What are gas grill regulators and do you need to replace yours?

The term “regulator” is usually used in the grill world to describe the gas grill regulators, hoses and fittings that bring gas from your LP tank and connects it to your grill.

Standard Single-Hosed Gas Grill Regulators

Technically, the regulator is the silver colored disc part that looks like this:
Gas Grill Regulators

The hose connects it to the brass fitting which is the part that screws onto your grill. Right next to the regulator is a collar that twists freely. That’s the part that screws onto the LP tank. Though you should always turn off your LP tank when you’re done cooking or when you’re changing the regulator, LP tanks are made with an automatic shut off valve. It will only work when a regulator hose is connected to it.

How do you know when it’s time to replace your regulator?

As I mentioned, the regulator brings gas to your grill burners. Here are some indicators you need a new gas grill regulator

  • Low heat coming from your burners when your gas is turned on high. Do a visual check on your burners to make sure they are all in one piece and there are no obvious holes or problems.
  • Your burners light up unevenly. For example, if the burner on the far right flickers or hardly lights, the middle burner has low flame, and the left burner has a normal looking flame.
  • Over time your grill gets less and less hot. Last week it took 10 minutes to grill some burgers, but today it took 15 to grill the same burgers.

WHY? Regulators, for safety reasons, close down slowly over time as they “go bad.” You probably won’t notice one day your grill is perfect and the next it doesn’t light at all. The burner closest to the source of gas will light up better than those farther down the manifold. Your grill will get to lower and lower temperatures over time, even on “high” heat. The main indicator of needing a new regulator is low heat or low flames, especially if it’s getting worse over time.

What else could go wrong?

Keep in mind that you may also have a problem running along the hose. Be aware of the smell of gas even when your grill is off or a tiny hissing sound.

Some animals like to chew on the sun-baked rubber hoses. (Don’t knock it ’til you try it?) If this is a problem for you, they have invented handy-dandy hose guards. Check them out.

If you think there’s a leak, but you’re not sure, you can check the hose with some very soapy water. Rub the suds all the way along the line of the hose. Turn on the gas tank. If there is gas escaping, it will cause the soapy water to bubble at the point of the leak.

What are the differences in gas grill regulators?

A single-hosed, standard regulator is the most commonly used part on grills. It’s the picture I used above. These regulators let out up to 60,000 BTUs of gas.

If you have a side burner, check out this dual-hosed standard regulator. There is one regulator (remember that’s the disc) and there are two separate hoses. Sometimes one hose comes off the regulator and splits into two hoses, forming a Y shape, and sometimes there are two hoses coming directly out of the regulator itself. Either will work and they are interchangeable.

Updated June 2021: Many of our gas grill regulators now support high-flow needs (let out up to 90,000 BTUs of gas). These are compatible with grills that originally used a standard flow. However, please note that your high setting might give you more heat than before. Pay attention the first time you grill with a new regulator and take note of the cook temps!

How do you know?

Usually, the removal and visual inspection of your regulator determines which replacement you need. It’s also a good idea to measure the existing hose and/or the space a hose needs to stretch to reach from the tank to the valve or manifold. If you’re not sure, call 678-272-2451. The staff at is always happy to help.

Special Cases

Keep in mind, a standard regulator and hose will not work if you have:

  • Natural gas grill (NG)
  • A crimped hose onto the valve or manifold in your grill. You will know because you won’t be able to unscrew the hose from your grill. In this case, you need to contact your manufacturer to replace the entire valve system.
  • Male fitting on the end of the hose that connects to the grill.
  • Hose fitting larger or smaller than a 3/8″ flare, which translates to about a 5/8″ inner diameter measurement of the opening at the end of the fitting.

Here’s a picture of the fitting:

Gas Grill Regulators Female Flare Fitting
You can’t measure the 3/8.” It’s confusing, I know. Like I said, check for a 5/8″ measurement.

The good news is that this can be the easiest, cheapest part of your grill to fix!

Remember, not all regulators are created equal. Lower quality rubber will degrade and break more easily in the sun. A lower quality regulator can go bad more quickly.

How many PSI is a grill regulator?

High pressure regulators regulate the output pressure from 1 psi to as high as 60 psi. There are a number of different high pressure regulators available. Some high pressure regulators are "preset". That is, the propane pressure is fixed at a certain pressure; i.e., 10 psi or 20 psi.

Click to see full answer.

Similarly, it is asked, what PSI should a gas grill regulator be?

The propane barbecue can use a high-pressure propane delivery system, which requires a high-pressure regulator. This can vary from between 10 and 60 psi (the pressure measurement). Or, you can have a low-pressure delivery system (for propane barbecues up to 50,000 btu).

