Why Gas Logs Making Fluttering Noise?
The primary reasons for fluttering noise in gas logs is an airflow imbalance, which can disrupt the combustion process, leading to irregular sounds.
A dirty burner or logs can obstruct the gas flow, causing fluttering noises as the gas struggles to ignite properly. Low gas pressure can also contribute to incomplete combustion, resulting in an unsettling sound.
Reasons for Gas Fireplace Making Fluttering Noise
1) Airflow Imbalance
An airflow imbalance is one of the primary culprits behind fluttering gas logs. If the airflow isn’t balanced correctly, it can lead to irregular combustion, resulting in a fluttering sound. Ensure that the damper and vents are open and unobstructed.
2) Dirty Burner or Logs
Over time, dust and debris can accumulate on the burner and gas logs, disrupting the even flow of gas. Cleaning the burner and logs regularly can eliminate this issue.
3) Low Gas Pressure
Inadequate gas pressure can lead to incomplete combustion, causing the ventless gas fireplace making fluttering noise. Contact your gas provider to ensure your gas pressure is within the recommended range.
4) Thermocouple Issues
A malfunctioning thermocouple can cause intermittent gas flow, leading to fluttering sounds. Inspect the thermocouple and replace it if necessary.
5) Thermal Expansion and Contraction
Gas logs undergo rapid temperature changes during operation. As they heat up and cool down, the metal components can expand and contract, resulting in minor movements that could lead to a fluttering noise.
6) Loose Components
Over time, various components of the gas logs, such as logs, grates, or decorative elements, can become loose due to vibrations or regular usage. These loose parts may move slightly when the gas fireplace operates, causing the fluttering sound.
How to Fix Fluttering Noise in Gas Logs
- Gently clean the burner and gas logs using a soft brush or compressed air. Ensure there is no debris hindering the gas flow.
- Verify that the gas pressure is within the manufacturer’s recommended range. If it’s too low, contact your gas provider for adjustments.
- A flickering pilot light can contribute to fluttering sounds. If the pilot light is unstable, it might need cleaning or realignment.
- Ensure the damper and vents are open and balanced to allow proper airflow. Adjusting the damper often alleviates fluttering noises.
- Regular maintenance by a qualified technician can address underlying issues and prevent future occurrences of fluttering noise.
Preventing Gas Fireplace Fluttering Noises
- To prevent your gas logs making fluttering noises, schedule annual maintenance for your gas fireplace to keep components clean and in optimal condition.
- Invest in high-quality gas logs less likely to accumulate dust and debris.
- Ensure your gas fireplace is installed correctly, with attention to venting and gas line connections.

FAQ
Why gas fireplace making noise when on?
A gas fireplace may make noise due to popping from igniting gas, air trapped in the gas lines causing hissing, the fan producing whirring sounds, or expansion and contraction of materials leading to clicking. Inconsistent gas pressure can also create irregular combustion noises.
Why gas fireplace pilot light making noise?
A gas fireplace pilot light may make noise due to a fluttering sound from an oversized pilot jet, which increases gas flow and creates a louder flame. Other causes include a long pilot flame or gas pressure issues, leading to roaring or hissing sounds. If the noise persists, it’s best to consult a professional for inspection and adjustments.
Is it normal for gas fireplace to make noise?
It is normal for a gas fireplace to make some noise, such as popping or clicking from metal expansion. However, excessive or unusual sounds may indicate issues. Hissing or roaring could signal a gas leak, which is dangerous and requires immediate attention. Buzzing may result from gas flow restrictions, while whistling can indicate vent obstructions or incorrect gas pressure.
