3.0 Installation of the Fireplace
WARNING: DO NOT USE SUBSTITUTE
MATERIALS IN THE
ASSEMBLY, INSTALLATION
OR OPERATION OF THIS
FIREPLACE. TO DO SO WILL
VOID THE WARRANTY AND
MAY RESULT IN FIRE AND
PERSONAL INJURY.
It is most important that the Stone Age fireplace be
installed according to the following instructions. It is
also important that local building codes be consulted
and followed. Improper installation could result in:
• Overheating, leading to fireplace failure
• Cracks and settling because of poor founda-
tions
• Combustion of materials adjacent to the
fireplace.
WARNING: THIS FIREPLACE HAS NOT
BEEN TESTED WITH AN
UNVENTED GAS LOG SET. TO
REDUCE THE RISK OF FIRE
OR INJURY, DO NOT INSTALL
AN UNVENTED GAS LOG SET
INTO THIS FIREPLACE.
Do not install this fireplace in a manufactured or
mobile home.
3.1 Preparations
Select a location in the home plans or outdoor living
area where all the minimum distances, as shown in
Table 2 and Figure 3 can be met. Proceed as follows.
Numbers in ( ) are item numbers from Table 1 and
Figure 2. Ensure the base on which the fireplace is
to be installed is a solid and level foundation and is
composed of non-combustible material, such as con-
crete.
Due to varying climates, soil conditions, building
codes, construction methods and materials in differ-
ent geographical regions, Stone Age recommends
installers review local building codes, consult with
local building officials and/or a structural engineer
before beginning the construction of any Stone Age
product.
Pad or footings should be a monolithic pad con-
structed of steel reinforced concrete. Minimum foot-
ing specifications for fireplaces built on stable soil,
with overall height not exceeding 10 feet, are listed
in Table 3. Locations with unstable soil may require
a deeper footing or the addition of piers, to reach
more stable subsoil or bedrock. Areas with colder
climates may also require deeper footings or piers
that reach below the frost line to prevent frost heav-
ing. Piers should include steel reinforcement that
extends into the footing above. See Figure 4.
For taller applications, consult with an engineer to
determine the structural requirements based on the
overall height, and the weight of fireplace, chimney,
and finish materials. If custom hearths or additional
Figure 4. Footing with Piers - Cutaway View
Piers

masonry structure is to be attached to the fireplace
kit, the footing dimensions should be adjusted to in-
clude these customizations.
If local building code exceeds the manufacturer’s
specifications for footings, follow the local code.
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-oven is constructed you must wait
at least 28 days before building a fire to give ade-
quate time to cure. This will provide ample time for
any water residue to evaporate, eliminating the ad-
verse reaction of the combination of water and fire.
Stone Age products are designed to be assembled
using a 3/8” fully bedded mortar joint for the kit
pieces. Do not “butter the edges” of the kit pieces.
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.
The Caminetto™ ships as 3 pallets of material,
which must be assembled in numerical order. Begin
with pallet 1, then add the components from pallet 2,
and finish with the components from pallet 3. It is
recommended that you keep each pallet of materials
together until you are ready to install that pallet. The
components of Pallet 1 are shown in figure 5.
A. Start assembly with pallet 1. Begin kit assembly
by setting the base plate pieces (1 & 1C) on the
footing. Use a 3/8” joint of mortar between each
section, or slightly more if needed to reach the
proper overall width of 72” for this model. Level
the pieces from side to side and front to back. See
Figure 6.
B. On the first level, install the sidewalls (2) first,
then the back plates (3A, 3B, 3C). Use 3/8” joint of
mortar between each section, and repeat with all
remaining assembly steps, except for the firebrick.
Note that the back plates will be taller than the
sidewalls at this level. Smooth out mortar and en-
sure sections remain level. See Figures 7 and 8.

C. Install the second level sidewalls (2), followed
by the middle back plate pieces (4A, 4B, 4C). See
Figures 9 and 10.
D. Lay a straightedge across the left and right side-
wall to ensure plumb and level are maintained.
