We sincerely believe Fontana is the best wood-fired oven on the market. This is why we offer the best-in-class warranty on all of our ovens. There is a two-year warranty against manufacturer defect. There is also a four-year warranty on the dome of the cooking chamber. We stand by the quality & durability of our product, and we will continue to do so after the sale. Should you ever have a problem with your oven within the warranty period, please let us know using our contact page or call us. We will work to resolve any issue(s) that are a result of manufacturing defect. Unfortunately, because of the fragile nature of the stones, we do not offer a warranty on the stones. However, should your oven arrive with a damaged stone, please contact us immediately. The warranty does not cover the following items: • damage as result of shipment or transporting that has not been highlighted in the bill of lading at the time of receiving of the oven • damage as result of negligent unpacking of the oven  • damage as result of the oven being improperly assembled or installed • damage as result of heating the oven beyond its max temperature rating  • damage as result of using combustible material other than wood to light fires in the oven • damage or corrosion as result of exposure to the elements and/or chemicals • damage that results in a broken or stuck chamber thermometer