Secondly, what is the difference between a high pressure and low pressure propane regulator? Differences Between Low- & High-Pressure Propane Burners. Low-pressure propane burners regulate gas intake to about 6 ounces per square inch, whereas high-pressure burners regulate gas intake to between 1 and 60 pounds per square inch. The intake difference determines the burners' application: outdoor or indoor.

In this regard, what is the PSI of a low pressure propane regulator?

The typical high pressure regulator is set around 10 PSI. Low Pressure LP is rated in inches of water column (in WC). The typical rating for low pressure LP is around 10.5 - 11 inches WC.

Are all gas grill regulators the same?

Every propane gas grill uses an LP regulator, but not all regulators are created equal. There are many types of gas regulators available including : High-Pressure Regulators, First Stage Regulators, Second Stage Regulators, Integral Twin Stage Regulators and Appliance Regulators .

Do you want to know how to reset the gas grill regulator? It can be because you turned the grill on to warm it up, hoping that the grill will be ready to cook by the time everyone arrives. Then you realized that the flame is weak, and the grill temperature only goes up to 250 or 300 degrees Fahrenheit. Started to panic? Read this to know the proper way to rest the gas grill regulator before calling your BBQ Grill Repair Company.

Before we dive headfirst into the solution, let’s take a look at …


What you’ll learn about How to Reset a Gas Grill Regulator

Why here? You’re right to think about why we have added a summary at the beginning of the article. The reason is, a glance will help you know that you’re at the right place to learn about regretting the propane regulators.

A gas grill regulator is a small device that is screwed onto an LPG or propane tank. It regulates the gas flow from the gas tank. It also includes a safety mechanism known as a bypass. The gas regulator consists of a ball and spring and automatically cuts off the gas supply when the hose is devoid of back pressure. Generally, it happens when there’s a leak. It can also be activated if the gas tank and one of the burners are turned on. You should turn off the gas tank and wait for a while before turning on the burners.

The grill regulators (or pro

pane gas regulators) are a component of the gas grills that controls the gas flow from the fuel canister to the heating element. It also acts as a safety barrier between the high-pressure propane tank and the heating appliance.

In short, it brings the pressure of the propane down to a safe level. If the pressure is too low, the grill may not heat up. If it is too high, it may cause a flameout (or worse).

How does a Gas Grill Regulator Work?

The regulator is bound to a propane tank to manage the gas flow to the burner of your grill. The higher the gas flow, the larger the flame, and thus the more heat. If the gas flow is low, the flame will be small, and the amount of heat will be low.

In addition, the regulator has what is called a bypass, which is a plastic mechanism that cuts off the gas supply when there is no pressure in the hose extending from the grill. This can be caused by a gas leak or by leaving the burners on for a long time.

What is Bypass Mode?

All BBQ gas grills have a regulator, which, as the name implies, regulates the flow of propane gas. The regulator has a built-in safety mechanism called a bypass valve. This bypass valve system sits between the regulator and the propane tank. Take a look at the image of the bypass system. 

In the image shown below, the system is in a locked state. This is the activated or tripped state of the safety mechanism. In some cases, this is caused by gas leakage, but in most cases, it is due to the user using an improper ignition method.

As shown in the image, the safety device of gas regulators consists of a ball and a spring. The pressure from the propane tank pushes the ball against the spring. When it happens, a gas flow is established. If there’s a leakage or burners are left open, the reverse flow of the air pressure doesn’t let the ball displace from its position inside the regulator. As a result, propane from the LPG canister can’t pass through the safety device.

If you don’t light the grill in a certain way, the safety device will mistake it for a leak and reduce gas flow from the canister to less than 10% of normal. This condition is called “bypass.” When the gas supply is reduced, the grill cannot be brought up to its normal temperature, and in some cases, the grill will not light.

If you find yourself in a bypass situation, please check for leaks first (that’s what the safety device is for).

What’s the Proper Ignition Sequence for Gas Grill?

Following the proper ignition sequence for your gas grill is important to prevent your grill from entering bypass mode.

If you do not find any gas leaks, you can follow the steps below to get out of the bypass and not enter the bypass in the future.

The way to prevent yourself from entering the bypass is very simple.

  • Open the lid of the grill.

Ensure the grill lid is open and all control knobs are turned off (side burner knobs included, if any).

Open the tank valve at the top of the propane tank to connect the gas supply.

Wait a few seconds for the hose to build up pressure before doing anything else. This pressure will push the equipment in and give you the “all clear” to operate normally. It should be noted that allowing the pressure to build-up is the most significant part of the entire process.

