Gas grill installation: what to know

What the job involves, what changes the price, and what to ask a pro.

What gas grill installation is

Gas grill installation connects a built-in or freestanding grill to a natural gas line or a propane tank. The work includes running or checking the gas line, fitting the shutoff valve and regulator, setting the grill in its cabinet or cart, and testing every joint for leaks. People book it when they buy a built-in grill, move a grill to a new patio, or convert from propane to natural gas.

Signs you need it

  • You bought a built-in grill that needs a gas line run to the outdoor kitchen or patio
  • The grill needs a shutoff valve, a regulator or a flexible connector that is not in place
  • The grill is moving from propane to natural gas, or the other way round
  • The patio or deck has no gas stub-out, and one must be added
  • The grill has a burner or igniter that does not light after the move
  • You are not sure whether the gas line size and pressure will feed all the burners

What the pro does

  • Confirm the grill's gas type, the required supply pressure and the connection size in the install guide
  • Run or check the gas line, the shutoff valve and the flexible connector to the grill, with the gas line work done by a licensed gas trade
  • Set the grill in its cabinet or cart, level it and secure it to the surface as needed
  • Connect the regulator and the propane tank connection, or the natural gas fitting, using the correct thread and sealant
  • Test every joint for leaks with a leak detection solution and confirm no bubbles appear
  • Light each burner, check the flame pattern and the igniter, and show the customer the shutoff and the regulator

What changes the price

Every job is different, so we do not publish prices. These are the things that move the quote up or down.

  • Natural gas versus propane, since the connection and the regulator differ
  • Distance from the existing gas line to the grill, and the trench or conduit needed
  • Whether a new gas stub-out or shutoff valve must be installed
  • Built-in cabinet or freestanding cart, which changes the work and the access
  • Number of burners and the total gas load the line must carry
  • Whether a permit or inspection applies to the gas run

What a written quote should spell out

  • Grill make, model, gas type and required supply pressure
  • Gas line length, material and route, and the shutoff valve location
  • Which licensed gas trade does the gas line work, and the permit status
  • Regulator, flexible connector and fittings, and who supplies them
  • Warranty on the installation and a written record of the leak test

Questions to ask before you hire

  • Will the gas line be run by a licensed gas trade, and can I see the license?
  • Is a permit needed for the gas run, and who pulls it?
  • What does the leak test cover, and will you show me the result?
  • Is the gas line sized correctly for all the burners on this grill?
  • Do you check the regulator and the flexible connector against the install guide?
  • Will you light each burner and check the flame before you leave?
  • Does your warranty cover a leak at a joint you made?

Red flags

  • A gas line run by someone with no gas license in an area that requires one
  • Gas joints sealed with tape or pipe dope not rated for gas
  • No leak test at the joints before the grill is used
  • A regulator or connector that does not match the grill's gas type
  • No permit where the gas run needs one

What you can do yourself

You can clear the work area, read the install guide and move the grill into position with a helper. Do not run, cut, connect or test any gas line, valve or regulator yourself, and if you smell gas, leave the area and call your gas utility from outside. Call a licensed gas trade for every gas connection and leak test.

Licenses and permits

Gas grill installation often requires a licensed gas trade for the gas line work, depending on where you live, and a permit is often required for a new gas run. Check with your state or local licensing agency and your local building department before the work begins.

Gas grill installation questions

Can I connect a propane tank to my grill myself?

Many owners connect a propane tank by following the grill's manual, which includes a leak check of the connection. If you are unsure about the fittings or the regulator, or the grill is built in or runs on natural gas, have a pro do it and test it for leaks.

Why is my built-in grill not reaching full heat?

Low heat can come from low gas supply pressure, a partly blocked burner, a regulator issue or a gas line sized too small for the grill. A pro checks the pressure and the line.
