The Ooni Fyra 12 is an outdoor pizza oven fuelled by hardwood pellets, combining a 33 x 33cm cooking area with a transportable 10kg body. Argos states it reaches around 500°C in about 15 minutes and can cook a 12-inch pizza in approximately 60 seconds once fully heated. Pellet fuel gives this model a different operating method from the propane Koda ovens and the wood or charcoal Karu ovens. A powder-coated steel construction and included ash catcher support outdoor use and cleaning. The listed dimensions are 72 x 39 x 74cm; allow room around the oven and use it only in a suitable outdoor cooking space. For cooking, place the oven on a stable, heat-resistant surface outdoors, with the clearances and ventilation stated in the instructions. Preheat the cooking stone fully, then turn the pizza during cooking so the base and toppings finish evenly. Cooking time depends on the fuel, ambient conditions, dough and toppings rather than a fixed timer. The Fyra uses hardwood pellets fed through its hopper, so it has a different fuel routine from the gas-only Koda models. Keep an appropriate supply of dry pellets available for preheating and for cooking multiple pizzas. The 33cm square stone has room for a 12-inch pizza, which should be turned as needed for an even finish. The ash catcher helps with clean-up after the oven is fully cool. Its listed 10kg weight makes it one of the lighter Ooni models in this selection. Confirm a suitable outdoor position with clearance around the chimney and opening.
