Understanding Gas Firepit Mechanics

Before diving into troubleshooting techniques, it’s important to understand how a gas firepit works. A gas firepit typically consists of a base filled with lava rocks or fire glass, a gas burner, and a control valve. The control valve allows you to regulate the flow of gas to the burner, and the ignition system – either a pilot light or electronic igniter – lights the gas when you turn on the valve.

Gas firepits require regular maintenance and cleaning to ensure optimum performance. Neglecting regular maintenance can cause a variety of problems, such as a firepit that won’t stay lit or one that has a weak flame.

The most common reason for a gas firepit that keeps going out is lack of maintenance. The burner and control valve can become clogged with dirt and debris, preventing the gas from flowing properly. A dirty burner can cause an uneven flame or even fail to light.

If your gas firepit won’t stay lit, it may be due to a faulty thermocouple. The thermocouple is a safety feature designed to shut off the gas supply if the pilot light goes out. If it is malfunctioning, it may be shutting off the gas supply prematurely.

It’s important to remember that gas firepits are complicated systems and require a certain level of expertise to properly maintain and repair. Regular gas firepit maintenance is critical to keep your firepit functioning properly and safely.

Gas Supply Issues

If your gas firepit keeps shutting off, the issue might be related to gas supply. Several factors can contribute to this problem, including low gas pressure, faulty regulators, or blockages in the gas line.

Low gas pressure is a common culprit for firepit flame instability. If the pressure is too low, the flame might not ignite or stay lit for long. You can check the pressure at the gas regulator using a manometer. If the pressure is lower than the recommended level, you might need to adjust the regulator or contact a professional to do it for you.

Faulty regulators can also cause gas supply issues. If the regulator fails to maintain a steady gas flow, the flame might flicker or go out entirely. Check if the gas regulator is damaged, corroded, or not connected correctly. You can replace a faulty regulator yourself, or seek professional help if you are not confident in your skills.

Blockages in the gas line can obstruct the gas flow and cause the flame to go out. Debris, dirt, or insects can clog the gas line and reduce its efficiency. Inspect the gas line regularly and clean it if you notice any blockages. Make sure to turn off the gas supply before cleaning the line and use a soft brush or compressed air to remove the debris.

Pilot Light Problems

If your gas firepit won’t stay on, the problem could be with the pilot light. The pilot light is a small flame that ignites the main burner, and if it’s not working correctly, the firepit won’t stay lit. Here are some pilot light problems that you may encounter, and how to fix them.

Dirty or Blocked Pilot Orifice

The orifice is a small opening that supplies gas to the pilot light. If it becomes dirty or blocked, the pilot light won’t receive enough gas and will go out. To fix this issue, you will need to clean the orifice using a needle or a wire. Make sure that the gas supply is turned off before doing this.

Thermocouple Failure

The thermocouple is a safety device that detects if the pilot light is lit. If it’s not working correctly, the firepit won’t stay on. To check if the thermocouple is the problem, look for a small metal rod near the pilot light. If it’s not producing a blue flame, it may be faulty and need replacing.

Improper Flame Adjustment

If the flame of the pilot light is too low, it may not be strong enough to keep the firepit burning. You can adjust the flame using the pilot light adjustment screw. Check your firepit’s manual for the location of this screw as it may vary depending on the model.

By addressing these pilot light problems, you should be able to fix the issue of your gas firepit not staying on. Remember to always turn off the gas supply before attempting any repairs and seek professional assistance if you’re unsure or uncomfortable with performing the repair yourself.

Wind and Weather Factors

It’s not uncommon for a gas firepit to go out after a few minutes of use due to strong wind gusts or rain. These external factors affect the stability of the flame and can cause it to be extinguished.
