When it comes to your gas fireplace, you expect it to provide warmth and comfort during the colder months. But what happens when strange smells start emanating from your fireplace?
If you’ve noticed an odd smell coming from your gas fireplace, you’re probably wondering what could be causing it. I’ve asked myself why does my gas fireplace smell on more than one occasion.
There are a few possibilities, some of which are more serious than others.
In this article, we’ll explore some of the most common causes of gas fireplace smells, what you can do to fix them, and how to prevent them from happening in the first place.
So, read on to learn more about why your gas fireplace might emit strange smells – and what you can do about it.
1. Gas Fireplace Smells Like Gas When Burning
You can identify gas smells by their unique odor. When burning, gas smells like sulfur or rotten eggs. If you smell this while your fireplace is in use, it’s a sign that there’s a problem with the gas line.
Additionally, it could mean the valve isn’t opened all the way, which would cause incomplete combustion. This could damage your fireplace and release carbon monoxide into your home.
While it might be normal to experience strong gas smells after installing your gas fireplace for the first time, you should still contact a professional to inspect the unit.
How to Get Rid of the Gas Smell?
- If you smell gas, open a window and leave the area immediately. Do not turn on any lights, as this could create a spark that ignites the gas.
- Call your gas company or fireplace professional to inspect the unit and find the source of the problem. They’ll be able to properly assess and fix the issue so you can safely use your fireplace again.
2. Gas Fireplace Smells Like Chemicals
So, why does my gas fireplace smell like chemicals?
The answer is twofold. First, when you light a gas fireplace, you may notice a faint smell of chemicals; this is normal and should dissipate quickly.
However, if the chemical smell lingers or gets stronger, it could indicate that the unit isn’t burning correctly. Incomplete combustion can produce harmful chemicals, like carbon monoxide, which can harm your health.
Debris in your gas fireplace can also lead to your unit producing chemical smells when burning. The main culprits are debris like paint, plastics, or insulation that can release harmful chemicals when burning.
How to Get Rid of the Chemical Smells from Your Gas Fireplace?
Usually, the chemical smells associated with gas fireplaces should dissipate quickly. If the smells linger, however, you may need to take some action.
Here are a few things you can do to get rid of chemical smells in your gas fireplace:
- Hire professional service for your fireplace. They can inspect the unit and make sure it’s burning correctly.
- Clean your fireplace regularly. This will help remove any debris that could be causing the chemical smells.
- Use a good quality gas fireplace cleaner. This will help remove any soot or debris causing the smells.
- Make sure your gas fireplace is adequately ventilated. This will help to disperse any fumes and odors.
If you follow these tips, you should be able to get rid of any chemical smells coming from your gas fireplace.

3. Gas Fireplace Smells Like Burning Plastic
Because they come from manufacturing, gas fireplaces have lubricants, paints, and other finishing procedures that leave debris in the passageway, resulting in an unpleasant stench that some people compare to burning plastic.
Burning plastic smells irritating, and you can quickly identify it. If you notice this smell coming from your gas fireplace, it’s essential to take action immediately.
How to Get Rid of the Plastic Smell
There are a few things that you can do to get rid of the burning plastic smell:

