The new truth about gas fireplace odor and headache

by CCAuthor

Some homeowners experience a gas fireplace odor that gives them a headache.  The first place to check is the vent free gas logs installed.  [Disclaimer: we are not medical professionals and this is for information only.  Please check with your doctor for symptoms related to gas fireplace odor & headache.]  Let’s talk about the ways that the gas can cause issues.

Most of the time, it is related to unburned natural gas or propane escaping from the firebox or burner.  The connections to the supply are not tight is the first cause.  Use a bubble mixture and spray on the connections to see if any gas is escaping.  Bubbles show up here for a leak.

Secondly, incomplete combustion from a gas log set can cause this smell.  Check the orifices on the burner system for clogs and obstructions.  The openings get stopped up and not enough gas comes out to burn but does escape into the air.

Vent free gas logs not set up correctly can cause odor resulting in headaches. Monessen Stony Creek Vent Free Logs shown here for an example.

When searching for gas fireplace installation near me, ask about the complete combustion test.  The orifices are checked for clogs, the logs are properly set and the connections are check for leaks.

It’s about the design


A well-designed gas fireplace system not only focuses on these maintenance details but also ensures that the byproducts of combustion are efficiently vented outdoors. This design feature is crucial because it helps prevent odors from accumulating indoors, keeping the air fresh and pleasant.

A properly installed fireplace and chimney should release 100% of combustion byproducts to the outdoors. This is vital not just for maintaining pleasant indoor air but also for ensuring the health and safety of your household. Therefore, a gas fireplace odor giving a headache is not something to avoid. By emphasizing both design and routine checks, you can enjoy years of reliable service with minimal air quality issues.

Therefore, a gas fireplace odor giving a headache is not something to avoid.  Our body tells us when it is not happy.  This is the way we are created. 

However, if you notice a gas smell from your fireplace, it’s crucial to take immediate action. Gas odors should never be ignored, as they can signal serious issues that could lead to dangerous situations.

When to be Concerned

  • Gas Leak from Plumbing Assembly: A leak can occur whether the fireplace is on or off. The accumulation of natural gas or propane in a confined area like a fireplace could lead to a life-threatening event, such as a fire or explosion.

  • Exhaust Spillage: Sometimes, gas odors arise from exhaust not properly venting through the flue. This can smell like a kitchen range left on too long. Such an issue indicates that your fireplace isn’t drafting correctly, potentially exposing you and your loved ones to carbon monoxide.

Why Immediate Action is Necessary

  • Health Risks: Exposure to gas or carbon monoxide can have serious health implications. Symptoms like headaches can be an early warning sign from your body that something is wrong.

Incorporating regular maintenance checks and addressing any unusual smells promptly ensures the safety and well-being of everyone in your home.”

Some questions answered

1. What is the role of the chimney in a fireplace system?

The chimney plays a vital role in safely directing combustion byproducts outside, which is essential for preventing unpleasant odors and maintaining healthy indoor air.

2. Why is it important for all byproducts of combustion to be released outdoors?

Ensuring all combustion byproducts are vented outdoors is crucial not only for keeping the indoor environment pleasant but also for safeguarding the health and safety of those living in the home.

3. How does the design and installation of a fireplace affect indoor air quality?

A well-designed and properly installed fireplace, along with its chimney, ensures the efficient release of combustion byproducts outside, thus maintaining good indoor air quality over time.

Finally, it is a good idea to install a carbon monoxide detector when using a fireplace of any type.  Carbon monoxide is an odorless gas.  It is also heavier than air and will settle low to the ground.  Therefore, install the sensor about 2 to 3 feet up from the floor.

Ensuring Proper Drafting for Your Gas Fireplace to Prevent Odors

Keeping your gas fireplace drafting efficiently is crucial for maintaining a safe and odor-free home. Here’s how you can ensure it works correctly:

1. Regular Inspection and Cleaning

  • Schedule Annual Inspections: Have a professional inspect your fireplace yearly to check for blockages and ensure everything is functioning smoothly.
  • Clean the Flue: Soot and debris can block the flue, impeding proper exhaust. Regular cleaning is essential.

2. Proper Ventilation

  • Check for Obstructions: Ensure there are no obstructions in your chimney or vent pipe that could hinder airflow.
  • Install Ventilation Fans: If necessary, use fans to enhance airflow, particularly in areas with inadequate natural ventilation.

3. Monitor the Flame

  • Observe the Flame Color: A healthy gas flame should be blue. Yellow or orange flames could indicate a ventilation problem, necessitating immediate attention.

4. Use Carbon Monoxide Detectors

  • Install Detectors Near the Fireplace: These can alert you to dangerous levels of carbon monoxide, signaling that your fireplace isn’t drafting properly.
  • Regular Testing: Keep sensors in good working condition by testing them regularly.

5. Educate Yourself

  • Stay Informed: Understand how your specific model should function, as different fireplaces might have unique requirements.

By following these steps, you can significantly reduce the risk of gas odors in your home, thereby protecting your family’s health. Always consult with professionals if you suspect a drafting issue with your fireplace.

What Causes the Burning Plastic Smell in a Gas Fireplace After Months of Non-Use?

If you notice a burning plastic odor coming from your gas fireplace after it has been unused for a while, it is usually due to accumulated dust and debris. Over time, your fireplace becomes a magnet for household dust, pet dander, hair, and even skin cells. When you ignite it for the first time in the season, this buildup begins to burn away, leading to an unpleasant smell.

Here’s a breakdown of the process:

  • Dust Accumulation: During periods of inactivity, dust and other particles settle on the internal surfaces of the gas fireplace.
  • Initial Use: Upon reigniting the fireplace, these particles are exposed to high heat.
  • Odor Production: As the collected debris burns off, it releases odors similar to burning plastic.

This phenomenon is akin to what many experience when they first turn on a furnace after a long stretch of warm weather. While cleaning might seem straightforward, the interior of gas fireplaces can be challenging to thoroughly clean without professional help. Regular maintenance can help minimize these odors and keep your fireplace running smoothly.

Is it Normal for a Newly Installed Gas Fireplace to Emit an Odor?

Yes, experiencing an unusual smell when you first turn on your newly installed gas fireplace is completely normal. This scent often arises due to the manufacturing process. During production, various components like lubricants and paints are used, which can leave behind residues.

When the fireplace is initially operated, these residues burn off, producing an odor that some describe as similar to burning plastic. This is a temporary effect and should dissipate after the unit has run for a while.

If you notice the smell lingering for an extended period, it might be a good idea to ensure that all packaging materials were properly removed and that the fireplace was installed correctly. Always consult your user manual or a professional if you have concerns about safety.