E. Install the slanted sidewalls (6 and 7), and the
upper back plates (5A, 5B, 5C). Check the sides
and the top with a level. See Figures 11 and 12.
F. After installation of the back plates and side-
walls, install the firebrick inside the firebox, using
full brick (2 ½” thick) on the floor and split (1 ¼”
thick) firebrick on the walls, with 1/8-inch mortar
joints. Cover the floor with 1/8-inch high tempera-
ture cement and install the floor before other sur-
faces. On the side walls and back wall, lay the
brick on its sides. Stack brick until it is 1 ½” to 2”
higher than the middle back plates (4A, 4B, 4C).
The red line shown is an approximate guideline.
See Figures 13, 142, and 15.

of fully non-combustible materials, not just a non-
combustible floor covering. When the hearth in-
stallation is complete, you are now ready to install
the exterior. See Figure 35.

3.3 Exterior finishing
The exterior finish of an indoor fireplace will vary as
compared to an outdoor application and may be lim-
ited depending on location in the home and framing
that encompasses the fireplace. Exterior veneers
may be fabricated stone, thin veneer or full bed depth
natural stone, tile, brick or stucco.
If the exterior finish is going to be stucco, stain, tile
or manufactured thin stone wrap outside of firebox
with metal lathe. Attach metal lathe to firebox using
concrete nails, tapcons, masonry or concrete anchors.
Natural stone, full bed depth or thin veneer, full size
brick, concrete pavers, CMU block, etc. do not re-
quire metal lathe.
Ensure same refractory mortar is used.
4.0 Installation of Chimney
4.1 Stone Age Masonry System
The Stone Age Masonry chimney system consists
of stacking Stone Age chimney blocks and in-
stalling an optional clay flue inside.
A. Place a clay flue inside the chimney block. The
holes in each corner of the chimney block allow the
placement of rebar and mortar for additional rein-
forcement, if desired.
B. Continue with stacking the outer blocks and
clay flues until the desired height is reached. Mor-
tar the flue sections together, and mortar the chim-
ney block sections together. There will be dead air
space between the flue and chimney block sections.
C. The chimney is completed by stacking as many
flue sections as necessary to reach chimney height.
D. Dual masonry chimneys taller than 12 feet
should be tied into the surrounding structure for
additional support, due to the weight of the dual
flue system. Consult with an engineer to determine
the best way to do so for your project.
E. If unit is under a roof and the chimney exit
opening does not already exist locate the point
where the chimney will exit the roof by plumbing
down to the center of the fireplace chimney. Drive
a nail into the roof to mark the center.
F. Measure to all sides of the nail and mark the
required opening, and then cut a hole in the roof.
Remember that the hole is measured on the hori-
zontal, and then projected to the roof. The hole
may then be larger, depending on the pitch of the
roof.
G. Frame the opening in the roof.
H. Continue to add flue sections, extending the
chimney through the roof.
I. Install roof flashing appropriate to the roof
pitch.
J. Use mortar to create a slope away from the clay
flue, running out to the edge of the finish material,
to assist with water drainage. Install the chimney
cap following instructions provided. This will pro-
tect the chimney from rain, birds, animals and
leaves.
4.2 Height of Chimney
Figure 36 illustrates the proper height of the chim-
ney 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.
If the chimney top is not high enough, unusual
downdrafts may occur, resulting in undesired smoke
spillage. For a more thorough explanation of the
figure 33 illustration, this is the traditional 2/10 rule.
Figure 36. Chimney Height
2’ Higher
Chimney Must be at Least 2’ Taller
Than Anything Within a 10’ Radius
10’ Radius
Chimney Must at Least 3’ Above
The Roof Penetration Point
3’ Above

12
The center of your chimney should be a minimum of
two feet higher than any roof or projection within ten
feet horizontally from the chimney center. This
means the chimney does not have to extend above
the peak of the roof. Once the chimney is ten feet
away and extended two feet above roof structure at
that distance, the height is sufficient, but it should
never be less than three feet taller than the point
where it penetrates the surface of the roof.
