Depending on your grill, the hookup for your gas may vary. When in doubt, follow the usage instructions. If you don’t have these, look up a digital manual with a keyword search for your grill online. Some grills may be connected by a direct line to the natural gas supplied to your home. This kind of gas supply acts the same as a tank, but is stationary. Smaller tabletop grills oftentimes have small canisters of gas which are screwed into the valve of the grill before it can be ignited.

Different grills may have different designs, like ones that have the starter and regulator knob combined. Follow the grill instructions when confused about the ignition procedure. Once one burner is lit, you can light burners next to the lit one without the igniter by simply turning on the regulator knobs for these burners.

Gas inputs and outputs are usually preceded or followed by a shutoff valve and are frequently shaped like spigots. [5] X Research source

After your first burner lights, it’s a simple matter to turn on the regulator knobs for the other burners. They should light off the flame already burning in your grill. Some models of grill may not have lighting holes or might have poorly designed ones. In this case, stand as far from the grill as you can and use a long stick match to light the grill.

If the rubber of your supply line feels brittle, it’s a good sign the line should be replaced. Replacement parts can be found at most hardware stores and home centers. When the grill and gas supply are properly hooked up and the gas turned on, a hissing sound, especially from connectors or valves, could be a sign of a gas leak. Leaks can result in fire or explosions. Turn off the gas and stop using your grill immediately if you suspect a leak.

Sometimes you can tell when an igniter is bad by the sound it makes. If you push your igniter and it makes a different sound than normal, this could indicate that your igniter no longer works.

Before replacing your burner, try resetting its regulator. This may not be possible for all grills, but if it is for yours, instructions on how to do this will be in the grill’s manual. You can usually replace burners inexpensively with a suitable new part purchased from a hardware store, home center, or the manufacturer.

Igniters, in some cases, use a small battery to power the ignition mechanism. The placement of this part will depend on your grill, but many times it is situated close to or underneath the igniter switch. [11] X Research source

If your tank has frozen, you won’t be able to use it until it has thawed. Bring the tank in a warmed location, like a shed or basement, so it can thaw.
