INSTRUCTIONS FOR LIFTING AND MOVING OVEN
ATTENTION:Only proper heavy lifting
machinery and handling equipment should be
used for unloading, moving and installing the
oven. This duty should be performed by
professionals trained in this kind of work.
Improper handling of the equipment could
result in damaging the oven or personal injury.
1- USING A FORKLIFT
Determine if forklift capacity is sufficient to lift
oven. (7,000 lb for 90-Due, 10,000 lb for
model 110-Due’, and 12,000 lb for models
130-Due’)
Prior to lifting, make sure forks are long enough
to reach both horizontal steel tubes on
underside of oven (Without touching oven
shell). Approach oven from front entrance side
or rear side. Keep forklift straight. Carefully
place forks through inside of tube steel
supports legs and position under horizontal
tube steel members. Slowly lift and move oven
as needed. (See dia. A)
2- USING A PALLET JACK
Determine if pallet jack capacity is sufficient to
lift oven. (6000 lb for 110-Due’ and 130-Due’)
Prior to lifting, make sure pallet jack is long
enough to reach both horizontal angles at lower
end of steel tube support legs. Place pallet
jack between tube steel support legs under
horizontal angles. (See dia. B) Carefully lift
oven and move slowly.
CAUTION: OVEN IS TOP HEAVY
MOVE WITH CARE.
3- INSTALLING OVEN
Slowly lower oven into proper location. Oven
should be set on a level floor. Shim as
necessary to assure that oven is level.

PRE-ASSEMBLED INSTALLATION INSTRUCTION GUIDE
READ ALL INSTRUCTIONS CAREFULLY BEFORE INSTALLING AND USING THE APPLIANCE.
If this oven is not properly installed, a fire may result. To reduce the risk of fire, follow the installation
instructions. Please read this entire manual before you install the oven. Failure to follow instructions
may result in property damage, bodily injury, or even death.
The installer should contact the local building or fire officials concerning any installation restrictions and
the need for inspection(s) of the oven and venting applications before beginning installation.
Obtain the necessary permit to construct. In most areas this will include a permit to construct the oven
and a permit for the exhaust system. Sometimes an electrical permit is also necessary for connecting
the exhaust fan. All construction must comply with local building codes. There are some portions of
these instructions which are more restrictive than the building codes. Whichever is most restrictive must
be followed.
The diagram below indicates the minimum floor space required.

IMPORTANT REMINDER
After reading this installation guide it is important to determine which venting application method will be
used.
Most cities accept the U.L. listed chimney installation (direct venting) however a few cities will require the
use of a Type I grease hood over the oven opening. Check with your local building department to
determine which is acceptable.
To maintain the listing of the oven the venting application needs to be installed in accordance with the
guidelines specified in this installation instruction guide.

