IN – FIELD APPLICATION
A. MIXING MORTAR FOR FIRE ROCK INSTALLATION
The mortar used when installing the Fire Rock fireplace and chimney system is available
from your Fire Rock dealer or distributor, the same dealer that sold you the Fire Rock
system.
This specially formulated mortar is low sand, polymer modified with heat resistant
additives and is designed to work as a “glue” rather than a typical joint provider.
This mortar must be used for your Fire Rock Warranty to be valid.
It is appropriate to use a trowel or grout bag to apply the mortar to firebox and smoke
chamber joints. This material is to be mixed according to the instructions on the bag and
troweled directly from the mixing pail. These joints should be completely covered and
the components stacked so as to result in a 1/16th to 1/8th inch joint and the excess
mortar should push (ooze) out and be scraped away. Use this product as an adhesive
rather than a traditional mortar, the thin coating described above (1/16th to 1/8th inches
thick) will work best.
Upon completion of the firebox and smoke chamber it is important to go back and
“butter” all joints. This procedure involves a final smoothing, inside and out, sealing all
joints and assuring a “no leak” installation.
B. FIREBRICK LINING THE FIREBOX
A 1 ¼” minimum firebrick (ASTM 1261) lining is required for an acceptable fire safety
level. The same Fire Rock mortar used for the firebox and chimney may be used to affix
the firebrick to the inner wall of the firebox. The firebrick may be installed one of two
ways.
1) Troweled joints: The mortar may be troweled on to the face of the firebrick
at a thickness of 1/16th to 1/8th inch and stuck to the presoaked inner wall of
the firebox.
2) Dipped joints: Add enough clean (suitable for drinking) water to the
mixed mortar to achieve a consistency that a typical firebrick floats with
roughly 40% of its mass above the surface. Too much water will reduce
strength.
A “brick to brick” (no mortar joints) installation will be the strongest; a mortar joint is a
weak spot.
The mortar will not develop its full strength until completely cured.

IN – FIELD APPLICATION (cont.)
C. BROKEN COMPONENTS
Components that become broken due to poor handling or shipping should be
mortared back together providing the breaks or cracks are clean and original
alignment and dimension can be maintained. Components broken into multiple
pieces or fragments must be discarded and replaced.
D. HINTS
a. If this is your first Fire Rock installation, it would only take a few extra
minutes to “dry stack” (erect without mortar) your firebox to gain a
better understanding of how the components go together. Then
disassemble and erect using Fire Rock Adhesive Mortar.
b. Use a level to assure all components are level and plumb as you erect
your fireplace and chimney.
c. Assure your baseplate is level and at a proper elevation so the finished
hearth height (including firebrick lining) is correct in relationship to your
finished floor height.
d. Realize that this is a two man job. Some of these components are too
heavy for one man to lift.
e. ALWAYS INSTALL IN ACCORDANCE WITH LOCAL CODES
E. GAS LINE APPLICATIONS
The Fire Rock fireplace may be drilled through with an ordinary masonry drill bit
to accommodate a natural gas connection. This natural gas connection may be
used to 1) incorporate and automatic shut-off device and/or 2) comply with the
Standard for Decorative gas appliances for installation in Vented Fireplaces,
ANSI Z 21.60 or ANSI Z 21.11.2 The decorative gas appliance should be installed
in accordance with the National Fuel Gas Code, ANSI Z223.1.

IN – FIELD APPLICATION (cont.)
CLEARANCE REQUIREMENTS MAY BE LOCATED ON PRODUCTS LABEL ON EACH FIREBOX
If processed solid fuel logs are used:
DO NOT USE DIRECTLY ON FIREPLACE HEARTH, ALWAYS USE GRATE OR ANDIRONS
DO NOT POKE OR STIR THE LOGS WHILE THEY ARE BURNING, USE ONLY FIRELOG PRODUCTS WITH
WARNINGS AND CAUTION MARKINGS ON PACKAGING PRIOR TO USE
*** CAUTION ***
WHEN USING A DECORATIVE APPLIANCE, THE FIREPLACE DAMPER
MUST BE SET IN THE FULLY OPEN POSITION