  • Turn on the Burner and Push the Ignition Button

After a short wait, turn the appropriate burner to start/high and press the igniter button to ignite, just as you would with a normal grill. The actual ignition method will vary depending on your particular model. Please refer to your owner’s manual for details.

Light all main burners, turn the temperature to high, and close the lid. After about 10-15 minutes, if the temperature reaches 500-550℃, the liquid propane grill is working properly.

Basically, the key is to always turn off the burner before you turn on the liquid propane tank valve. If you turn on the burner first, the gas won’t be pressurized in the gas line, and the bypass will be activated. 

To the system, it looks like there is a leak, so the bypass is activated or triggered. (Even if there is no gas leak, the system will think there is a leak because of the low back pressure.)

Side note: If used in the wrong order, the regulator will trip. Turning the burner on first will empty the propane line, resulting in low line pressure.

How do I Know if My Grill has a Faulty Propane Tank Regulator?

Possible indications of a faulty regulator or appliance include:

  • A lingering yellow or orange flame
  • A popping sound when the grill burners are turned off or on 
  • Floats of flame above the burner port
  • Roaring sound from the burner, 
  • Flames appearing at the burner intake
  • Flame overflow from the burner or a large amount of soot.

In most cases, performing a propane regulator reset will get the job done for you. However, sometimes, especially if there’s a severe issue with the propane regulator, resetting the regulator isn’t the option, and you’ll have to replace it.

When Should I Perform a Regulator Reset?

You need to reset the regulator if:

1. The burner does not light up 

Despite making all efforts, the gas grill fails to ignite: whether through electric ignition or manual, the problem can be with the regulator.

2. Grill is not hot enough.

It’s not necessary the failure to ignition can indicate that you need to reset the regulator. In fact, low temperature can also be the reason for propane regulators in need of a reset.

3. The disturbed flames’ pattern

If you see that the flame of your gas grill is of bright yellow or orange color or not even, it can hint at the regulator reset.

Also, please note that the flame should always be blue. If it’s not and you’re constantly getting the yellow flame, it’s problematic, and you can go ahead either clean your burner tubes or reset the gas regulator.

How do You Test the Gas Regulators?

If the gas regulators continuously trip, there may be a leak in the hose. Close the valve on the gas tank and disconnect the regulator and gas line from the propane tank. Immerse the regulator in a solution of soap and water, then attach the regulator and hose back to the gas container. 

Make sure the burners on the grill are “off,” and the valve on the tank is turned on. Soap bubbles will indicate the location of any leakage in the regulator or hoses. Replace the regulator or hose as necessary.

How to Reset Your Propane Regulators?

Now that we know what the problem is with the propane regulator, let’s try to come up with a solution. Of course, this assumes that you have checked your gas container to see if it simply needs to be replaced with a new propane tank.

This is the complete step-by-step process for how to reset the gas grill regulator.

  1. Cut off the supply from the fuel container.
  2. Turn the shutoff valve on the propane tank to the OFF position by rotating the valve clockwise until it is fully closed. 
  3. Disconnect the hose from the gas tank.
  4. Lift the barbecue grill lid to make sure there is no gas buildup.
  5. Make sure all burners are on “high.”
  6. Wait for 2 minutes and don’t do anything.
  7. Switch off all burner valves.
  8. Now reconnect the hose to the fuel container.
  9. Slowly turn on the supply from the fuel container by rotating the valve counterclockwise. Make sure you do it very slowly to avoid tripping the regulator. 
  10. Ignite the grill to resume its normal operation.

Final Thoughts

When it’s about cooking on your grill, a tip-top gas regulator can guarantee the constant flow of heat for your BBQ and save you from distress. The regulator reset call, however, needs the right identification of the problem first. It might be your grill regulator demands to be replaced, and working on the valves can be of no help. You can take the right steps by following this quick guide. Hence, if your grills fail to serve your outdoor cooking with sufficient temperature, follow this expert guide on how to reset the gas grill regulator.

How Regulators Work

Bypass Mode

Suni Gas grills all have a Propane regulator that does as the name implies – regulate Propane. It’s an essential grill part. Regulators have a safety mechanism inside of them called a bypass. Have a look at the bypass image we have here. This bypass is in the locked position and shows what it looks like if the system has been triggered. This can be caused by a leak, randomly or, and this is usually the case, a user using the improper ignition sequence.


The Proper Ignition Sequence

So then what is the proper ignition sequence? First, let’s identify the improper sequence.

* Side note about the shut down procedure. The following ignition sequences are written assuming you are turning the burners off 1st, then the Propane Tank. Therefore, each sequence starts from the “all off” positions. You can turn the burners off and leave the Propane Tank on; however, we strongly recommend you to go ahead and turn the Tank off also.

