REPLACEMENT PARTS LIST:

HearthStone Outdoor 4.5 Patio Oven
ASSEMBLY
Your HearthStone Outdoor patio oven ships mostly assembled. In the crate you will find the following:
Pt# Description Quantity
5145-0800 Oven Door Assembly 1
5700-180 Chimney Cap 1
5700-750 Flue Pipe 1
4700-1020 Adjustable Oven Feet 4
Wheel Chocks 2
If your order consisted of the oven alone, you need only attach the adjustable feet and set the unit in its final
location. To attach the feet:
1) Remove the shipping crate sides to expose the complete perimeter of the oven.
2) Locate the bag containing the four adjustable Oven Feet and remove the contents.
3) The oven bottom is suspended off of the shipping crate floor by blocks. There should be enough
room to place the legs in position along the outside edges and turn them clockwise into the mounting
holes by hand. If the fit is too snug, gently lift one side of the oven and place a 2”x4” block on its side
on top of the shipping blocks to add clearance. Do this one side at a time to provide adequate
stability. The legs will only thread into one hole near each corner.
4) Remove the oven from the crate by lifting from each side and place into the final installation position.
It is possible to remove the oven floor stone to aid in lifting. Not the order and positioning of the
stones so that they may be reinstalled in the same order when the oven is set in its final position.
**WARNING: DO NOT LIFT BY THE FRONT SILL**
5) Level the stove by turning the feet at the middle until stable.
If your order consisted of the oven and corresponding base, you must first attach the feet as described above
before placing the unit on the base. The base comes fully assembled. Align the posts protruding up from the
base with the corresponding holes in the oven bottom and lower the top onto the base. The legs and the
posts hold the top in place with no further action.

RECOMMENDATIONS FOR USE
Follow these simple steps to get the most out of your HearthStone Outdoor oven.
LIGHTING
1. Make a small pile of wood in the center of the oven with small pieces of dry wood.
2. Ignite the wood with a long stem ignition device to keep hands away from the fire.
3. When the wood is well-lit, add two larger logs and move the fire to one side of the oven.
4. After a few minutes of continuous burning, a temperature of 250°C/482°F will be reached, and a
descent coal bed will be formed. This is the moment the oven is ready to be used.
CAUTION:
The oven should be fed frequently with small cut firewood, at most 18 lbs. /h. Overloading should be avoided
and does not allow good baking results. A small fire is all that is needed to properly operate the appliance.
TURNING OFF
1. To turn the oven off, stop adding fuel and fully close the oven door.
2. Allow the fire to completely burn down to ash.
3. After all active fire has burned down and the coals are not visibly glowing, wait an additional 30
minutes before removing the ashes and placing them in a non-combustible container with a tight fitting
lid.
DIFFERENT TYPES OF WOOD
Use small sized wood pieces that are very dry.
Each wood type provides a fragrance to food in a different way. For example, wood from fruit trees is used
to give food a more appetizing aroma to fish and poultry. Similarly, maple, walnut and chestnut go well for
other foods like red meat and pork.
Treated wood, resin or scrap wood should never be used.
Wet or damp wood can pop due to the increased volume of water. This will produce excess smoke and
less heat.
THERMOMETER
The thermometer detects temperature at a representative point inside the oven. With experience, it will be
easy to assess when the oven is ready for various types of cooking. With practice and experience, you will
become very adept at controlling the cooking temperature.
OVEN DOOR
The door is very effective at adjusting
heat intensity: by closing and opening it
the temperature may be better managed.
If the fire is too high and comes out from
the oven mouth, use the door to adjust
the flame.
In general, the more open the door is the
larger the fire will become.

COOKING
Always preheat the oven before cooking. After ignition, wait for 15 minutes or until the thermometer
reaches 350-400°C / 660-750°F. Once this temperature has been reached, wait a few minutes longer for
the oven temperature to stabilize and ensure that the oven floor warms up properly.
Allow for longer cooking time on cold or windy days and at high altitudes. Shorter cooking times will result
if external temperature is particularly high.
Cooking times vary according to weather conditions or the amount, dimensions and shape of the food to
be cooked.
ADVICE FOR COOKING PIZZA
Allow the oven to warm for around 20 minutes after ignition to reach the optimum temperature for cooking
an excellent Neapolitan pizza (with an increased level of moisture).
Maintain an oven temperature of 400°C/750°F.
Maintain a refractory floor temperature of 350°C/660°F.
Once the optimal temperature is reached, it is sufficient to add a few small sized wooden logs every 3-5
minutes. This will maintain a constant temperature and you can begin inserting the pizzas.
Check that there is no build-up of grease, and, if present, remove to prevent the grease from catching fire.
During cooking do not lean over the open oven and do not place hands or fingers on the front sill.
During cooking, the oven body will be hot; therefore, it should never be moved or left unattended.
MAINTENANCE
Before you turn the unit on ensure the chimney flue is free from any objects and that ash from previous
cooking has been removed.
After cooking, remove the ash when the embers have extinguished.
After the unit has cooled, clean any food residue from the surface.
The oven can be used year round. In the winter, heat the oven with a smaller fire to avoid thermal shock.
Keep the external surfaces of the oven clean to prevent damage.
CLEANING
When the fire has gone out and the oven is no longer warm, collect the ashes left over from cooking with a
metallic brush and a pan.
Clean the oven floor (when the oven is cold) with a brush and gently wipe the oven floor with a damp cloth.
Use a damp cloth to clean the external metal.
Apply a light coat of vaseline to make the metal shine.
Remove and clean the chimney flue once a year. Animals may nest there and/or ash may block the
passage of smoke.
If the oven gets dirty with food residue normal operation will incinerate the residues.
If traces of rust begin to appear, clean with a polishing brush and apply a thin coat of vaseline.

HearthStone Outdoor 4.5 Patio Oven
To sanitize, clean and heat the cooking floor before cooking. Sprinkle the inside of the oven with hot
embers making sure to cover the entire the oven floor and leave for a few minutes.
Do not use chemical products to clean the oven.
Do not clean the product when it is in use.
If the oven is exposed in a sea side, in order to prevent corrosion and fouling it is recommended to
frequently clean the oven with fresh water.
TROUBLESHOOTING
IF THE OVEN PRODUCES SMOKE
Check that the wood is not too moist and the embers are not unburned.
Make sure that you have started a fire with vivid flames, gradual but steady, in order to avoid incomplete
combustion.
Check the chimney flue for blockage or leaks.
Close the oven door.
IF THE OVEN DOES NOT HEAT
Check that the fire is on one side of the oven and not near the mouth.
Burn a fire with vivid flames for at least 20 minutes.
Do not overload unburned wood over the embers.
Gradually add additional wood to the fire.
IF THE OVEN COOLS DOWN QUICKLY
Check that no moisture or water has infiltrated the oven.
Avoid sudden short fires that do not warm the bottom of the oven.
IF THE FLAMES COME OUT OF THE MOUTH OR CHIMNEY CAP
Avoid excessive fires. Immediately dampen the flames by fully closing the door over the mouth of the
oven.
IF THE OVEN DOESN’T COOK AS YOU WOULD LIKE
Ensure the oven is at the right temperature.
Ensure the oven maintains the desired temperature for the duration of the cooking time. Use the door to
adjust the heat intensity. Open and close it to raise or lower the temperature as necessary.
