Turn It Off!- Turning Off The Fuel Source

Turn It Off!- Turning Off The Fuel Source

You might be surprised at how often we get calls from customers who leave their propane tank valve on when they aren’t using their grill.

Along the same lines, many customers who own natural gas grills leave their supply line shut-off valve open when they are not using the grill.

Propane tanks and natural gas lines are both “fuel sources” for gas grills. Many customers who leave their fuel source “on” do so as a matter of convenience. It’s one less thing to turn on or off before and after grilling.

Regardless of the fuel source, for safety reasons, it’s very important to turn off the supply of gas to the grill when it’s not in use.

If someone or something were to turn on one the control knobs on the grill, it would fill with gas, creating the potential for a very dangerous situation. The best case outcome to this scenario is that the customer would have wasted their gas.

Another scenario involves rodents and wildlife. This one might sound funny, or unlikely, until it’s happened to you. It’s not unheard of for wildlife to chew on gas hoses, and should an animal do so on a gas hose that’s connected to a fuel source that has not been “turned off” a gas leak may result, which is of course a dangerous situation.

In addition to safety reasons, for LP (propane) grills, leaving the tank valve on can easily lead to a grill going into reduced gas flow state known as bypass. When in bypass, the grill won’t reach its proper cooking temperature range, often getting no hotter than 250 to 300F. Click here for info on bypass.

Leaving the fuel source to a grill “on” can be convenient, but it’s greatly overshadowed by the potential for danger, and how long does it really take to turn a valve anyway?

Would you drive around with your cars gas tank hatch open to save a few seconds at the gas station? Would you leave your front door wide open while you are gone because it takes too long to turn the door knob when you got back home? Be smart…turn off the fuel supply to your Weber® Gas Grill!

I have a Weber Q which I have only used a few times. Tonight I ended grilling and turned off the gas valve. I forgot to turn off the dial on the BBQ. An hour later I checked on it and it was still heating up even though the gas was off. Why? Does it not turn off when the gas is off? I am very upset.


John Burns

Hi Lynda, I’m sorry to hear of the recent experience you had with your Weber Q. The tank valve on your LP tank must not have been completely closed, as it is impossible for the grill to continue producing a flame from the burner tube(s) without a supply of fuel. This situation also illustrates the importance of always turning off the control knobs on grills before turning off the fuel supply. If you’d like to discuss the matter further please feel free to contact Weber Customer Service at 1-800-446-1071. We’re open 7am to 10pm CST, 7 days a week.

Hi; I'm a newbie here and I'd be interested on your recommendations for shutting down a charcoal grill (kettle) and also what are some techniques available to get the grill to cool down enough to where it's safe to put on the cover without risking damaging it (spraying coals with water and rust).


John Burns

Hi Jaiker, Thank you for the great question and welcome to the Weber family! The best way to get your coals to go out is by fully closing the vents on the bottom of the kettle and closing the damper on the lid to cut off the oxygen supply to the coals. This will cause the coals to be extinguished. How long that takes depends on how much charcoal you still had left. However, this technique will cause the grill to hold its temperature for quite a while, as the heat from the coals is going to take a while to cool down. Once the coals have completely gone out you can then open the vents on the bottom of the kettle, and hang the lid on the side of the kettle by using the lid hook to let the grill cool down rapidly. Once it’s cooled down you can put your cover on. I hope this helps, and don’t hesitate to reach out to us if you have more questions! Thanks! John Burns
