Warranty, Cleaning and Care of your Pizza Oven

This Pizza Oven Warranty applies to the Jalando branded range only.

We provide a 1 (one) year materials defects warranty on defects in materials and workmanship for a period of 12 months from the date of delivery as long as the curing and caring guidelines are adhered to.

QUALIFICATIONS TO THE WARRANTY – The complete Product Warranty outlined below does not apply under the following circumstances:

1. The pizza oven has been subjected to non-standard use, such as burning fuels with abnormal burning characteristics including but not limited to; driftwood, charcoal, plywood and wood ovens using a binder that may burn at excessive temperatures and cause damage to the Oven.
2. If your oven is left uncovered and out in the weather elements.
3. To normal wear and tear.
4. To any cracking caused by over-firing or the failure to follow a proper curing schedule.
5. On parts that would be normally worn or replaced under normal conditions.
6. To normal cracking due to expansion and contraction stress relief in the dome, brickwork, precast flue gallery or floor tiles.
7. If the following curing and caring guidelines have not been adhered to.

Caring for your Pizza Oven

Curing the pizza oven – Your oven is made from heat-resistant clay and refractory materials, but the water used to form the clay must be cooked out before your oven can be used. This process is called ‘Curing’. You achieve this by lighting a small fire in your oven 3 – 5 times over a period of 3 – 5 days for about 4-5 hours each time. The curing time depends on whether you have purchased a Jalando DIY kit or a Preassembled pizza oven (please refer to the Jalando Curing Guide you received with your pizza oven for detailed instructions). Please note your floor bricks may sit unevenly until you have used your oven se ve ral times and the insulation blanket has settled.

Protecting the pizza oven – If your oven is not under a covered structure, it must be covered with a tarp or Jalando Pizza Oven cover to prevent water from entering your oven and to protect it from the elements. This will prolong the life of your oven.

Another tip is to waterproof your pizza oven – You may choose to waterproof your oven with a concrete sealer such as, Bondall Natural Finish Sealer or Crommelins Natural Diamond coat paving and Concrete Sealer or Dunlop premium natural look sealer. You would apply this sealer to the external render after the curing process is complete. We also stock acrylic roll-on render in a range of colours which when applied will further waterproof your oven.

Keeping the door slightly ajar will also allow any buildup of moisture to evaporate.

Overloading with wood – Remember it is a pizza oven and not a heater and overheating and overloading with wood can damage the interior of your oven and cause excessive cracking. It can also cause the powder coating on the oven door and/or flue to blister.

Cleaning the pizza oven – Once you have finished cooking clean your oven floor by raking the remainder of the fire across the floor to the front of the oven and leave the door off overnight. You can clean the oven floor with a damp tea towel or a string mop.

The next morning, push back the coals and ensure the oven floor is clean of any food residue. It is recommended that you use your Jalando Pizza oven rake, shovel and brush to complete the cleaning process.

Keep the door on after cleaning and when not in use.

Uneven Floor Bricks

Your firebrick floor tiles are sitting on an insulating blanket and it is not uncommon for the surface not to be completely flat.

They may self correct as you cook:

• Very small high spots (≈ 0.5–1 mm) – As you cook, the tiles settle slightly and the blanket relaxes as ash may fill the gaps between the tiles. (Although small gaps are necessary to allow expansion and contraction of the tiles as they heat up and cool down)
• Minor rocking – Heat cycles let the tiles find a more stable seat.

Steps to fix an uneven floor:

1. 1. Lift out the affected floor bricks.
   2. Re-level the base – Smooth or flatten the insulation bedding layer or remove excess material from high spots.
   3. Relay the bricks tightly together – Use a straight edge or spirit level across multiple bricks and ensure brick tops are perfectly flush.
   4. Dry-lay only – Do not mortar between floor bricks as bricks need to be free to expand.

Oven Cracks

Hairline cracks – Hairline cracks in your refractory pizza oven are completely normal. These cracks often appear between the flue and arch and around the arch, they may also appear on the outer and inner dome of the oven and are a part of the oven’s natural curing process. Your pizza oven is made from refractory materials which are designed to withstand high temperatures but when heated, it expands, and when it cools, it contracts. This expansion and contraction creates small stresses, which often appear as hairline cracks on both the outer and inner surfaces. These cracks are fine and will not penetrate deep enough to compromise the structural integrity or heat retention. The high temperatures that your wood-fired pizza oven reaches (up to 450 degrees c) will create small natural cracks and dilatations on the interior and exterior of your refractory clay oven. This is a completely normal and natural process due to thermal dilatation and will not affect the normalfunctioning of your Pizza oven. These generally occur during the settling-in stage when some expansion occurs and are not structural defects.

Can I fix the cracks that appear in my oven? – If you would like to repair the cracks that appear in your oven you can use Selleys 401 Industrial grade silicone, but you must only use this externally, around the base of the flue or on the cracks. This will be clear in colour, but you can also paint the exterior with paint or our acrylic Roll-on Render. 

These cracks are purely cosmetic, but if you do want to cover them over time, you can choose to apply one of the following to your entire oven exterior, once your oven is cured:

• Apply roll-on acrylic render paint/coating.
• Apply a sealer such as Boncrete –To apply, mix 1-part Bondcrete to 4 parts water and paint this on the surface of the oven, filling in the cracks and joins. If you have any larger hairline cracks you can fill these in with undiluted Bondcrete. This mix will look milky when it is first applied, but it will dry clear.

These will smooth fine cracks and further waterproof your oven. This should only be applied after curing and cooking in your oven a few times.The acrylic render will expand and shrink with your oven due to the elasticity of this product and therefore will minimize the appearance of cracks if applied to your oven any time after the initial curing process. (Please follow the application instructions on the product).

What may cause my floor tile to crack – A small crack in the floor brick will not affect the cooking performance and may occur over time from normal wear and tear. High temperatures can cause pressed bricks to fail. It is important to heat your pizza oven slowly by placing wood in gradually, rather than putting too much in at once, piling too much wood in at once.

Here are the most common causes – 

1. If you heat it up too quickly you may cause thermal shock which will result in cracked floor tiles.
2. Overheating an uncured oven can cause thermal shock or cracks in the clay and should be avoided. It is important that you follow the “Curing your Oven Instructions” that we have provided to you.
3. Moisture in the bricks from rain, cleaning or poor curing
4. Impact of stress, dropping heavy tools, wood logs or pizza peels on the floor.

Prevention Tips:

• Heat the oven gradually during initial and regular firings.
• Ensure proper curing of the oven (drive out all moisture slowly).
• Avoid spilling water or wet materials on hot surfaces.