WARNING:
READ ALL INSTRUCTIONS CAREFULLY. IMPROPER USE OF THIS APPLIANCE MAY RESULT IN A
BUILDING FIRE OR PERSONAL INJURY. INSTRUCTIONS MUST BE READ AND THOROUGHLY
UNDERSTOOD BY ALL OPERATING AND SUPERVISING PERSONNEL. WATCH TRAINING VIDEO
FOR VISUAL OPERATION INSTRUCTIONS.
THIS OVEN IS INTENDED FOR ATTENDED OPERATION BY TRAINED AND QUALIFIED
PERSONNEL ONLY.
THIS OVEN IS A HEAT PRODUCING APPLIANCE AND MAY CAUSE SEVERE BURNS IF TOUCHED.
DO NOT OVERFIRE. IF FLAME SPILLS FROM THE DOOR OPENING OR OVEN TEMPERATURE
EXCEEDS 1000 DEGREES FAHRENHEIT, YOU ARE OVERFIRING.
THIS UNIT IS DESIGNED AS A WOOD-FIRED OVEN. DIRECT FOOD CONTACT WITH HEARTH IS
RESTRICTED TO PIZZA AND BREAD PRODUCTS ONLY. FOR OTHER FOODS REFER TO
MANUFACTURE.
KEEP A PROPER FIRE EXTINGUISHER CLOSE TO THE OVEN AT ALL TIMES. EXTINGUISHER
MUST BE RATED FOR USE ON WOOD FIRES. INSTRUCT ALL PERSONNEL ABOUT LOCATION
AND USE OF THE FIRE EXTINGUISHER AND PROPER FIRE EMERGENCY PROCEDURES.
1. The first six fires should be small in order to properly cure the masonry in the unit. One fire each day for
one hour, for a total of two days (see gas fire instructions for curing gas models). DO NOT USE
PRODUCTS NOT SPECIFIED FOR USE WITH THIS OVEN. Maintain a minimum clearance of 36
inches in front of oven to combustible materials.
2. In case of out of control fire close door tightly.
CAUTION--AVOID POSSIBLE HAZARDOUS FLARE-UPS AND SMOKE SPILLAGE. WHEN
REMOVING DOOR FROM IN FRONT OF DOOR OPENING, SLIDE DOOR OUT 2-3 INCHES FROM
OPENING AND THEN WAIT 15 SECONDS BEFORE REMOVING DOOR COMPLETELY. FLARE-UPS
CAN OCCUR WHEN DOOR IS OPENED SUDDENLY. KEEP FACE AND HANDS AWAY FROM
DOOR OPENING.
3. Burn only seasoned or dried untreated solid wood fuel in the oven. DO NOT BURN OTHER FUELS IN
THE OVEN. DO NOT BURN CHARCOALS, COALS, TRASH/GARBAGE OR MANUFACTURED
LOGS (PROCESSED SOLID FUEL).
4. Firewood stored in the vicinity of the oven must be kept in a tightly-closed metal container; see
maintenance Instructions and NFPA 96. Keep firewood container closed at all times when not adding or
removing firewood. Keep container a considerable distance from the oven and far away from sources of
heat or ignition. DO NOT store matches, paper or other easily ignited items with firewood.
5. Provisions must be made to supply sufficient combustion air into the structure when using this appliance.
Combustion air must be supplied in accordance with local codes and the Uniform Mechanical Code and
NFPA 96.. Exhaust hood and make-up air blowers must be "ON" at all times during firing of the oven. If
the exhaust hood power ventilator fails, close oven door to extinguish the fire and prevent temperature
buildup in the hood duct which can activate the emergency fire suppression system.
6. Use only non-combustible hearth tools and cooking implements inside the oven. Store implements well
away from all combustible materials in a proper fixture which will capture any ashes or hot coals which
may be carried out of the oven on the implements.

EARTHSTONE OVENS PRE-ASSEMBLED INSTALLATION INSTRUCTIONS--- 11
7. The fire should be built directly on the hearth; DO NOT elevate fire.
FIRING OVEN- NOTE: OVEN DOOR SHOULD BE REMOVED WHEN FIRING THE OVEN.
8. a- Before starting, turn "ON" exhaust fan and make-up air blowers.
b- Place a small amount of wood and kindling on the hearth over a fire-starter block. Light fire-
starter. At any time do not use more than four pieces of wood,
c- CAUTION: NEVER USE GASOLINE TYPE LANTERN FUEL, KEROSENE, CHARCOAL
LIGHTER FLUID OR SIMILAR PRODUCTS TO START OR "FRESHEN UP" A FIRE IN THIS
OVEN. KEEP ALL SUCH LIQUIDS WELL AWAY FROM THE OVEN WHEN IN USE.
d. When the kindling is burning well, add larger pieces of firewood. USE WELL-SEASONED OR
DRIEDWOOD ONLY. (Oak, Almond, Walnut, Cherry, Apple and other fruit woods are good)
e- Continue to add fuel as needed to maintain the desired heated rate, being careful to never
overfire the unit.
f- Whenever fuel is added, the fire may be poked and stirred with a wood handling tool. This will
allow air to move through the fuel bed for proper combustion.
g- When oven is heated to cooking temperature, move wood and ash to the rear and sides of the
oven to clear the hearth for cooking product. Insert ash barrier in front of burning wood. This is
to separate the cooking area from the ash and wood. Clean cooking area as described in the
DISPOSAL OF ASHES section before commencing cooking procedures. Food must be placed
on an appropriate cooking pan before being set into the oven.
h- When finished cooking, spread remaining embers on the floor of the oven hearth. Close door
against door opening. This will clean the oven floor.
9. CAUTION: Many structure fires have resulted when a fire has been left unattended for an extended
period of time such as when "Banking" a fire for a long overnight burn. This oven is intended for
attended operation only. Trained personnel must attend and closely supervise the oven at all times
during firing.
DO NOT LEAVE AN UNATTENDED FIRE IN THE OVEN. CLOSE DOOR TIGHTLY AND WAIT UNTIL
FIRE IS EXTINGUISHED BEFORE LEAVING UNIT UNATTENDED.
10. Always keep the area around the unit clear of combustible objects.
11. Read Maintenance Instructions.
12. File these instructions for future reference.
MAINTENANCE INSTRUCTIONS
WARNING:
READ ALL INSTRUCTIONS CAREFULLY. IMPROPER USE OR MAINTENANCE OF THIS
APPLIANCE MAY RESULT IN A BUILDING FIRE OR PERSONAL INJURY.
1. Always keep area around the unit clean and clear of all combustible materials. Keep all furnishings, fuel
and other combustible objects a considerable distance away from the oven hearth.
2. DISPOSAL OF ASHES—Ashes from Ash Pan should be placed in a metal container with a tight-fitting
lid. The closed container should be placed on a non-combustible floor or on the ground, well away from
all combustible materials, pending final disposal. If the ashes are disposed by the burial in soil or