5.0 Operating Instructions
5.1 Safety Precautions
A fireplace and pizza oven can bring many hours of
enjoyment, warmth, and great cooking, if operated
and maintained properly. Certain safety precautions
must be observed to eliminate the dangers associated
with fire and provide a satisfactory fire with minimal
smoke. A pizza oven can easily generate tempera-
tures of 800°F or more, and can be dangerous if
proper clothing and tools are not used. Using the
fireplace and oven simultaneously will also require
taking extra precautions to protect against the poten-
tial for burns. Combustible materials in the vicinity
of the oven and fireplace openings may be at risk.
WARNING: WHEN OPERATING THE
CAMINETTO™, WEAR
PROPER CLOTHING AND USE
PROPER OVEN AND
FIREPLACE TOOLS WITH
EACH APPLIANCE. ENSURE
THAT COMBUSTIBLE
MATERIALS NOT REQUIRED
FOR THEIR OPERATION, ARE
KEPT AWAY FROM THE UNIT.
A. When burning wood use solid, seasoned wood
only. Do not use scrap wood or artificial wax
based logs, treated coal or woods dipped in pine tar
or pitch.
B. Never use gasoline or other combustible liquids
when starting a fire.
C. Keep a screen in front of the fireplace except
when tending the fire.
D. Keep combustible furniture/pillows at least four
feet from the opening.
E. Never leave the fire unattended.
F. Be extremely careful when adding wood and
handling fireplace tools. Never throw, kick or by
any other means force wood into the firebox as this
could damage the firebrick and fireplace walls that
could result in permanent damage and void the war-
ranty. Stress cracks from thermal cycling are nor-
mal.
G. Do not alter the fireplace or pizza oven to the
extent that it would jeopardize the structural integ-
rity of the unit. Drilling or cutting a hole for a gas
line, fresh air vent or ash dump is acceptable. Use
only Stone Age authorized equipment with this
fireplace.
H. It is advisable that long-sleeved shirts be worn
when inserting and removing wood or food in-
to/from the oven.
I. Use a non-combustible oven mitt when stoking
and adding wood to the fire, and when inserting
and removing or turning food.
5.2 Tools
Special tools are available for the management of
fireplace and oven fires and inserting and removing
wood and food. These tools can be obtained online,
or from local retailers. Some choices are shown in
Figure 37.
5.3 Selection of Wood
Use cured wood logs only. Scrap wood produces
sparks. Treated wood, coal, or woods dipped in pine

tar should not be used because they may leave a
combustible residue in the fireplace and chimney.
Use of seasoned wood is preferred.
The amount of heat available from logs will depend
on the type of wood, its dryness, quantity of wood
and the size of the logs. Ten pounds of twigs will
produce as much heat as a 10 pound log, but will
produce it much faster because the air supply is more
available.
5.4 Softwood vs. Hardwood
Wood is divided into two classes, hard and soft
woods. Each has a use in a fireplace and each has
advantages and disadvantages.
The hardwood category includes such woods as oak,
walnut, birch, elm and maple. Softwoods include
pine, fir, cedar and spruce.
Selection of wood depends on the type of fire you
want. Softwoods are good to offset a morning chill
because the fire develops faster. Hardwoods are
preferable for a slower burning and uniform heat
output.
Softwoods contain a highly flammable resin that will
leave creosote soot in the chimney flue. This often
results in sparking. Burning softwood exclusively
will require more frequent inspection and cleaning of
the chimney.
Experienced fire builders often use small amounts of
softwood kindling and newspaper when starting a
split hardwood log fire.
5.5 Seasoned Wood
Most freshly cut “green” wood will not burn well
and will smoke. The pressure of moisture and resin
inside green wood will build under heat and explode
as sparks. Therefore, it is recommended that only
seasoned wood be used in your fireplace.
Most wood requires 9 to 12 months of seasoning and
drying to reduce the moisture content enough to pro-
duce good steady fires. Ensure that you buy only
seasoned wood, or if you buy green wood (usually
cheaper), store it properly to aid in the seasoning
process. The following steps will assist in the sea-
soning process.
