Safely Lift the Dome With the Cook Time is Through
Once you're done cooking, lift the dome an inch or two, then lower slightly, then lift slightly. This action is called "burping." Don't open the dome fully until you've done this action. You don't want a rush of oxygen into the flame, otherwise you may risk injury. You can quickly extinguish the fire by shutting the metal top and bottom sliding door completely closed. No air means no fire.
