Full List of the Different Parts of a Gas Grill

If you’re a car person, you know how all the different parts of a car work together to get you where you want to go and create an outstanding driving experience.

Did you know the same goes for gas grills?

There’s a lot more going on under your grill’s hood than just a propane tank and an ignition button. From the powerful burners that sear your steaks to the precision temperature gauges that ensure your food is cooked to perfection, all of these parts operate together to give you complete control over the grilling experience.

In this guide, we’re covering a full list of the different parts of a gas grill, including the burners, igniters, cooking grates, down to the wheels, and the role they play.

We’ll also share which of these parts are the most crucial to keep clean, and when you might want to consider replacing parts instead of replacing the entire grill.

Anatomy of a Gas Grill: A Breakdown of the 3 Core Components

The Hood | The Cooking System | The Grease Management System

We put together this anatomy of a gas grill parts guide to help you identify all the parts in your gas grill. This comes in handy when it’s time to replace a part.

To start, we’ve broken down gas grills into their three main parts: the Hood, the Cooking System, and the Grease Management System.

Every grill can vary in design somewhat, but with this lineup of its major players, you can keep your grill in great shape and working just like it’s supposed to.

Here’s a closer look at each section and the roles they play.

The Hood

The hood covers the grill and helps to retain heat, which you need while cooking. With the hood closed you can control the ambient temperature around the food, mimicking an oven-like environment.

The hood also helps to trap smoke from the burning grease and drippings, allowing it to circulate around the food, which enhances the smoky flavor that is a hallmark of great barbecue.

It’s also there to protect the grill’s internal components when not in use. It helps keep rain, dust, and debris out of the grill.

Hoods come equipped with a handle for opening and closing them. Most also feature a built-in thermometer that lets you monitor the internal temperature.

Many higher-end gas grills come with heavy-duty double-walled hoods for added heat retention, and spring-assisted hoods to make it easier to open and close the heavy lid of the grill. You might also find built-in lights inside the hood on these models.

The Cooking System

At the heart of your gas grill is the Cooking System. The main parts of the cooking system include:

  • The Firebox: This contains all the primary cooking components.
  • Burners: These are the main heat source for the grill.
  • Cooking Grates: The surface where the food is placed to cook.
  • Heat Distribution System: Typically involves heat plates or flame tamers located above the burners to distribute heat evenly and protect the burners from dripping grease.
  • Ignition: The mechanism used to light the grill.

Understanding which part in the cooking system does what job helps you not only get a better understanding of how your grill works but also what parts might need to be replaced when something goes wrong.

The Grease Management System

Proper grease management is there for safe grill operation and to prevent dangerous flare-ups.

The grease management system usually includes a grease tray or cup, and sometimes both. Grease trays and cups are designed to catch drippings and debris from the food you are cooking and funnel it away from the fire. They should be emptied regularly to avoid build-up.

Now that we’ve covered the 3 main parts of a gas grill, we’ll break it down even further. In this section, we’ll cover all of the essential parts of a standard gas grill.

Understanding all of the parts and how they work together to make your grill, well, grill, is an incredibly important but overlooked part of outdoor cooking.

Most often, issues with gas grills will happen with one of these major parts inside of the grill. These essential components are what every grill needs to operate properly.

Here’s a quick rundown of those parts and what they do:

Gas Grill Parts Explained

Firebox/Grill Body

Think of the firebox, or the grill body, as the sturdy heart of your gas grill. It’s usually crafted from tough metals like stainless steel or cast aluminum, which are great at handling heat and fighting off rust.

Inside the firebox, you’ll find the burners, flavorizer bars, and grill grates among others. Mounted at the front, there’s the gas valve manifold—which lets you control the gas flow, allowing for easy adjustments during cooking.

Control Panel

Think of the control panel as the command center of your gas grill. It’s where you control what’s happening inside your grill.

On the control panel, you’ll find the temperature knobs that let you adjust the heat with precision, the ignition system to fire up the grill, and sometimes even a handy temperature gauge.

With a well-designed control panel, you’ll be in total control the entire time you’re using your grill, making for a simplified and enjoyable cooking experience. You get to manage everything from one spot, which means more time enjoying the grilling and less time fussing with settings.

 A Gas Grill Lid Temperature Gauge

Lid and Temperature Gauge

The lid of your gas grill does more than just cover the top; it plays an important role in heat retention to essentially turn your grill into an outdoor oven.

This not only cooks your food more evenly but also helps prevent flare-ups by limiting oxygen flow and keeping the flavorful smoke where you want it—circling around your food.

