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.
Unflued gas heaters require ongoing ventilation to external spaces to allow fresh air to fuel the burner and discharge combustion products.
Slightly opening a window near your fireplace helps limit smoke and avoid buildup of carbon monoxide.
Glass doors are beneficial on both gas and traditional fireplaces. They add a finishing touch to your fireplace look and can also help keep small children and pets out. It's important to remember that your glass doors should always remain open when burning gas logs.

Answer: It is not safe to leave a gas fireplace on overnight or while sleeping.
It's vital to keep both your fireplace doors and chimney flue closed when a fire is not burning and open when a fire is burning. Hot air rises, and when the heat that was generated from the fire finds its way up and out of the chimney, it tends to siphon all of the warm air in the room along with it.
One caution, though: Fireplaces with installed gas logs are required to have the damper open at all times. That's either because a pilot light is constantly burning under the logs or because the homeowner might forget to open the damper when he or she turns on the fire.

Does Opening Windows Help With Carbon Monoxide? Opening windows helps the carbon monoxide quickly leave your home (as does opening doors). However, don't leave your exit path when getting out during this emergency to open as many windows as you can.
Ignoring firebox damage puts your home and family at risk of fire and carbon monoxide poisoning. Also, if the cracks are large enough, burning embers can come through and contact the wall behind it. Another concern over cracks in the firebox is the chance that gases and carbon monoxide can leak out into your home.
Key points about carbon monoxide poisoning
Most CO exposures happen in the winter. A common source is unvented space heaters. Symptoms of CO poisoning include headache, dizziness, weakness, nausea and vomiting, rapid heartbeat, shortness of breath, seizures, chest pain, disorientation, and loss of consciousness.
While all this might seem like a minor issue, getting it wrong can have a notable impact on your fuel economy; using AC can increase your fuel consumption by as much as 10% but opening the windows at higher speeds can increase fuel consumption by as much as 20%.
Always ensure that the room in use is well-ventilated. If it becomes stuffy, open windows and doors to allow fresh air in immediately. Unvented heaters shouldn't be used in small-enclosed areas, especially bedrooms because of the potential for a build-up of carbon monoxide.
A direct vent gas fireplace or fireplace insert has a sealed piece of tempered or ceramic glass on the face of the fireplace. As a result of normal operation of these fireplace products, the glass front will become very hot. It is not unusual for the glass to reach sustained temperatures of over 475° Fahrenheit.
In short, you cannot remove the glass panels on your direct vent gas fireplace. However, some gas fireplaces can operate even without a glass in place.
You are unable to see or smell the gas, but it can nevertheless cause serious injuries and even death. 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.
A vented gas log fireplace expels carbon monoxide fumes from your home through the chimney or a direct flue vent. In addition, it has a sealed glass front to prevent toxic fumes from leaking into your home. Therefore, you can safely operate a vented gas log fireplace continuously.
All gas fireplaces should have a protective screen over the glass. Screens reduce risks of serious burns by creating a barrier that prevents skin from coming into direct contact with the hot glass. Keep in mind, however, that screens can also retain heat, so touching them isn't advised.
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. The type of gas fireplace you have is likely to affect the fireplace's ability to heat a room efficiently.
When you aren't using your fireplace, it should be closed to prevent heated and cooled air in your home from escaping. A closed damper also stops cold drafts from coming down the chimney. When you are using your fireplace, it needs to be open so that smoke can vent outside.