A. Stack wood loosely to permit maximum air cir-
culation.
B. Do not stack wood on the ground. Use a wood
rack or stack on scrap lumber. Storage on the
ground will cause rotting and insect infiltration.
C. Cover wood stacks with a tarp so that it is not
excessively exposed to the elements such as snow
and rain.
D. Do not stack wood against the walls of your
home.
5.6 Building a Fire
A. Use a log grate (sold separately) with your fire-
place. This will contribute to good air circulation
around the wood, and keep the wood out of the ash.
This grate is shown in Figure 38.
B. Close windows located near the fireplace when
first lighting a fire to reduce the possibility of
smoking. It can be reopened once a draft has been
created through the chimney.
WARNING: NEVER USE GASOLINE,
GASOLINE-TYPE LANTERN
FUEL, KEROSENE,
CHARCOAL LIGHTER FLUID
OR SIMILAR LIQUIDS TO
START OR “FRESHEN UP” A
FIRE IN THE FIREPLACE.
KEEP ALL SUCH LIQUIDS
WELL AWAY FROM THE
FIREPLACE WHILE IT IS IN
USE.
C. Do not overload the wood grate with wood.
Three to four logs on the fire at one time are suffi-
cient. Too much wood on the fire at one time can
result in “over firing,” and too much heat in the
firebox, causing damage to the fireplace.
D. When lighting a fire in a cold chimney, a
downdraft may be created, letting a little smoke
into the room. To correct this, hold a wadded
newspaper in the firebox and light it. This will cre-
ate an updraft and clear the flue of cold air.
The following steps are recommended when starting
a fire.
Figure 38. Log Grate

14
A. Remove any excess ash from the fireplace.
Excessive ash may reduce airflow. Some owners
prefer to leave a small layer to insulate the cold re-
fractory brick below the grate, helping fire starting.
B. Open and close the damper to ensure it operates
properly. Leave it in the full open position when
starting a fire and while the fire is burning.
C. Center the grate over the bottom hearth of the
firebox.
D. Crumble several newspapers across the fire
area underneath the grate. Criss-cross kindling
wood on top of the grate, above the newspaper.
E. Lay three logs on the grate; two side by side
and the third in pyramid fashion on top. Split logs
will start faster. Ensure there is space between the
logs for air circulation. As the air is heated, it is
drawn upwards through the space between the logs,
creating more combustion.
F. Light the paper at both sides of the firebox.
Caution: The fireplace requires air for operation.
Ensure there is sufficient air so that other
fuel burning appliances are not starved of
combustion, ventilation, and dilution air.
G. Set the screen in front of the firebox to prevent
the escape of sparks and embers.
H. Ensure the fire remains centered in the firebox.
Don’t let it move to the front part. Move it back
with the poker.
I. Add wood to the fire as necessary.
CAUTION: Be extremely careful when adding
wood to the fire. Use proper fireplace
tools and wear gloves. If adding an un-
split log, it is possible that it may want to
roll out.
5.7 Cooking
If the oven has been exposed to moisture 48 hours
prior to use, build a small fire and heat the oven to
250-300°F for two hours before increasing the heat
to cooking temperature. An easy solution is to burn
an 8-10 pound bag of match lite charcoal and let it
burn completely. This will slowly dry out the mois-
ture that the oven has absorbed.
As stated, we recommend cooking in a temperature
range of 350° to 600°F. Time of cooking will depend
on the temperature and the item being cooked. The
floor is the heat source that will do most of the cook-
ing. An infra-red temperature gauge like that shown
in Figure 18 can be used to measure temperature at
any location in and around the oven.
Cooking in a wood-fired oven is somewhat like grill-
ing or smoking meats in that there are many varia-
bles such as the type of wood used, ambient
temperature and humidity, oven temperature and
thickness of crust and toppings, that affect the out-
come, Be prepared to spend a few times testing reci-
pes and techniques while learning the nature of
cooking on your Caminetto. Practice and experimen-
tation will show how to best cook your favorite
foods.
