What Size Pipe Do You Need for My Natural Gas Grill?

If the thought of installing a natural gas grill has you feeling a bit overwhelmed, you’re not alone! 

Determining the appropriate size of the pipe for the gas supply can be a complex task that requires a bit of expertise. 

The size of the pipe is dependent on the BTUs (British Thermal Unit) rating of your grill (or the combined BTUs your grill will put out if all burners are turned to high) and the length of the pipe run from the gas meter to the grill. Here, take the following chart and formula to figure out your needs for your situation. NOTE: The chart provided is only intended for reference purposes. To obtain official values, it is recommended to consult the National Fuel Gas Code and the manufacturer’s documentation of your natural gas grill.

  • Natural Gas flow is given in thousands of BTU/hr.
  • One cubic foot of Natural Gas = roughly 1000 BTU
  • Typical nominal pressure at the burner for Natural Gas is 3.5″ of water column
  • Typical machine supply pressure is 5″ to 7″ of water column
  • Pipe length must include additional length for all fittings
  • Add approximately 5 feet of pipe per fitting

An example using the table  

Using the chart above, a machine with a burner that requires 220,000 BTU would need a 1″ pipe for a 20′ run.

How we did it

We got there by taking the 220,000 BTUs and dividing it by 1,000 leaving us 220. then, knowing we need a 20ft run, started in the 20ft row on the left and moved to the right until we got to the first number that was larger than 220 that we need which is 280. Then looked at the top of that column to find the 1” pipe. 

But that’s not all – there are several other factors to consider as well!

Most homes will require a 1/2-inch pipe for natural gas grills. While this is adequate for most appliances, including furnaces, water heaters, and stoves, if you plan to use multiple appliances or expect to use a lot of gas, you may need a larger pipe. 

For example, a home with a furnace and a stove may require a 3/4-inch pipe. But that’s not all – you also need to factor in the length of the pipe run, including additional length for all fittings. 

We recommend when making you calculations adding approximately 5 feet of pipe per fitting you plan to use.

It’s essential to plan the pipe run carefully to ensure the pipe is the correct size and length.

But wait, there’s more! When installing a natural gas grill, you also need to consider the pressure of the gas supply. The typical nominal pressure at the burner for natural gas is 3.5″ of water column. 

However, the machine supply pressure is typically 5″ to 7″ of water column. Therefore, it’s essential to ensure that the gas supply pressure is appropriate for the grill to operate safely and efficiently.

When it comes to connecting your natural gas grill to the gas supply, you need to use a flex hose. Natural gas grills come with some flex hose to connect your grill to the supply line. 

You also need to make sure that the gas valve and the regulator are both in the full “open” position when using the grill. And when you’re not using the grill, it’s recommended that you close the gas valve to stop gas flow.

Factors to Consider When Determining the Size of Pipe You Need for Your Natural Gas Grill

There are several factors that you should consider when determining the size of pipe you need for your natural gas grill. These include:

  • The distance between your natural gas source and your grill
  • The BTU rating of your grill
  • The number of fittings and elbows in your gas line

The Advantages of a Natural Gas Grill?

If you’re in the market for a new grill, you might be wondering why people choose a natural gas grill or a propane grill. While both types of grills have their pros and cons, there are several reasons why you might want to consider a natural gas grill.

Affordability

While natural gas grills may be more expensive to purchase than propane grills, they are typically less expensive to operate in the long run. 

This is because natural gas is generally less expensive than propane, which means that you’ll save money on fuel costs over time. And let’s be honest, who doesn’t love saving money?

But that’s not all – the affordability of natural gas grills goes beyond just fuel costs. Because natural gas grills are connected to your home’s natural gas line, you don’t have to purchase and transport propane tanks, which can save you money in the long run. 

Propane tanks can be expensive, and the cost of transporting them can add up over time. With a natural gas grill, you don’t have to worry about any of that. You can simply fire up the grill and start cooking without any additional costs or hassle.

Increased Home Value

And let’s not forget about the added value that natural gas grills can bring to your home. A natural gas grill is a permanent fixture in your backyard, which can increase the value of your home. 

And because natural gas grills are connected to your home’s natural gas line, they are considered a safer and more reliable option than propane grills, which can also add value to your home.

Environmental Impacts

Natural gas grills are a better option for the environment than propane grills, and here’s why. 

Natural gas is a cleaner-burning fuel than propane, which means that natural gas grills produce fewer emissions than propane grills. This is great news for the environment, as it means that natural gas grills are a more sustainable option for outdoor cooking.

Convenience

Let’s talk about the ultimate convenience of natural gas grills! 

One of the most significant benefits is that they are connected directly to your home’s natural gas line, unlike propane grills that require you to change out the propane tanks when they run out. 

This means that you can grill to your heart’s content without ever having to worry about running out of fuel in the middle of a barbecue. And let’s be honest, there’s nothing worse than running out of fuel when you’re in the middle of cooking up a storm!

But that’s not all – the convenience of natural gas grills goes beyond never running out of fuel. You also don’t have to worry about the hassle of transporting and storing propane tanks. 

Propane tanks can be heavy, bulky, and difficult to transport, not to mention the fact that you have to find a place to store them when they’re not in use. 

With a natural gas grill, you don’t have to worry about any of that. You can simply fire up the grill and start cooking without any fuss or hassle.

But that’s not all – the environmental benefits of natural gas grills go beyond just emissions. 

Because natural gas grills are connected to your home’s natural gas line, you don’t have to worry about disposing of empty propane tanks. Empty propane tanks can be difficult and expensive to recycle, which means that they often end up in landfills. 

With a natural gas grill, you don’t have to worry about any of that. You can simply enjoy your barbecue without any additional environmental impact.

Things to Know About a Natural Gas Grill

So, you’ve decided to switch to a natural gas grill. Before you start grilling, there are a few things you need to know to ensure your grill is safe and working properly. Here are some key factors to consider:
