“Fully Vented” gas logs must be burned in a fireplace that is capable of burning real wood and must be burned with the damper open. The reason for this is that they do not burn the gas cleanly and create exhaust that is very similar to burning a real wood fire. This exhaust needs to be able to go up the chimney.
Ventless fireplaces fueled by gas or propane rely on indoor air for combustion, and they exhaust a low level of their combustion gases into the room in which they’re located. A chimney or flue isn’t necessary. The risk to your health is a long-standing and ongoing debate.
Also Know, are vented gas fireplaces efficient? Vented Gas Fireplace Efficiency Two-pipe models offer efficiency ratings of 70 percent to 85 percent, while single-pipe units offer around 50 percent efficiency, according to the This Old House website. Single-pipe models are also known as “B-vent” gas fireplaces.
Also to know, what is the difference between a vented and unvented gas fireplace?
Vented gas logs burn like a real wood fire with a yellow flame that produces smoke. They must be burned in a wood burning fireplace with the damper open, so smoke goes up the flue along with most of the heat. Ventless (vent-free) gas logs burn cleanly with a lower flame that does not smoke.
Are vent free fireplaces dangerous?
Carbon Monoxide and Other Dangerous Gases Of all the dangerous gases, carbon monoxide is the most dangerous and the most notorious. Excessive water vapor being emitted from your vent–free gas fireplace can cause your wallpaper to peel, as well as other structural damage.
Which is better vented or ventless gas fireplace?
It all depends on your needs, but vented sets have a more realistic flame and can be used in an existing real wood fireplace, while ventless logs are more efficient. A gas fireplace makes a great alternative for homeowners looking for a supplemental heat source that also provides a beautiful ambience.
Do ventless gas fireplaces give off carbon monoxide?
As a result, “When they’re running correctly, ventless gas fireplaces do a pretty good job,” says Bailes. Incomplete combustion creates the dangerous molecular byproduct carbon monoxide (CO)—an odorless gas that causes brain damage and even death at high-enough exposure levels.
How can you tell if your gas fireplace is vented?
How to Tell If Your Gas Logs Are Vent-Free Inspect the logs. All vent-free logs are firmly attached to a U-shaped burner and cannot be moved. Follow the gas line from beneath the logs to where it disappears in the wall or floor. If the gas is merely contained by a simple gas line, then the logs are vent free. Turn on the fireplace.

Can you get carbon monoxide poisoning from a gas fireplace?
Yes, gas fireplaces are one potential cause of carbon monoxide poisoning. An improperly maintained or ventilated gas fireplace, however, can result in incomplete combustion, creating carbon monoxide, and causing this toxic gas to linger—putting those inside at risk of carbon monoxide poisoning.
Are gas fireplaces safe?
Gas fireplaces are safe. But as with all gas appliances, they do produce carbon monoxide. If something goes wrong, carbon monoxide put the home’s occupants at risk. Therefore, carbon monoxide detectors are a critical part of gas fireplace safety, even if you don’t use the fireplace often.
What is the difference between a gas fireplace and a gas insert?

Should gas fireplace smell?
No, it is not normal for a gas fireplace to give off a strong smell for this long of a time. The strong “urine” smell could be urethane insulation that is too close to the firebox or vent pipe. Or if you are running on natural gas, it could be the mercaptan odorant in the gas which is leaking.
Can I have a gas fire without a chimney?
What is a flueless gas fire? Having a flueless fire installed basically means that your fire will not have a flue. With no chimney or any pipes, the flueless fire will operate without both and the emissions from the fire will leave from the top or front.
How do you vent a gas fireplace without a chimney?
