3 Reasons Why Gas Fireplace Goes Out After A Few Minutes

It can be irritating if your gas fireplace goes out after a few minutes. You may have set up your fireplace only a few days ago. But now your gas fireplace shuts off after 15 minutes. This can happen every hour as well.

When you notice your gas fireplace shuts off after a few minutes or hours, think there can be several reasons behind it. The major reasons are insufficient gas flow, faulty parts in the fireplace, clogged burner ports & insufficient pressure of Oxygen.

Now, let’s know in detail about the 3 major reasons for going out gas fireplace after a few minutes:

1. Insufficient Gas Flow:

If you are burning a large flame for a long time, then you may notice that the gas fire goes out after 15 minutes. The longer you keep the gas burning, the quicker the gas will run out. As a result, the fire burns out quickly.

Basically, the insufficiency of gas flow causes the gas fire to go out after a few minutes.

2. Faulty Parts:

When the parts of the gas fireplace aren’t in the right condition or they aren’t properly placed, then you will notice that your gas fireplace shuts off intermittently.

Mainly a faulty gas valve will result in the type of situation we are talking about. Clogged and dirty burner ports can also prevent fire from lighting up. The burner port is a vital part of the gas fireplace. If it has any fault such as clogging, your fireplace won’t function properly.

3. Insufficient Air Pressure:

It’s a known fact that Oxygen is essential for flames to burn. The absence of it will surely cause the gas fire to go out. If the air intake to the unit is somehow blocked then the gas is not getting enough air pressure to use.

When there is insufficient air pressure and all the oxygen is burned up, the gas fire automatically goes out. There are many factors that can cause the fire of your fireplace to go out. Such as the gas fireplace goes out when it’s windy.   

Now you know which factor is the culprit to shut off your fireplace after it’s on. Now deal with that issue and fix it.

But remember, apart from these 3 factors, there can be a few more issues for which your gas fireplace is malfunctioning. If you want to know about those malfunctions of your gas fireplace and fix them with little repair, then keep reading.

Gas Fireplace Doesn’t Work Properly5 Issues To Fix

You are irritated because your gas fireplace is struggling with so many issues. Don’t worry. Let’s know from which factor your fireplace is suffering and fix it instantly:

1. Gas Fireplace Stays Lit but Pilot Won’t Stay On:

The pilot light is the indicator that helps you to understand the condition of your fireplace. It’s basically a small steady flame fueled by a small stream of gas.

It shows that the fireplace still has gas running. This is why a functioning pilot light is very important. If the pilot light isn’t on even when the fire of the fireplace is still running, you will have to take some simple measures.

First, shut off the gas feed and wait for a few minutes. This will make sure that there is no excess gas built up in the system. After a few minutes, the pilot is supposed to light up. If the flame isn’t on yet, repeat this process. 

2. What To Do If Gas Fireplace Goes Out and Comes Back On:

Sometimes you will notice that the gas fireplace won’t stay lit but the pilot light stays on. The fire will blow out only to come back on again. What can you do if this happens?

You can deal with two things in case this happens. Firstly, test the gas valve at the PV and PV/MV connections. If it seems okay, then the problem is probably with the main burner. When the burner of a fireplace gets too dirty and has debris clogged in, it won’t stay ignited.

The debris will only allow an inconsistent flow of gas. This can make your fire blow out and light back again.

So, when this happens, closely examine the burner and if you find that it really has dirt, clean it properly. You can use a can of compressed air to blow out the clogged debris from the area.

3. What To Do If Gas Fireplace Won’t light:

If your fireplace won’t light at all, you have to detect the problem first. The fuel is a great factor here. If the fuel is not properly burning, then your fireplace won’t burn. In this case, refill the fuel tank and check if the gas tank is perfectly fine. Try to look for cracks.

Another major issue that can cause your fireplace not to light is a faulty ignition fuse. In most gas fireplaces, there is electronic ignition. Its purpose is to ignite the flame that will be the fire of your fireplace. Several issues can damage the electronic ignitor. You may even need to change the fuse.

4. What To Do If Gas Fireplace Smells Like Gas:

If you are smelling gas from your fireplace then you should immediately turn the fireplace off. Smelling gas means there is a leakage. Even a small crack can result in irrevocable disaster. 

After shutting off the fireplace, open up the windows of your room to allow the gas to escape. Taking further measures by yourself can be risky. Rather, it’s better to call a professional in this situation. 

5. What To Do If Gas Fireplace Won’t Turn Off:

Your gas fireplace may not turn off because of some defects. Even if you turn off the wall switch and close the gas valve, the gas fireplace can still stay on. In this situation, there are 2 things you can do:

Rewiring:

Cut off the fireplace from the three-way switch. This way your fireplace won’t have any supply of power to stay on and should turn off immediately.

Installing A Thermostat:

You can use a thermostat as a switch. Install a millivolt thermostat if the fireplace doesn’t go off. The thermostat works for two reasons. 

Firstly, it doesn’t function with traditional 120V which can be problematic sometimes. And secondly, the thermostat shuts your fireplace off automatically after it has reached a certain level of temperature. 

It can be annoying if your fireplace goes out after 15 minutes of burning. But you won’t have to spend dollars to solve this issue. If you can follow the solutions we discussed above you will be able to deal with your gas fireplace effectively.

Just maintain patience and you are good to go.

3 Ways To Check Whether Your Gas Fireplace is Safe or Not

It can happen sometimes that you think there is something wrong with your gas fireplace but you are not sure. Debris, water, excessive heat, and many other issues can cause problems with your fireplace.

Keeping your faulty fireplace the way it is can result in disaster in the future. So, when you feel that there is an issue with your fireplace, it’s always wise to be sure. It’s even better to check your fireplace every time while lighting it. This way your fireplace will last for a long time.

Here are 3 ways to check if your gas fireplace is safe to use:

1. Check If Everything is in Proper Condition:

Clogging is a big issue when it comes to a gas fireplace. Debris usually clogs the path for gas and fire. This results in clogging. It prevents fire from burning properly. Check the connection between the fuel tank and the burner. If there is any form of leakage or defect it can be problematic.

2. Look At The Flame:

A good gas fireplace will have a perfect flame. Take a closer look at the flame quality. It must be clean, bluish and will ignite instantly. The flame will be upward and will be free from odor or smoke.

If it doesn’t light up the moment you start the gas or the flame is unstable in any way then there are definitely some problems. Check the burner and the gas vault for obstructions or debris. 

3. Examine The Chimney:

The chimney is one of the main components of a gas fireplace. To make sure your chimney is ready to be used, you have to observe it from outside. Use a ladder to get closer to the chimney or use a binocular to determine if the chimney cap is properly attached to the top of the chimney. 

The purpose of these caps is to prevent animals, trees, and rain or snow from entering the chimney. It is an essential safety measure. If your chimney is blocked then you should fix it before lighting up your fireplace. You can call a professional for this task.

After you have properly checked these points, you can rest assured that you won’t have any problem operating your gas fireplace.