Many gas grills feature lids that come with a built-in thermometer, which gives you the ability to keep an eye on the grill’s temperature without opening the lid.

Gas Grill Burner Control Knobs

Burner Control Knobs

The burner control knobs on your grill are there for fine-tuning the heat. Typically located on the front panel, these knobs feature intuitive markings—either numbers or symbols—that show the heat level setting. With a simple twist, you can adjust the flame to ensure your grill cooks just the way you want it.

Burner Control Valves

Valves control your grill’s heat distribution by regulating the flow of gas from the tank to the burners. Consider them the unsung heroes of your grilling experience, helping you keep the temperature just right.

The valves are typically located within the control panel area, directly connected to the control knobs. When you adjust a knob, it turns a valve, which controls the flow of gas through the grill’s internal piping system to the burners.

Grill Manifold

The manifold is positioned at the front of your grill and is typically located behind the control panel. It houses the burner control valves and includes the gas tubing that links these valves to the gas tank.

The control panel houses the knobs and controls, and when these are adjusted, they manipulate the valves within the manifold to regulate gas flow to the burners.

So, while the manifold and control panel work closely together, the manifold is more about internal connections and gas flow, and the control panel is the external interface you interact with.

Gas Grill Cooking Grates

Cooking Grates

Cooking grates are where the magic happens—they provide the surface where your food cooks.

Made from materials like stainless steel, porcelain-coated, or cast iron, these grates come in various types of patterns tailored to different grilling needs.

Whether it’s a diamond pattern that increases food-to-surface contact or sturdy hexagonal grates, each design has its pros or cons.

You can read more about which cooking grates we recommend for gas grills in our guide:

A Gas Grill Warming Rack

Warming Rack

The warming rack is the spot where you can keep food warm after it’s finished cooking. This allows you to free up space on the main cooking surface for more grilling.

It’s not just for keeping dishes warm; you can also use it to gently heat hamburger or hotdog buns.

A Gas Grill Ignition System

Igniters

Igniters are what start your grill—they generate the spark that ignites the gas, creating the flames needed for cooking our grill might have one of several types of ignition systems.

Piezo starters, for example, generate a small spark with a simple push or turn and do not require batteries. Other systems might use batteries or an electrical current to ignite the gas.

Gas Grill Flame Tamers and Heat Plates

Barriers/Heat Plates

Also known as heat shields, these barriers are positioned above the burners. and serve multiple purposes.

They protect the burners from fats or marinades that might cause corrosion or flare-ups. They also help distribute heat evenly across the cooking surface, while vaporizing any drippings to enhance your food with flavorful smoke.

Is your gas grill smoking too much? Then we have a guide that can help you:

Gas Grill Is Smoking Too Much? Here’s How to Fix It

Gas Collector Box

The gas collector box houses the ignition system’s electrode and sits at the inlet to the burner tube. Its primary job is to collect any gas that builds up during the ignition process and allow it to flow into unlit burners.

It creates a concentrated spot for the gas to ignite more reliably and safely. It also helps prevent the gas from building up and causing potential flashbacks.

A Gas Grill Burner

Burners and Burner Brackets

Burners are where the action happens in your gas grill, responsible for generating the flames and heat needed to grill your food.

Most grills feature at least two burners, allowing you to control them individually to create different temperature zones. This setup supports more flexible cooking options.

You’ll typically find burners manufactured from stainless steel or cast iron to help facilitate even heat distribution across the cooking surface. The shape of the burners can vary depending on your grill’s model.

Here are the common types of burners that can be found in gas grills:

  • Tube Burners: These are long, straight burners usually made of stainless steel or aluminized steel. They’re common in many basic and mid-range grills.
  • Cast Iron Burners: Known for their durability and heat retention, cast iron burners are heavier and may require more maintenance to prevent rust, but they provide consistent heat.
  • Infrared Burners: These burners use infrared technology to cook food, offering high temperatures that are great for searing meats quickly while locking in juices.
  • Double-Sided Burners: Offering two sides that can be controlled independently, these burners allow for versatile cooking options, enabling you to cook at different temperatures on the same burner.
  • H-Shaped Burners: Named for their shape, these burners provide more even heat distribution and are typically found in larger grills.
  • Figure 8 or Infinity Burners: These burners have a figure-eight shape that provides even more heat coverage than H-shaped burners, which is perfect for grilling larger quantities of food evenly.

Burner brackets are the parts that hold the main burners in place, providing stability and safety as you cook.

