The device is a Blackstone Leggero Pizza Oven, model 2238 (v02), designed for outdoor use. It is a portable gas-powered appliance primarily used for cooking pizzas, but also suitable for other foods like frozen pizzas and cookies.

Function Description

The Blackstone Leggero Pizza Oven is a gas-fired outdoor cooking appliance specifically designed for high-temperature cooking, ideal for pizzas. It features a burner system that heats a pizza stone, which rotates to ensure even cooking. The oven includes a control knob for adjusting the flame and temperature, a thermometer to monitor internal air temperature, and an ignition system for easy startup. The appliance is powered by a 1 lb (453 g) LPG cylinder and can also use an optional AC power supply or AA batteries for the motor that rotates the pizza stone.

Usage Features

Assembly: The manual provides detailed exploded views and step-by-step instructions for assembly, including attaching legs, door shaft, door handle, baffle panel, and installing batteries.
Fuel Connection: Connects to a 1 lb (453 g) LPG cylinder. Instructions emphasize proper connection to the gas regulator and appliance, and leak testing with a soap and water solution.
Ignition: Features a "Thermocouple Sure-Start Ignition" system. Users push and turn the control knob to LOW, holding for 10-20 seconds until the thermocouple heats up and the igniter clicks. The oven door should remain closed during ignition to maintain temperature.
Temperature Control: A control knob allows adjustment of the flame from HIGH to LOW. The built-in thermometer measures air temperature, but an infrared thermometer (not included) is recommended for accurate stone temperature measurement, which is critical for consistent results.
Pizza Stone Rotation: The pizza stone rotates, powered by an electric motor, to ensure even cooking of pizzas. The motor can be powered by an AC cord or four AA batteries.
Preheating: The oven requires preheating on HIGH for 20-25 minutes to reach the desired stone temperature.
Cooking Flexibility: Allows for cooking various foods. Thinner foods require higher temperatures and shorter cooking times, while thicker/denser foods require lower temperatures and longer cooking times.
Safety Warnings: Numerous warnings are provided regarding gas leaks, unattended operation, fire hazards (especially oil/grease fires), electrical shock, proper clearances from combustible materials, and safe storage of LPG cylinders.
Outdoor Use Only: Strictly designed for outdoor use, with specific guidelines for sheltered outdoor areas to ensure proper ventilation.

Maintenance Features

Burner Check and Cleaning: Before each use, burners should be checked for debris or damage. Instructions are provided for cleaning clogged burners and venturi tubes, which can cause fires. A nylon brush is recommended for cleaning the outer surface of the burner, and compressed air for clearing burner tubes.
General Cleaning: The appliance body should be washed with warm soapy water and wiped dry with a non-abrasive cloth. Abrasive pads, Citrisol, abrasive cleaners, or concentrated cleaners should not be used on the appliance to prevent damage.
Pizza Stone Cleaning: The pizza stone can be cleaned by setting the oven to HIGH for 15-20 minutes to burn off residue. Once cooled, the stone can be flipped to use the cleaner side. Soap should not be used on the cooking stone as it can leave a taste in food.
Storage: The appliance must be cool (below 115°F / 45°C) before moving or storing. If stored indoors, the LPG cylinder must be disconnected and removed. Always cover the appliance when stored outdoors.
Leak Testing: Regular leak tests are recommended, especially after any maintenance or if grease drips onto the valve, hose, or regulator. A soap and water solution is used to detect leaks.
Battery Replacement: Instructions for replacing the AA battery for ignition and optional AA batteries for the motor are provided, including warnings against mixing old and new batteries or different battery types.
Troubleshooting Guide: A comprehensive troubleshooting section addresses common issues such as burner ignition failures, gas flow problems (yellow or irregular flames), and flames coming out of the air gate, offering possible causes and solutions.
