shell - IIII , and top plug - 5 ), the oven mouth cover - 6 , a rock wool & wire mesh thermal blanket -
7 , and this Assembly and Operation Manual.
IMPORTANT! Safety always comes first!
Before unpacking the kit, please take notice:
✔ Read this manual thoroughly and keep it for future reference.
✔ This is a very heavy product, with a total weight of 730 lbs / 331 kg ! Always exert good
judgment and correct posture before attempting to lift or move the parts. If a part falls on
you or someone else it may cause serious injury, and mishandling may cause back
injury. Do not handle the parts all by yourself, always use a strong helping hand.
✔ Be careful when handling the rock wool thermal blanket. Rock wool can irritate the eyes, the
skin and the respiratory tract. Use of protection goggles, a respirator and gloves is
mandatory. While the thermal blanket is not used it should be stored inside a sealed bag
and kept away from children and pets.
✔ Last but not least, do not allow children and pets near the oven during assembly and
finishing, as well as during operation.

On to the assembly!
Before starting the assembly, please be sure to comply with the building codes in your area!
The first step is building or preparing a base for the kit to rest upon. The base should be able
to support at least 1100 lbs / 660 kg , a recommended 50% or more safety factor over the oven
weight of 730 lbs / 331 kg . The base must be perfectly flat and level. When planning the base,
don't forget to leave enough clearance around the oven kit for erecting the future oven walls or
any other enclosing and finishing method of your preference, including the mandatory air spaces
for insulation. In our website (www.cuoreovens.com) you will find instructions and tips for building
a suitable base, if needed, as well as suitable enclosures.
After the base is ready ( A ), lay a thin sand bed over the base to help leveling the bottom
plates. Position the left and right ( 137 lbs / 62 kg each) bottom plates ( B ). The flat area corre-
sponds to the front of the oven. The shell pieces are numbered in order of assembly, so place the
oven mouth ( 113 lbs / 51 kg , marked as “ I ”) first over the groove at the bottom plates. Align the
mouth front 1
9/16
” / 4 cm behind the front of the bottom plates. Proceed sequentially with the
remaining shell parts ( 113 lbs / 51 kg each) marked “ II ” (side), “ III ” (side) and “ IIII ” (back),
taking care to fit the edges properly ( C , D , E , F ). You may need to adjust the parts slightly so the
completed shell is centered over the base plates and resting on its grooves. Finally, place the top
plug in the hole on top of the shell ( G ). You may also use the plug in the front hole if you prefer the
chimney to exit from the top hole, but using the front hole for the chimney is strongly advised for
much better thermal performance.
In our website (www.cuoreovens.com) and our FB page (www.facebook.com/cuoreovens) you
will find an animation showing the assembly sequence.
Do not use mortar to glue the parts together, as they should be able to expand and contract
freely during use. However, it is important to seal all the gaps between the parts (on the outside
only) with a 2” wide by 1/2” high strip of high temperature mortar so as to avoid any heat escaping
or debris falling inside the oven during cooking. Do not get mortar between the parts.
After all is set, it is time to unpack the rock wool blanket and fully cover the oven shell (except
for the mouth, naturally) on the outside with it. This blanket serves to conserve heat and to allow
for expansion and contraction of the oven parts independently of the outer walls, thus minimizing
the chances of cracks and fissures. You may cut the blanket as needed, but be sure to use all of it
and allow a good overlap between the pieces, so no part of the shell is left uncovered. You may
find it easier to keep in place by tying it with some thin wire. Again, always use adequate protec-
tion for handling the rock wool.
The chimney.
The chimney is not included in this kit because it will depend on your particular project - long
or short, straight or bent. It can be made of many different materials, from steel tubes to ceramic
pipes or masonry. If you use steel tubes, place a conical flange around the tube at the point where
it exits the oven, so as to avoid debris falling inside the oven trough the gap. You should always
install a flue damper to help regulate airflow and temperature. The chimney should be exclusive to
the oven (avoid sharing the outlet with other appliances) and as straight as possible for better
ventilation. A chimney cap is also mandatory, for water should never get inside the oven. There are
also excellent modular chimney solutions on the market, ask your dealer or contractor for informa-
tion and suggestions. It's also a good idea to install a thermometer near the chimney's inlet for
better temperature control - between 300 °F and 750 °F ( 150 °C and 400 °C ) - during operation,
but you may prefer an infrared thermometer instead. Before installing the chimney, be sure it will
comply with your local codes.
Now enclose and finish it!
After all is done, it's time to enclose the oven kit and finish it. There are basically two ways to
do the enclosing and finishing: by building walls around the oven kit or by covering the thermal
blanket itself with cement or mortar, following the shell shape (the wire mesh will hold the cement
or mortar in place) and then finishing it as you prefer - the “igloo” style. Whichever style you
choose, be sure to make the oven completely sealed from the elements, especially water.
Remember, always comply with the building codes in your area!
Walled enclosures.
A walled enclosure is a classic and very beautiful way to finish your oven. Whatever style
you choose, be sure to observe the following safety rules:
1 - Never use any combustible material in the enclosure. Wooden studs, plywood, drywall or
any other combustible materials are expressly forbidden, for they are a sure way to cause a fire.
The safest method is to build masonry walls with completely non-combustible materials such as
cement or ceramic blocks, bricks or stone.
2 - Only completely non-combustible materials should be allowed to touch the oven kit.
Metal studs and concrete boards are also perfectly suitable, but then air spaces between the oven
kit (or any completely non-combustible material that touches it) and the enclosure walls are man-
datory. The minimum spacings should be 1” / 2.5 cm from all sides and 14” / 35.5 cm from the
top. Around the oven mouth, only completely non-combustible materials should be used, covering
a minimum distance of 6” / 15 cm from it. As to the hearth extension around the oven mouth,
keep a minimum of 30” / 76 cm to the sides of the mouth and 36” / 91 cm to the front of the
mouth free from any combustible material. Do not fill the air spaces with any material.
