How Long Do Gas Logs Last? When & How to Replace Gas Logs

So you have a gas log fireplace, and you absolutely love it. From the efficiency to the aesthetic, you feel as if your gas fireplace offers all the benefits of a real, wood-burning fireplace, without all the hassle. Life is good!

However, like any home appliance, gas fireplaces require routine maintenance. And while you certainly won’t be replacing your gas logs as often as you would with real firewood, there comes a point in time where they’ll need to be swapped out with replacement gas logs. But how long do gas logs last? In this blog post, we’ll talk about when to replace gas logs and how to replace them when the time comes.

How Long Do Gas Logs Last?

So, when exactly should you replace your gas logs? The answer depends on some different factors, including:

  • Material: Gas logs are usually made of ceramic, which allows them to withstand very hot temperatures. Log sets that use cement logs will fade in appearance over time. Depending on use, they can begin to lose their appearance in 2-3 years.
  • Type of gas logs: A well maintained vented log set with ceramic logs will last a very long time, in some cases 10 or more years. A well maintained ventless log set with ceramic logs can also last a long time, but, if heavily used, will begin to wear in 3-5 years.

The short, concise answer is — the higher the quality and the less you use your fireplace, the longer your gas logs will last. However, even with regular use, a high-quality gas log set should last you for a few years or more.

So, how do you tell if your gas logs are high quality? Made in the USA is a good indicator of a quality set of gas logs. Additionally, you’ll want to pay attention to the material. Ceramic is durable and able to stand up to the hot temperatures of a fireplace.

How to Replace Gas Logs

The replacement process for gas logs varies depending on the model you’ll be installing. However, in general, the process looks somewhat like this:

  1. Turn off the gas.
  2. Remove the old logs from the fireplace. You may want to wear protective gloves to keep your hands clean and protected.
  3. Remove the grate. Your grate is likely secured in place with screws, so be sure to have a screwdriver on hand to remove those and then the grate.
  4. Disconnect the burner and gas line.
  5. Clean out your fireplace. This will ensure a safe installation process of your new gas logs.
  6. Connect the new log set’s gas line to the burner.
  7. Secure the burner and grate. Again, you may need to use a screwdriver or other tools to do this — check your log set model for specific instructions.
  8. Inspect the log set for leaks. This is very important! Don’t skip this step. To test for leaks, turn on your gas supply. Then, use a spray bottle to spray a small amount of water and soap on the gas line connection. If bubbles form, you’ll know there’s a leak. Tighten the connection or replace the gas line altogether.
  9. Install the gas logs. Again, be sure to look at your instructions for specifics on how to place your gas logs on your burner and grate.
