the Summit Stone units.

Make sure the two specially cut left and right
Summit Stone lintel units are placed properly
on both sides of the firebox (top front) to
accommodate the lintel.

Continue
installing and
gluing Summit
Stone units to
complete the
firebox walls
above the lintel
and around the
sides and back.
25
Install steel lintel, supplied with the components,
across the top of the firebox at the front to
support units above.

Install Summit
Stone units laid
flat around the
top perimeter
of the firebox to
serve as the base
of the chimney.

Continue
installing
courses to
the top of the
chimney. Step
units in or out
1/" on each
side as shown
on successive
courses for
a tapered
chimney.
Note: Step units in or out 1/" on ALL 4 SIDES as shown
on successive courses for a tapered chimney. Stepping
units in or out by 1/"on each side equals one third of a
Summit Stone unit. This keeps alignment proportionate
and eliminates extra cutting of units.
32
Note: An arch feature will require approximately
(35) additional Summit Stone units, depending on the
arch design. You will also need the following materials:
• (1) ½" Plywood sheet (4' x 8')
• Diamond blade saw for cutting concrete
• Saws for wood
• (2) 2" x 4" Wood spacers
• Nails
• (15-20) Wood shims

Because of
tapering, the
chimney will
require using
the specially
cut / and /
Summit Stone
units supplied
with the
components.
If you run short of
/ cut units, simply use
two / cut units glued
together. Hide one
behind the other when
placing them in the
chimney course.

35
Measure the fireplace opening
to determine the center point
of the arch. Using sheets of
plywood, measure and cut
them to represent the opening
template. Using the center point
of the firebox as a reference,
mark and cut desired arch from
plywood. Cut two identical
plywood templates to serve as
center point
of the arch
the arch support that will hold up
the Summit Stone units.

To accommodate a front arch on your fireplace, stack
and glue (3) Summit Stone units on each side of the
hearth, laying them flat on top of each other.
Once these units are in place, continue installation
as directed for the back and sidewalls of the firebox,
interior fire brick and steel lintel. Instructions for
completing the arch will follow.