OPERATING INSTRUCTIONS
This Section of the manual is to help you get maximum efficiency and maximum smoke
(particulate) reduction from your Fire Rock fireplace. If you should experience any difficulty or
have any questions concerning your fireplace contact your dealer/distributor or the Technical
Desk at Fire Rock Products, LLC.
The manufacturer’s recommendation for peak performance is to burn seasoned hardwood
(wood that has been cut and dry for 6 – 12 months) and place wood from side to side in the
firebox.
The manufacturer recommends a log grate be used in your fireplace for maximum performance.
The use of andirons is acceptable.
Building a fire for maximum efficiency: Because these fireplaces burn wood and extract heat so
efficiently a large fire will not only waste energy it usually will result in the home being too
warm for individual comfort.
THE FOLLOWING GUIDE WILL SERVE AS A GUIDE FOR OPERATING YOUR FIREPLACE
Building A fire without a log lighter:
1) Open the damper by pushing the damper handle up toward the top of the fireplace. The
damper handle is located in the top center of the firebox and extends down into the
firebox.
2) Twist 4 – 5 pieces of non-colored newspaper in a roll and place on the floor or grate of
the firebox
3) Lay several pieces of kindling on top of the newspaper
4) Place 3 or 4 pieces of firewood on top of the kindling
5) Light the newspaper
Building a fire with a log lighter
1) Open the damper as explained above
2) Lay several pieces of kindling across the log grate or andirons
3) Place 3 – 4 pieces of firewood on top of the kindling
4) A key near the front of the fireplace or on the hearth controls the gas to the log lighter.
Turn the key on and light the log lighter with a long fireplace match. Once the logs are
burning well, turn the log lighter off.

OPERATING INSTRUCTIONS (cont.)
Disposal of Ashes
Ashes should be placed in a metal container with a tight fitting lid. The closed container of
ashes should be placed on a noncombustible floor or on the ground well away from all
combustible materials, pending final disposal. If the ashes are disposed of by burial in soil
or otherwise locally dispersed, they should be retained in the closed container until all
cinders have thoroughly cooled.
Creosote Removal and Need for Removal
When wood is burned slowly, it produces tar and other organic vapors that combine with
expelled moisture to form creosote. The creosote vapors condense during the cooling
experienced while combustion by-products ascend up the chimney. This condensed
creosote accumulates on the flue lining. When ignited, this creosote makes an extremely
hot fire. The chimney should be inspected each year prior to the heating season to
determine if creosote build-up has occurred. If a significant layer of creosote has
accumulated (1/8th inch or more) it should be removed to reduce the risk of chimney fire.
The use of grates and/or andirons is recommended, not required, in Fire Rock fireplaces.
*** CAUTION ***
KEEP THE FRONT OF THE FIREPLACE CLEAR OF ALL COMBUSTIBLE MATERIALS
NEVER USE GASOLINE, GASOLINE TYPE LANTERN FUEL, KEROSENE CHARCOAL
LIGHTER FLUID, OR SIMILAR LIQUIDS TO START OR “FRESHEN UP” A FIRE IN THIS
FIREPLACE. KEEP ALL SUCH LIQUIDS WELL AWAY FROM THE FIREPLACE WHILE IT IS
IN USE.
IF PROCESSED SOLID FUEL LOGS ARE USED: DO NOT POKE OR STIR THE LOGS WHILE
THEY ARE BURNING. USE ONLY FIRE LOGS THAT HAVE BEEN EVALUATED FOR THE
APPLICATION IN FIREPLACE AND REFER TO FIRE LOG WARNINGS AND CAUTION
MARKINGS ON PACKAGING PRIOR TO USE
KEEP THESE INSTRUCTIONS FOR FUTURE USE

STEP ONE - FOUNDATION
***NOTE***
When used as an unvented gas appliance
enclosure (page 21-22) no special
foundation requirements apply.
The Fire Rock fireplace must be erected on a
non-combustible base with a non-
combustible 24” hearth extension in front of
the firebox opening and at least 8” on either
side of the firebox opening.
A concrete slab installation can be achieved
with or without the Fire Rock firebox
baseplate. In order to achieve the correct
finished hearth height, you may elect to
chalk line the outer dimensions and erect the
side blocks directly on the slab.
***NOTE***
If an outside air kit is to be used in your
installation, the cuts must be made in the
side block before installation.
Local codes must be followed and supersede
this manual.