4. Gas Fireplace Smell Like Kerosene
Kerosene smells like gasoline, which gives off a strong, unpleasant odor. As you may know, gas relies on a chemical reaction to produce heat and light, and this can sometimes result in the release of chemicals that smell like kerosene.
Therefore, a mild scent of kerosene around your gas fireplace is not unusual and generally nothing to be concerned about. However, if the smell is strong or persists, you should contact a qualified technician to inspect your fireplace.
In some cases, a strong kerosene smell may indicate a problem with the appliance itself, such as a cracked heat exchanger. In other cases, the problem may be with the ventilation system, allowing deadly carbon monoxide to enter your home.
Either way, it’s essential to have the situation checked out as soon as possible.
How to Get Rid of Kerosene-Like Smells from Your Gas Fireplace
There are a few things you can try to get rid of the kerosene-like smell in your gas fireplace:
- Check that all ventilation openings are clear and unobstructed.
- Inspect the gas line for leaks.
- Have a qualified technician inspect and clean the appliance.
If the problem persists, you may need to replace the fireplace.
5. Gas Fireplace Smells Like Burning Dust
When your gas fireplace accumulates dust and dirt, it can smell like burning dust when you turn it on. This is because the fire is burning off the dust and dirt.
Dust consists of tiny particles like skin cells, fabric fibers, and pet hair.
When these particles burn, they release a foul smell that can make your whole house smell terrible.
The best way to prevent this is to clean your gas fireplace regularly. This will help to remove the build-up of dust and dirt so that it doesn’t have a chance to accumulate and cause problems.
Ensure you contract a professional to inspect and clean your gas fireplace at least once a year to avoid smells. Doing so yourself can be ineffective and dangerous.
6. Gas Fireplace Smells Musty
We can describe a musty smell as stale, damp, or moldy, and it’s usually caused by moisture and mold, a common problem with gas fireplaces. If your gas fireplace smells musty, here are a few things you can do:
- Check for leaks: First, you’ll want to ensure there are no gas leaks. If you smell gas, open a window and get out of the house immediately. Then call your gas company.
- Check for moisture: Next, you’ll want to check for any moisture in the area around your fireplace. This could be from a leaky pipe, condensation, or high humidity. If you find any moisture, you’ll need to dry it up and fix the source of the leak.
- Clean your fireplace: Once you’ve taken care of any leaks or moisture, it’s time to give your fireplace a good cleaning. This will remove any soot, ashes, or dirt causing the musty smell.
- Use a dehumidifier: If you live in a humid climate or your home is particularly damp, you may want to use a dehumidifier in the room with your fireplace. This will help to remove any excess moisture from the air and should help to get rid of that musty smell.
If you’ve tried all these things and your gas fireplace still smells musty, you may need to call a professional. There could be a problem with your chimney or venting system that a professional will be able to identify and fix.
7. Gas Fireplace Smells Like Dead Animal
If you have a gas fireplace that smells like a dead animal, a few things could be the cause. First, ensure that the flue is open and no debris is blocking it.
If the flue is clear, the gas fireplace may smell like a dead animal because something has died in the fireplace. In this case, you’ll need to remove the animal and clean the fireplace thoroughly.
To do this, you’ll need to:
- Shut off the gas to the fireplace.
- Remove any ashes and debris from the fireplace.
- Wear protective gear.
- Locate the dead animal and remove it from the fireplace.
- Clean the area where the animal was with a disinfectant.
- Once the area is clean, you can turn the gas back on and relight the fireplace.
Removing a dead animal from a fireplace is not a pleasant task. If you’re not comfortable doing it yourself, you can hire a professional to do it for you.
Moreover, it can be risky if you’re not careful. So, if you’re unsure how to do it, it’s best to leave it to the professionals.

9. Gas Fireplace Smells Like Urine
Nobody likes the smell of urine, but it might be due to a few different things if your gas fireplace smells like this.
The strong “urine” stench may be due to too much urethane insulation or a faulty vent pipe connection. It could also be a mercaptan leaking, an odorant in natural gas.
How to Get Rid of Urine Smell from Your Gas Fireplace
The best way to get rid of the urine smell from your gas fireplace is to have it professionally inspected and cleaned.
If you suspect your vent pipe connection is the problem, you can try tightening the connection or replacing the pipe. If this doesn’t work, you may need to replace the entire gas fireplace unit.
10. Gas Fireplace Smells Like Propane
Propane is a hydrocarbon, and as such, it has a distinctive smell. The smell of propane is often described as similar to rotten eggs. If you notice a propane smell coming from your gas fireplace, it is crucial to take action immediately.
There are a few reasons your gas fireplace might smell like propane. It could be that there is a leak in the propane supply line.
Alternatively, the problem could be with the fireplace itself. If you suspect a problem with the fireplace, you should contact a qualified technician for assistance.
If you smell propane but cannot determine the source of the leak, it is essential to evacuate the area immediately and call your gas company. Do not attempt to find the source of the leak yourself. Propane is highly flammable, and even a tiny spark could cause an explosion.

Finally, your gas fireplace may smell like car exhaust if there is a problem with your chimney or flue. A car exhaust emits a distinctive smell many people can recognize immediately.
If your gas fireplace smells like car exhaust, you’ll notice a strong, unpleasant smell that may make you nauseous.
The smell of car exhaust can be caused by several things, including a blocked chimney or flue, a cracked chimney liner, or a problem with the draft. Unlike propane, you can try to find the source of the smell of car exhaust and fix it yourself.
If your gas fireplace smells like car exhaust, you should:
