Why Is Soot Build-Up In My Gas Fireplace

If you have a gas fireplace or are considering one, you may have been sold on less upkeep, mess, and smell. While this is true and they produce much less soot and smoke, there are times when you may notice soot in larger quantities than you’d think. Let’s take a closer look at why this may happen and some steps you can take to mitigate this occurrence.

Is it Soot?

Luckily, if you’re questioning if there is soot build-up, it is probably on the minor end of build-up. However, that doesn’t mean there isn’t any soot building up on your fireplace. One way you can check for soot build-up is to take a white cloth or paper towel and wipe the logs and fireplace doors. Make sure the fireplace and components are cool and you don’t try to do this test too close to your last fire. If there are any black marks on the cloth or towel, then you know you have a soot issue.

Why is soot build-up a thing?

While it’s less common in gas fireplaces than wood-burning fireplaces, soot can occur if a fire log is blocking the flame path. Any obstruction can cause soot formation as it makes for a less clean burning path. You can also check your gas burner port because they can get clogged as well. If you notice these causes, it’s probably best to call a professional. While the fix may seem simple, it can be dangerous if you’re unfamiliar with the components of the fireplace.

Other Potential Causes

• Do you have an older gas fireplace? As burners age, gas is emitted differently. This may cause flame patterns to look different, additional soot to accumulate, or fire logs may even crack or break. If the latter happens, the obstruction can lead to even more soot.

• Is your exhaust vent or chimney blocked? These are two more things to look out for. While it may cause increased soot, it can cause larger issues as well. It’s best to contact chimney professionals if you notice.

• Check out the air-flow. You should be looking for yellow flames that are unobstructed. This type of flame indicates that minimal or no soot will occur. If a flame is looking for more air, it can produce more soot and needs some adjustment.

• Have you performed regular maintenance? Even though gas fireplaces require less maintenance than wood-burning fireplaces, they still require annual attention. This way, you’ll be ready for winter fires uninterrupted.