Gas Grill Venturi Tubes

Venturi Tubes

Venturi tubes are typically located beneath the grill’s control panel, connecting directly to the burners. They extend from the gas valves to the burners and are responsible for mixing air with the gas before it is ignited.

They help control the flow of fuel efficiently. Once this mix reaches the burners, it’s ignited to create the flame needed for cooking.

You can learn more about how the gas and air are mixed to produce the perfect gas grill flames and how to adjust it if needed in our guide below:

How to Adjust a Grill Air Shutter on Your Gas Burners

Gas Grill Burner Carryover Tube

Carryover Tubes

Carryover tubes link together and the burners together, allowing the flame to travel between them when lighting the grill. This feature is particularly useful when lighting the grill, as it makes sure that multiple burners ignite smoothly and simultaneously.

Not all gas grills use carryover tubes. While many traditional and popular models feature carryover tubes to help spread the flame across burners for easier and more reliable ignition, some modern gas grills use alternative methods.

These might include individual ignition systems for each burner, which don’t require the flame to be physically carried over from one burner to another. This can often be found in higher-end models where each burner can be controlled and lit independently.

A Gas Grill Pressure Regulator and Grill Hose

Pressure Regulator and Grill Hose

The pressure regulator is a safety feature on the grill that helps regulate the flow of gas and prevent gas-related accidents. It is located at the point where the gas tank connects to your grill by the grill hose.

It helps manage the flow of gas, providing a steady, controlled release to the burners, to maintain safe operation and prevent gas-related accidents.

The grill hose connects the pressure regulator to the burners. This hose transports the gas from the tank, through the regulator, to the burners. Typically, the hose is made from a durable material that can withstand high pressures and outdoor elements, promoting longevity and safety.

What to Do if Your Grill Smells Like Gas

Grease Tray

The grease tray or grease cup, is positioned below the cooking grates of a gas grill. It serves to collect drippings and grease that fall through during cooking. These trays are typically removable, for easy cleaning. This design helps prevent grease buildup in the bottom of the grill.

Pro Tip: Line the grease tray with foil for easier clean-up!

Handles, Wheels, and Cart

The handles, wheels, and the cart of a gas grill are often overlooked parts that are there for the convenience and mobility of your grill.

Without sturdy handles, you wouldn’t be able to easily lift the lid of your grill, while the wheels allow you to move the grill from place to place. A well-constructed cart is also important for providing additional storage for things like propane tanks, utensils, and other accessories.

Other Gas BBQ Grill Parts You May Find on Your Gas Grill

Side Burner | Infrared Rear Burner | Rotisserie | Heat Zone Separators | Rock Grates | Side Tables/Shelves | Illuminated Control Knobs | Hood Lighting | Smoker Box

While all grills should come with the parts listed above, your grill may feature optional parts or accessories that may need to be fixed or replaced from time to time.

The following are the optional features or accessories that you may have on your grill.

A Gas Grill Side Burner

Side Burner

Side burners are typically integrated into a grill’s side shelves, providing an area to prepare sauces or side dishes. This allows you to manage your entire meal conveniently from one spot, keeping everything from appetizers to sauces within arm’s reach while the main course grills.

Here are a few common types:

 

  • Standard Single Burner: The most common type, it’s essentially a single gas burner integrated into the side table of the grill, perfect for heating sauces or side dishes.

  • Power Burners: Larger and more powerful than standard side burners, power burners can accommodate larger pots and reach higher temperatures, suitable for boiling or frying.
  • Griddle Side Burners: Some side burners come with a flat griddle surface, perfect for frying eggs, making pancakes, or cooking bacon outdoors.
An Infrared Rear Burner on a Gas Grill

Infrared Rear Burner

An infrared rear burner, often used with a rotisserie accessory, is located at the back of the grill. This burner is designed for intense, direct heating, allowing for faster searing and reduced pre-heating times.

This setup speeds up cooking and broadens the range of grilled foods, including crispy rotisserie chicken.

A Gas Grill Rotisserie Kit

Rotisserie

A rotisserie, either integrated into your grill or available as an add-on accessory, enhances your grilling options by allowing you to slowly rotate meats and whole poultry.

A traditional rotisserie is typically mounted at the back of the grill’s cooking area above the grates. This location allows the rotisserie to utilize the heat from the main burners or a dedicated rear infrared burner, which provides direct, intense heat suitable for rotisserie cooking.

A motor, which rotates the spit rod, is usually mounted on the side of the grill for easy access and operation without constant manual intervention.

This approach helps your food cook evenly and keeps it juicy and full of flavor.

