Gas Fireplace Troubleshooting

Pilot Light 
The pilot light for your gas fireplace is an ignition source. If your fireplace won't turn on, it may be a simple matter of the pilot flame having been blown out. To find out, simply open the vent. You will be able to determine whether or not the small flame is out. If it is, simply re-light the pilot with a match or a lighter to see if the fireplace turns back on. 
Alternatively, if the flame reignites initially but the pilot won't stay on, there are more in-depth factors to investigate surrounding the pilot light. 

Gas Fireplace Soot Abundance 
Soot buildup is normal on vented gas logs, but not on vent-free units. In general, propane-powered fireplaces will produce more soot than natural gas fireplaces. If you notice excess soot build-up, here are a few common culprits. 
Improper Airflow: Ensure that there is a proper ratio between the flame’s gas and oxygen; a flame that has too much gas will produce more soot. Follow the manufacturer’s instructions to increase oxygen and decrease gas flow. Note that this may cause the flame to appear more blue than orange. 
Chimney: Make sure your chimney is clean and clear of obstructions. Common obstructions include bird nests, leaves, twigs, and branches. 
Improperly Arranged Firebox: Make sure that the embers and logs in your firebox are arranged correctly and according to manufacturer specifications. If the logs are misplaced, they disrupt the flow of the flames, causing soot to be deposited. 
Clogged Burners: Clogged or broken burners can also cause excess soot build-up. Ensure that they are clean and in working condition. 

Why Is My Gas Fireplace Making A Noise? 
Gas fireplaces will make some noise as part of their normal operation. However, there may be unusual noises caused by external issues. 
Rumbling or Roaring Noise: This could be an issue with your pilot light. Adjust the flame to see if this solves the issue. Also, ensure that your burners are clean; dirty burners can also cause this kind of sound. 
Grinding or Shrieking Noise: This could be an issue with your blower. 

Why Is There Moisture/Condensation on the Glass? 
When you start your fireplace, you may notice condensation on your glass door as water vapor in the air inside the firebox evaporates. This should dissipate as the fire heats up. There may be some buildup over time of condensation residue, but this is easily wiped away. 
Many of these tips and diagnoses for these common gas fireplace problems can be done by yourself. However, if you ever feel like you’re in over your head, or you suspect there is a serious problem like a gas leak, please call a professional to service your unit. 

Why Does My Gas Fireplace Smell? 
If your fireplace is new, there may be what is known as “off-gassing,” caused by residual factory paints burning off. This is harmless and should pass after a few fires. If the smell persists, check that your chimney is not obstructed and is cleaned. If you suspect the smell is gas, and the pilot light is on, you may have a gas leak. Shut off the fireplace, ensure your home is vented, and call your gas company or a professional technician.
