Ooni Karu 16 FAQ



How do I set up and light my Ooni Karu 16?

To set up your Ooni Karu 16, you’ll need to follow a few simple steps:

1. Unpack your oven, unfold the legs, insert the stone and attach the chimney, fuel tray, and door.

2. Place your oven on an outdoor surface made of stone, metal, or wood that is set up outside. Tables made of glass or plastic are not recommended. Never use your oven indoors. 

3. Allow your oven 3 feet/1 meter of clearance on all sides and 9 feet/3 meters above.

4. Gather your pizza peel, dough and toppings - your oven will be fully preheated in 15 minutes!

If working with solid fuels (wood and/or charcoal):

1. Remove the chimney cap. 

2. Open your chimney baffle, put the door on, and open the fuel hatch.

3. Place a layer of charcoal through the hatch door into the fuel tray. 

4. Add 4-5 pieces of wood. 

5. Ignite the wood/charcoal using either a gas blowtorch or matches and Ooni Premium Natural Firestarters

If working with propane:

1. Remove the fuel tray and grate and connect the burner per manual instructions.

2. Remove the fuel hatch, open the ceiling vents and open the door when igniting your burner. 

3. Connect the regulator and hose to your propane tank *This will either be a push-on fitting or a threaded fitting, depending on you region

4. Open up the gas from your propane tank.

5. Find the control knob on the back of the oven. Push in and slowly turn the control knob counterclockwise until you hear a click and the burner ignites. 

6. Continue to push in the control knob for 5 seconds after ignition, then release.

7. Put the door back on and let your oven heat up.

If working with natural gas:

1. Remove the fuel tray and grate and connect the burner per manual instructions.

2. Remove the fuel hatch, open the ceiling vents and open the door when igniting your burner. 

3. Connect the regulator and hose to your natural gas connection.

4. Open up the gas from your natural gas line.

5. Find the control knob on the back of the oven. Push in and slowly turn the control knob counterclockwise until you hear a click and the burner ignites. 

6. Continue to push in the control knob for 5 seconds after ignition, then release.

7. Put the door back on and let your oven heat up.

*Ooni Karu 16 Gas Burner should run quietly when lit. If you hear a roaring noise from the gas burner, switch the gas off for 5 minutes, then re-light.

When using your oven for the first time, let it run at high temperature (750°F/400°C) for 30 minutes, then cool it down completely to season the oven and ready it for use.

What should I do before I start cooking in my Ooni Karu 16?

Fire your empty Ooni Karu 16 at a high temperature (750°F/400°C) for 30 minutes. Allow it to cool fully and wipe down the inside with a dry paper towel. After this 'seasoning' process, your oven will be ready to cook great pizza.

Where can I use and store my Ooni Karu 16?

Ooni Karu 16 is designed for outdoor use only. Burning propane/butane/LPG or solid fuels indoors can cause carbon monoxide to build up to unsafe levels.

You must also leave 3 feet/1 meter of clearance on all sides of your oven and 9 feet/3 meters of clearance above your oven. This means Ooni Karu 16 will not be suitable for use on most balconies.

When your oven is not in use, use an Ooni Karu 16 Cover to keep it safe from the elements. For occasions where the weather is stronger than usual, such as periods of heavy snow or rain, or extended exposure to sea breeze, bring your oven indoors to protect it

How hot and smoky will my Ooni Karu 16 get?

Your oven will be hot to the touch, so please exercise some caution. The legs of your oven will not transfer this heat, which will keep your wooden, stone or metal surface safe. There are also cool touchpoints on the oven. Handles for the glass door and fuel hatch will stay cool throughout the cooking process.

When cooking with wood and charcoal:

When cooking with gas:

  • You can expect some smoke throughout the cooking process, especially as your oven is near the peak of the heating process. 
  • Once your oven has reached high temperatures, the smoke should lessen.
  • You should not see much smoke when working with propane, butane, LPG or natural gas. These fuels will typically burn very cleanly.


How much fuel will my Ooni Karu 16 use?

Fuel Type


Solid fuels (wood, charcoal)

4.9lb/2.2kg per 10 pizzas

Gas (propane, butane, LPG, natural gas)

1.1lb/0.5kg per hour

What kind of wood and charcoal do I need to use with my Ooni Karu 16?

A combination of both wood and charcoal will give you the best results in Ooni Karu 16. Always use lumpwood charcoal and kiln-dried hardwoods. 

Beech, birch, oak, hickory, mesquite, apple, and cherry are a few readily available hardwoods, but this is not a definitive list.

The photo below shows a good example of the wood size to use in your Ooni Karu 16:

Our Ooni Premium Assorted Hardwood Oak Pack contains wood in all three of these sizes. You can order this here (UK), here (EU), and here (USA).

Does Ooni Karu 16 work with wood pellets?

Ooni Karu 16 is designed to be used with hardwood kindling, lumpwood charcoal or gas. Wood pellets are not suitable for this fuel tray; they will keep your oven from getting up to temperature. 

What kind of gas tank and regulator do I need to use with my Ooni Karu 16 Gas Burner?

