Preheat the Oven: Turn on the gas and set the oven to the desired temperature (usually around 450°F or 230°C). Allow it to preheat for 10-15 minutes.
Prepare Pizzas: While the oven preheats, prepare your pizzas on trays or directly on the oven rack.
Load the Oven: Open the oven door and carefully place up to 18 pizzas (depending on size) onto the oven racks or pizza stones.
Bake the Pizzas: Close the oven door and bake the pizzas for the recommended time (usually 10-15 minutes), depending on the thickness and toppings.
Monitor Cooking: Check the pizzas occasionally to ensure even cooking. Adjust the temperature if needed.
Remove Pizzas: Once done, use oven mitts or a pizza peel to remove the pizzas from the oven.
Turn Off: After use, turn off the gas and clean the oven according to the manufacturer's instructions.
