It won't harm a gas fireplace if you have it on 24/7 so long as it is properly vented. However, there are some risks. While a properly sealed and vented gas fire should not cause a threat, there is always a chance, however slim, that a fault will lead it to emit carbon monoxide into the living area.
However, if the seal is deteriorating, or you have glass doors that open like a traditional wood-burning fireplace, then it is advisable to avoid running the gas fireplace for more than three hours to minimize the risk of carbon monoxide exposure.
You start smelling strange odors

1. Is it safe to leave a wood-burning fireplace on overnight? No, it's not safe to leave a wood-burning fireplace on overnight. The risks of house fires, carbon monoxide poisoning, and creosote buildup make it unsafe.
Gas fireplaces rely on consistent combustion to produce real flames and keep the fire burning for long periods of time. Overall, gas fireplaces are highly efficient when it comes to heating a room. Once a fire has been burning for some time, it's likely to heat a room rather quickly.
Gas combustion produces carbon monoxide, an odourless, colourless gas that can be deadly. Even small leaks can build up to dangerous levels, especially while asleep. Symptoms of carbon monoxide poisoning include headache, dizziness, nausea, and shortness of breath.
Signs of a carbon monoxide leak in your house or home
Sooty or brownish-yellow stains around the leaking appliance. Stale, stuffy, or smelly air, like the smell of something burning or overheating. Soot, smoke, fumes, or back-draft in the house from a chimney, fireplace, or other fuel burning equipment.
The main danger from a gas fireplace is carbon monoxide, a harmful gas we can't see or smell. It's important to have detectors in your home for this. A good venting system helps to keep the air fresh in your home when using a gas fireplace.
There is a risk of carbon monoxide poisoning when you sleep in a room where a conventional coal or gas fire, a log burner, a cooker, or a back burner is left on overnight. You cannot feel the early symptoms of carbon monoxide poisoning, so it is important that you protect yourself.
There are a few things that can happen if you leave your gas fireplace on for too long. House fires are a possibility, especially if your fireplace isn't properly monitored. Running your fireplace for too long can also cause a gas leak.
Englund suggests starting by opening windows in the room where the fireplace is located, and perhaps opening some other windows on the same floor to create cross-ventilation. Turn on overhead ceiling fans or other ventilation if possible.
The biggest risk of leaving a gas fireplace burning all night would be a house fire or gas leak. A gas leak due to failing components would mean toxic and deadly fumes pouring into the house and this is why each family that owns a fireplace should have working smoke alarms and carbon monoxide detectors.
One of the most common problems faced by homeowners with gas fireplaces is the pilot light going out or not staying lit. The pilot light is a small flame that ignites the gas burner, which produces the heat for your fireplace — if the pilot light goes out, your fireplace won't work.
Leaving a fireplace burning overnight can present risks and hazards. Some of these include: Risk of fire: If the fireplace is not properly maintained or if there is an excessive buildup of fuel, it is possible for a fire to start. Risk of carbon monoxide poisoning: Carbon monoxide is produced when fuel is burned.

Yellow or Brown Stains. Appliances that run on combusting fuel should have unobstructed ventilation. If you notice brownish-yellow or soot-like stains around a heater or gas fireplace, there may be combustion issues. This can be a sign of a carbon monoxide risk.
The combustion process in ventless gas fireplaces releases various byproducts, including carbon monoxide (CO) and nitrogen dioxide (NO2), directly into the indoor environment. These byproducts can have detrimental effects on indoor air quality and, consequently, on the health and well-being of occupants.
