Other backyard pizza ovens have single burners that cook from either above or below. The problem with this is that pizza is a two-layer food. The crust on bottom, toppings (cheese, sauce, meat and veggies) on top. Heating from just above or below short changes one or the other and makes it more difficult to properly cook each. The result can be either burnt crust or undercooked toppings. Bertello solves this problem with the exclusive “FlameThrower” Dual Burner System, two separate burners that heat the stone from underneath and cook the toppings from above. The premium, full length “Under-The-Stone” burner extends fully from back to front to heat the stone evenly for consistent crust-cooking performance. The second burner, the “Over-The-Toppings” burner resides above the pizza in the back of the oven where it ensures the toppings get properly cooked. Only Bertello offers this FlameThrower Dual Burner System! Note: Cooking pizza is different from grilling a burger or steak on a grill where you can flip the food to cook both sides. You can’t flip a pizza. That’s why we created the FlameThrower Dual (Over-and-Under) Burner system!