3 - If you keep the wood in a space below the oven, be sure to leave at least 8½” / 21.5 cm
between the bottom of the oven and the top of the wood storage space. A covered container for
the wood is better for avoiding any contact with ember or stray sparks.
Igloo enclosures.
If you opt for a smaller igloo-style enclosure, there are basically two ways of doing it:
1 - You can cover the oven with a layer or two of insulating cement, spreading it directly on
top of the insulation (the wire mesh will hold the cement in place) or on top of a stucco lath layer.
Proceed with a finishing layer of weatherproof stucco.
2 - You can build a rebar frame around the oven kit and cover it with tied stucco lath, then
cover the whole structure in a layer of stucco ½” / 1.3 cm to ¾” / 1.8 cm thick. Follow with anoth-
er layer of weatherproof stucco or paint.
Remember to obey the recommended clearances from all combustible materials as stated
above, as well as your local building codes.
IMPORTANT! This oven should never, under any circumstances, be operated unfinished and/or
without a chimney. Remember, water (by way of thermal shock) is a mortal enemy of wood-fired
ovens. So if your oven is installed outdoors, it should be very well encased and protected from rain
and seeping water. For the same reason, never wash the inside of the oven.
Indoors or outdoors, you can finish your Cuore 1000 Wood-Fired Oven Kit any way you like.

OK, ready to cook?
Almost. Before using your oven for the first time, it must be heat-conditioned.
IMPORTANT! You should wait ten days before lighting the oven for the first time. Although the
oven itself is ready to use from the factory, this period will allow the masonry structure around it
to cure completely. Failure to do so will void the Product Warranty.
Heat conditioning.
The first fire should be slow and gentle. Put around 2 lbs. ( 1 kg ) of common barbecue coal
(never anthracite!) in the center of the oven and ignite it with some gel alcohol or other safe
method. Do not use flammable liquids! Avoid any tall flames touching the oven walls during this
process. Let it burn completely. Wait four hours and repeat this procedure four more times, always
keeping a four-hour interval between the burns. Failure to do so will void the Product Warranty.
IMPORTANT! Read carefully!
✔ The oven interior and the mouth cover will get very hot during operation. Never allow
children or pets near it while it’s hot, and never put your unprotected hands and arms or
any other body part inside during operation. Always use long oven gloves and mitts to
manipulate anything inside the oven and the mouth cover during operation. Failure to do so
may result in serious skin burns.
✔ Never elevate the fire, place the wood always directly on top of the refractory tiles.
✔ Burn only dry firewood for cooking in this oven (except for common barbecue charcoal,
and exclusively during the heat conditioning process). Never use sappy woods (pine or pine
nodes), compressed or chipped wood products, laminated wood or any other combustible
materials.
✔ Do not use this oven for any function other than cooking, like burning garbage.
✔ This oven is for home use ONLY!
✔ Never use any flammable liquids (alcohol, gasoline, lighter fluid, kerosene or similar fluids)
to start or maintain the fire.
✔ Sparks and embers may be ejected from the oven mouth during operation, so take care and
be sure to keep any combustible materials away during operation.
✔ Although this oven’s door is not the sealing type to allow for some air circulation during
operation, avoid closing the door completely while the fire is on. When you open the door,
there will be a surge in available oxygen inside the oven and the flames may quickly
erupt.
✔ Again, never use water or any other liquid to extinguish or control the fire! The oven will
crack due to thermal shock and void the Product Warranty.
✔ When disposing of the ashes after the oven has cooled down, use a small metal shovel.
Place them in a metal container with a thighly fitting lid. After the ashes are completely
cool, dispose of them according to your area regulations.
✔ When not in use, keep the oven door closed to avoid moisture, foreign objects or animals
from getting inside.
Your oven is now ready for cooking!
Cooking with your Cuore oven.
For normal operation, always start the fire gently using 4 or 5 pieces of dry wood (2”x 5” or
similar size is fine) in the center of the oven. Slowly build up the fire and the heat for two hours,
adding wood as necessary, and then spread the embers to one side, allowing room for the food.
Brush the oven floor (always and only with a copper brush, never steel or any fiber or cloth) where
the food will seat. Again, always avoid tall flames against the oven walls before fully heated. The
recommended temperature range for cooking is between 300 °F - 750 °F ( 150 °C - 400 °C ).
Avoid building the fire near the oven mouth and never let the flames escape through it.
The only foods to have direct contact with the oven surface should be doughs, like pizza and
bread. All other foods, like poultry, cakes, meat, etc. should only be cooked in an appropriate
container.
Check our website (www.cuoreovens.com) for delicious recipes and cooking tips and
techniques!
When you are done cooking, let the fire die naturally. Never use water or any liquid to extin-
guish the fire, and – safety first - allow for the oven to cool completely before sweeping the ashes
out.
Remember, excessive fire or extreme temperature swings may damage the oven even after
heat conditioning. However, even during normal operation small fissures may develop over time.
This is absolutely normal. It's not an indication of malfunction and will have no effect on the struc-
ture and operation of the oven.
IMPORTANT! Safety always comes first!
✔ Never use flammable liquids to light the oven! The mixture of air and flammable
liquid vapors inside the oven may cause an explosion.
✔ Keep children away from the oven during operation. The mouth cover will get very
hot and may cause serious burns if touched! Always use the handle!
✔ Do not use the pallet wood as oven fuel. Due to international commerce regulations, it
has been treated with chemicals to avoid pest contamination.