Improper Ignition Sequence.

*** Everything starting from off/closed position.
1. Turn on burners.
2. Turn on Propane.
3. Ignite.

The Proper Ignition Sequence

*** Everything must be off to start – the propane tank and burners.
1. Turn on your propane tank.
2. Now, you can turn the burners on.
3. Ignite.

To put it simply, the key is to be sure you have your burners off before you turn on the Propane. If you turn the burners on first the gas will not be pressurized in the gas line causing the Bypass to trigger. You see, in this case the system detects there is a gas leak; hence, the bypass triggers.

(Even though there is no leak; because the back pressure is low the system will think there is.)

* When using the improper sequence, the regulator will trip because by turning the burners on 1st, you empty the lines of any propane which causes the low line pressure.


When should the Regulator Reset be performed?

1. The burner will not light with igniter or match.
2. Burner does not get hot enough.
3. Low or incomplete burner flame pattern. “Also, the flame should be blue. If it’s mostly yellow that’s an issue.”


How To Reset a Regulator

So now having a thorough understanding of the problem, let’s get you the solution.

1. Turn off the gas at the propane tank.
2. Disconnect the hose from the propane tank.
3. Open the lid of your BBQ Grill.
4. Turn all the burner valves to high.
5. Wait for 2 minutes.
6. Turn off all the burner valves.
7. Connect the gas line back up to the propane tank.
8. Turn on the propane tank slowly.
9. Light the grill using the proper ignition sequence.

In Conclusion.

If after having deployed this fix the issue persists, it’s time to call your local BBQ Grill Repair Company. There are numerous other more advanced issues that can occur. For instance, you may have a blockage in the Venturis Tubes. A blockage like this is caused by char/grease build-up. You can decrease the likely hood of this ever happening by being sure to have a BBQ Grill Cleaning done regularly.

What are OPD Cylinder Valves?

OPD Cylinder Valves
In response to this post, one of our Facebook users asked:

Is there a similar device in the tank valve or just in the regulator?

The answer is yes, there is a similar device called an OPD Cylinder Valve, but there are also numerous important differences.

An OPD Cylinder Valve is indeed a part of your propane tanks’ inherent safety design. However, it does not have a “Bypass” as your regulator does, nor is it designed as a safety mechanism during usage. This device is required on all 4 to 40 pound DOT cylinders.

OPD stands for Overfilling Prevention Device and its first function is to do just that, prevent the user from overfilling the device. In addition, the device disallows Propane from flowing out of the cylinder if the triangular handwheel is opened and there is no gas line connected. It does this because there is no connected regulator to push open the valve’s orifice. Moreover, Propane OPD valves operate inside the bottle and are activated as the cylinders liquid propane rises in level pushing the float upward, therefore, stopping the flow of gas into the tank. This action is similar to that of a toilets float valve; once the water in the bowl rises to a certain level, the flow of water stops.

The OPD Valve is one of the main focuses regarding the fact that tanks are to be recertified 12 years after original manufacturer dates and every 5 years thereafter. Inside, there are what you can call “O-Rings” that need to be changed out at those predefined intervals. Also, the mechanism itself can be swapped out for a new one. Tampering with this device is NOT RECOMMENDED. If you suspect there’s an issue call your local propane delivery supplier and they will deal with it properly.

Regulator grill pressure

Juan Ramirez

20:59 26 Oct 19

We had a family event (BBQ) but last time I tried our grill It did not work. Unfortunately I did not have time to fix... it and I was traveling this week,, so I decided to look for a pro in order to make sure it was working properly for our celebration. I called this company and they came to my property two days later (Friday October 11th) tested the grill, changed a valve /Igniter for what I got a $289.00 bill which I accepted and paid. The same day they recommended through a third person who sent a text message a $200 plus deep clean and a maintenance plan (both absurd in my opinion) Two days later, on Sunday Oct 13 while we were in our family event, I found out that one burner was not working and a second one was very weak. On Monday I called Grill Tank Plus and requested them to come again since the grill was not working properly as they had confirmed. Last Thursday Oct 24th a new technician came to inspect it and I received a call to let me know that two additional valve/Igniters were not working and needed to be replaced. He also told me that for the new visit I had to pay additional $120 which I disputed with his supervisor and he agreed to wave it , conditioned that in the new fix I would have to pay it. Two hours later I got a quote of $300.oo for the new fix which really impacted me. How come in the first inspection they did not find anything else and confirmed it was working properly. If you add the two bills it would be near $600, if you continue with the $200 deep clean it would be $800.oo what's going on here?? Does it make any sense? What type of company is this???? Please read attached pictures of the first bill, the quote and the text message more