EARTHSTONE OVENS PRE-ASSEMBLED INSTALLATION INSTRUCTIONS--- 12
otherwise locally dispersed, they should be retained in the closed container until all cinders have
thoroughly cooled. After ashes have been removed mop down hearth with clean damp cloths.
3. Store wood in a cool, dry place well away from any source of flame or heat. If stored outside, keep the
fuel covered to protect from rain or snow. If stored inside, fuel should be kept in a covered metal
container at least 6 inches above the floor. Keep paper, rags and other easily ignited materials away
from wood fuel. Refer to NFPA 96 for wood storage procedures.
4. At least at the end of each shift the area around the unit must be thoroughly cleaned of all wood, wood
shavings, embers, ashes and other refuse. All mats (if present, mats must be non-combustible) must be
picked up and carefully swept along with the floor during this clean up. After clean up around the unit,
brooms should be thoroughly wet down to extinguish hot coals, then stored well away from combustible
materials.
5. Creosote - Formation and need for removal
When wood is burned slowly, it produces tar and other organic vapors, which combine with expelled
moisture to form creosote. The creosote vapors condense in the relatively cool oven flue and exhaust
hood of duct, particularly a slow burning fire. As a result, creosote residue accumulates on the flue lining
and exhaust hood. When ignited, this creosote makes an extremely hot fire.
The oven flue, exhaust duct and power ventilator should be inspected at least twice monthly during
normal use to determine if creosote buildup has occurred. If creosote and/or grease has accumulated, it
should be removed to reduce the risk of fire. Experienced chimney and duct servicing personnel who
are qualified in the removal of both creosote and grease from flues and ducts should be contracted to do
the inspection and cleaning. The inspection and cleaning schedule must be adjusted as needed to
prevent the buildup of creosote and/or grease. More frequent inspections and cleanings are indicated
when excessive buildup occurs between regular inspections. The rate of accumulation can increase
whenever 1) there is a change in the use of the oven 2) when the type or moisture content of the
firewood changes 3) when other variables change.
The oven, exhaust hood and grease filters should be cleaned on a daily basis. The Grease filters can be
removed and cleaned in a dishwasher or sink. Refer to the NFPA 96 requirements and the Exhaust
Hood or Grease Duct manufacturer's instructions for inspection, maintenance and cleaning of the venting
system.
DO NOT CLEAN UNIT, HOOD OR VENT WHILE HOT OR WHILE OVEN IS BEING FIRED.
6. The entire unit and vent system should be inspected frequently for proper fit, operation and soundness of
parts. If any malfunctioning parts, leakage, deterioration, or other problems are noted, contact your
dealer to inspect and repair the unit, or qualified ventilation repair service to inspect and repair the vent
system. DO NOT OPERATE THE UNIT IF INSTALLED OR FUNCTIONING IMPROPERLY.
7. All maintenance must be performed by qualified personnel.
8. Refer to NFPA 96 for procedures for inspection, cleaning and maintenance for solid fuel cooking.

Air flow
Installing a sealed enclosure around the oven
shell may cause improper operation by
starving the burner system of combustion air.
The air flow which travels above will cause
“negative pressure” below where the gas
burner is located. The air underneath will travel
towards the air flow above creating a suction
which will force the gas flame downwards. To
prevent this a non-combustable lid must be
placedabovetheoven.
3) Altered airflow from air intake in a separate room with low pressure.

Air flow to oven is altered as air
moves from normal to low

Low pressure is created
by HVAC or any air moving
equipment outside oven

In this case the air intake located on the rear of the oven should be closed.
