Im new to gas grill what is the basis. Does vaporizer bar stay on while cooking?

A gas grill operates by burning propane or natural gas to produce heat for cooking food. Here's the basic setup and functionality of a gas grill:

Main Burner:

- This is the primary source of heat in a gas grill. It consists of several burner tubes placed underneath the cooking grate. When the grill is turned on, gas flows through these burner tubes, and igniters (either electric or manual) generate a spark to ignite the gas, producing flames.

Control Knobs:

- Each burner tube has a corresponding control knob on the front panel of the grill. Turning these knobs adjusts the gas flow to the burners, allowing you to control the temperature of the grill.

Vaporizer Bars (Flavorizer Bars):

- These are metal bars or plates located directly above the burners. Their main purpose is to vaporize drippings that fall from the cooking grate and produce flavor-enhancing smoke for your food. Some vaporizer bars are designed to absorb and vaporize marinades and seasonings as well.

Cooking Grate:

- This is where you place your food for cooking. The cooking grate is usually made of cast iron or stainless steel and sits above the vaporizer bars. The heat from the burners below passes through the grates, directly heating the food.

Drip Pan:

- This pan is located at the bottom of the grill, underneath the burners and vaporizer bars. It catches any grease or drippings that fall from the cooking grate during the cooking process, preventing flare-ups and making cleanup easier.

Fuel Source:

- Gas grills are powered either by propane or natural gas. Propane grills come with a refillable propane tank that connects to the grill, while natural gas grills require a direct connection to a natural gas line.

Regarding the vaporizer bar, it generally stays on while you're cooking as it helps vaporize drippings and add flavor to your food. However, some grill models may have a separate control knob for the vaporizer bars, allowing you to turn them on or off as needed.