Your Ooni Karu 16 Gas Burner will work with a standard propane tank and comes with a regulator. Propane tanks and regulators will vary across regions.

If you are ordering a 30mBar burner, you will need to purchase your own region-specific gas hose and regulator.

Please see the charts below for more information.

Suitable Gas Tanks

Unsuitable Gas Tanks

20lb/6-13kg propane tanks

Propane tanks larger than 30lbs 

Natural gas*

A 30mBar regulator will not come with your gas burner. 

The range of 30mBar regulators is vast, and it is currently best for you to choose the regulator most suitable for use with the gas tanks available to you. 

Region Specific

Belgium, Cyprus, Czech Republic, France, Great Britain, Greece, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Portugal, Slovakia, Slovenia, Spain, Switzerland


“Patio Gas” = propane

*If using propane tanks like the red ones in this photo, please see below for further instructions.

Austria, Germany, Slovakia, Switzerland

50 mBar

If you have a 37mBar oven and you’re using a propane tank that looks like the red tanks in the chart above, you will need to purchase a POL regulator. It will look something like this. Once you have the new regulator, watch this instructional video and follow the instructions below:

1. Loosen the jubilee clips, which look like this:

2. Soften up the edge of the hose by warming it with a hair dryer or dipping the hose in hot water for 10 seconds.

3. Once you have softened the hose, pull the regulator off.

4. Replace the Ooni-provided regulator with the POL regulator.

5. Replace the jubilee clips and tighten them so there’s an airtight seal around the hose and valve.

6. Do a leak test with liquid soap and water: Put some soapy water on the connection points of the hose, turn the gas on and see if any bubbles are created. If you see bubbles, you’ve got a leak. 

  • If there are bubbles, go back in and make sure to tighten the seals around the hose.
  • If there are no bubbles, you’re ready to make some pizza!

Can I use butane and/or natural gas?

Ooni Karu 16 has been certified for use with propane, butane and LPG gas, which is a mix of both. Propane and butane are very similar, but burn slightly differently. Please note that butane will produce a somewhat sootier flame.

  • In the US/CA, we recommend only using propane only. 
  • In the UK and EU, the regulator you’ll need for butane will depend on your oven, as outlined in the chart below.

Oven Type

Butane Regulator Needed

37mBar Ooni Karu 16 Gas Burner

28-30mBar butane-compatible regulator

30mBar Ooni Karu 16 Gas Burner

28-30mBar butane-compatible regulator 

50mBar Ooni Karu 16 Gas Burner

Not certified for use with butane.

Ooni Karu 16 can be used with natural gas after installing the Ooni Karu 16 Natural Gas Burner

What safety devices are installed in Ooni gas-fired products?

Your Ooni Karu 16 Gas Burner includes a Flame Safety Device (FSD). This device ensures your gas burner will not continue releasing gas if the oven temperature suggests there is no flame. This was designed and implemented to make sure your oven is as safe as it is fun. 

If your gas burner appears to cut out when a flame is present, please contact us over at support.ooni.com

What should my flames look like? 

Once ignited, you can expect the color of the flame in your oven to range between yellow and blue. Your flames should look something like those in the below photos:

What should I do if I’m having trouble lighting my Ooni Karu 16 Gas Burner?

First, double check that your Ooni Karu 16 Gas Burner is installed correctly:

1. Assemble and install your gas burner

2. Remove the chimney cap and ensure the chimney baffle, fuel hatch, ceiling vents and door are open during ignition.

3. After ignition, you can add the fuel hatch to the rear, open the ceiling vents, and close the oven door.

Then, walk through the following steps before trying to light your burner again:

1. Ensure that your Ooni Gas Burner is in the "off" position.

2. Disconnect your regulator from the propane tank for 5 minutes.

3. Check that the connections between regulator and bottle are clean and free of debris. 

4. Secure the connections between your regulator, hose and propane tank. Use a leak detector spray to check for any gas leaks.

5. Remove any kinks or bends in the hose.

6. Keep your propane tank upright: If resting on its side, gas will not flow properly.

Other helpful tips: 

  • Use compressed air to remove any debris from the inside of your gas burner. 
  • If you hear a loud roaring sound, switch your gas burner off for 5 minutes.
  • Do not fire your gas burner in high winds.
  • Keep your gas burner stored indoors when not in use.

3. For tougher stains, clean with soapy water and dry immediately. 

How to clean the inside of your oven:

1. Let the oven cool down completely 

2. If you’ve used solid fuels, dispose of cooled ashes in a fire pit, compost pile or any other environmentally-friendly waste disposal option available to you

3. Use a stiff wire brush to clear excess soot from the fuel tray and grate so the perforations are free of debris. This will help with airflow for your next cook. 

4. To clean soot from the pizza door and chimney, use a dry paper towel. Avoid using water to clean the inside of the oven.

How to clean the glass on your door:

1. Wipe down the glass using a dry paper towel to remove the bulk of the soot.

2. Apply a solution of 1 part vinegar, 3 parts water to the glass using a clean rag.