Tips for cooking Pizzas :
• A traditional Italian pizza with a thick crust
and a thin layer of toppings should cook at
600°F or hotter for 3-6 minutes.
• For thicker pizzas with heavier toppings,
lower temperatures are required to thorough-
ly cook without burning.
• A medium pizza with heavy toppings may
cook best at 400°F-500°F and will require a
longer cooking times, perhaps 15-25
minutes.
Cook the pizza directly on the floor of the oven.
Place it in the oven using a long-handled paddle
called a peel, using hot mitts or hot pads. Slide the
pizza from the preparation surface to the peel, and
then onto the cooking surface using a slight jerking
technique.
WARNING: Be mindful of the hot surfaces of
your Caminetto oven. Because of
the high temperatures, extra cau-
tion should be used when cooking
with a wood-fired oven. Use prop-
er, long-handled tools and protec-
tive mitts when working around
the opening or reaching into the
hot oven.
6.0 Cleaning, Inspection and
Maintenance
As is the case with most other equipment, cleanliness
is the best maintenance practice and will contribute
too many hours of warmth and pleasure.
WARNING: DO NOT CLEAN THE FIRE-
PLACE WHEN IT IS HOT.

A. Creosote – Formation and Removal. When
wood is burned slowly, it produces tar and other
organic vapors, which combine with expelled mois-
ture to form creosote. The creosote vapors con-
dense in the relatively cool chimney flue of a slow
burning fire. As a result, creosote residue accumu-
lates on the flue lining. When ignited, this creosote
makes an extremely hot fire. The chimney shall be
inspected at least twice a year during the heating
season to determine when a creosote buildup has
occurred. If a significant layer of creosote has ac-
cumulated (3 mm or more), it should be removed to
reduce the risk of a chimney fire.
B. Disposal of ashes - Ashes should be placed in a
metal container with a tight-fitting lid, and taken
outside and placed on the ground, well away from
all combustible materials, pending final disposal. If
the ashes are disposed of by burial in soil or other-
wise locally dispersed, they should be retained in
the closed container until all cinders have thorough-
ly cooled.
C. The grate may be removed from the firebox for
cleaning. However, ensure it is returned prior to
laying the next fire.
D. Keep the fireplace screen clean so air flows
freely through it.
E. Spot check the refractory bricks and mortar for
small cracks. It will expand slightly with the heat,
and then contract as it cools. Replace refractory
bricks when the cracks open more than ¼”; or when
pits become extensive and deeper than 3/16”; or
when any piece of refractory larger than 2 inches in
diameter becomes dislodged.
F. If creosote has accumulated, it should be re-
moved to reduce the risk of a chimney fire. Clean
the chimney as outlined below or have the chimney
cleaned by a professional chimney sweep.
WARNING: DO NOT USE CHEMICAL
CHIMNEY CLEANERS THAT
ARE POURED ON A HOT FIRE.
THE CHEMICAL CLEANER
CAN BE DANGEROUS AND
GENERALLY WILL ONLY
WORK ON THE FLUE
SECTION NEAREST THE FIRE,
LEAVING THE REST OF THE
FLUE UNAFFECTED.
G. Inspect the top cap and opening in your chim-
ney top and remove any debris that could clog it. If
possible, birds will often nest there, and it must be
kept clear of nest material.
H. Check the metal flashing and seals around the
chimney. Seal any cracks or loose nail heads to
prevent roof leaks.
I. Cover the firebox opening with a damp sheet
and seal with masking tape to retain soot in the
firebox while cleaning.
J. Inspect the entire flue from the top down for
obstructions. Use a flexible handled cleaning
brush. If the chimney contains offset/return el-
bows, clean from the top down to the offset, then
from the firebox up to the offset.
K. Check the flue from inside the fireplace with
the damper open for obstructions.
L. After completion of cleaning, use a vacuum
cleaner to remove all soot and residue from the
firebox.