Types of Rotisseries found on gas grills:

  • Standard Rotisserie: Usually comes with a motor and a spit rod, suitable for most grilling needs, especially for cooking whole chickens or roasts.
  • Adjustable Rotisserie: Features adjustable elements, such as the height or distance from the heat source, allowing more control over cooking temperatures and speeds.
  • Flat Basket Rotisserie: Uses a flat basket instead of a spit rod, ideal for grilling smaller, flatter items like hamburgers or fish that might benefit from being rotated but do not require spearing.
Gas Grill Heat Zone Separators

Heat Zone Separators

Some grills come equipped with built-in heat zone separators, often removable metal plates, that let you split the cooking surface into different temperature zones.

Mastering zone cooking can elevate your outdoor cooking skills, and these separators simplify creating and managing these zones.

They’re great for when you’re cooking a steak and you want to grill some veggies at the same time. The separators help keep the temperature of each section of the grill more manageable.

For more information on zone cooking techniques, you can read our guide:

Zone Grilling Methods for Mastering Your Grill and, How to Control the Temperature on a Gas Grill: Tips for Perfect Grilling

Gas Grill Rock Grates

Rock Grates

Rock grates sit just above the burner and are designed to hold lava rocks (old school) or ceramic briquettes.

These “rocks” do more than just shield the burner from grease and marinade drippings; they also help distribute heat more evenly across the grill.

Gas Grill Side Tables/Shelves

Side Tables/Shelves

Side tables or shelves on a gas grill are typically located on either side of the grill’s main cooking area.

They are attached to the main body of the grill and provide convenient, easily accessible space for placing cooking utensils, ingredients, plates, and other important things, like your beer!

Some models might also include additional features on these side tables, such as built-in burners or tool hooks.

Gas Grill with Illuminated Control Knobs

Illuminated Control Knobs

If you ever grill at night, illuminated control knobs are an incredibly valuable feature for your gas grill to have. These knobs feature backlighting that makes them visible even once the sun has set.

Some models of illuminated control knobs on gas grills can change colors based on the temperature setting. This feature enhances usability and safety, allowing you to gauge the heat level at a glance visually. Typically, the knobs might glow a cooler color like blue at lower temperatures and change to red as the temperature increases.

Hood Lighting on a Gas Grill

Hood Lighting

Hood lighting is a fantastic feature for those who love to grill after the sun goes down. These lights are typically mounted under the hood and may be motion-activated.

When you lift the lid, it automatically turns on, illuminating the entire cooking area and making it easier to see what you’re doing without additional lighting.

Gas Grill with Smoker Box

Smoker Box/Charcoal Tray

A smoker box allows you to add charcoal or wood chips to your grill to infuse your food with delicious smoke even as it cooks on a gas grill.

Some higher-end gas grills come with a built-in smoker box, adding convenience for those who appreciate the depth of flavor that smoking can bring to their grilled foods.

This feature is typically integrated into the grill’s main structure in grills that include a built-in smoker box. The most common placement for a built-in smoker box is next to or between the main burners.

It may be situated in a dedicated area that allows easy access for filling and cleaning, often found under the cooking grates but separate from the primary cooking area.

The built-in box is usually made with the same high-quality materials as the rest of the grill.

Most Replaced Gas Grill Parts

In gas grills, certain parts are more prone to wear and tear and typically need to be replaced more often than others.

Here’s a list of the most commonly replaced gas grill parts:

  • Burners: The most frequently replaced part, as they are constantly exposed to high heat and corrosive food drippings, which can cause them to degrade over time.
  • Venturi Tubes and Clips: these are also prone to wear down over time from exposure to high heat, and grease build-up which causes moisture and corrosion.
  • Igniters: Because they are used every time the grill is turned on, igniters can wear out and require replacement.
  • Cooking Grates and Warming Racks: Repeated exposure to high temperatures and scraping can wear down grates. The outside elements can also cause rust over time.
  • Flavorizer Bars or Heat Tents: These can rust or degrade with use and heat exposure or the outside elements.
  • Grease Trays: Even with regular maintenance, the harsh conditions under a grill will eventually degrade the material of the grease tray.
  • Grill Hoses and Regulators: Over time, hoses and regulators that connect the gas supply to the grill can wear out or become damaged.
  • Thermometer or Heat Gauge: Replacement may be needed if it becomes inaccurate or stops working.

Occasionally, less frequently used parts such as rotisserie rods, hood bumpers, wheels, digital thermometers, lid handles, air valves, ignition switches, and side shelves might also require replacement.
