You can use ventless logs in a vented fireplace. If you do use a vent-free logs, you won’t have to open the damper since these logs don’t require venting.

In addition to carbon monoxide, ventless fireplaces also produce a high levels of water vapor. The increased level of water vapor in the home will increase humidity, increasing the risk of mold growth.
Do you need a chimney with ventless gas logs?
Ventless fireplaces are also known as “unvented” or “vent-free” fireplaces. They’re a type of fireplace that pipes natural gas or propane into a gas-burning unit. They’re actually designed to burn gas more efficiently than vented versions, so they produce less fumes and don’t require a flue or a chimney.
Which puts out more heat vented or ventless gas logs?
Ventless fireplaces are more energy efficient than vented fireplaces because no heat escapes up the flue, so you’ll save money on gas utility bills. A vented gas fireplace uses more gas to create the same level of warmth because some of its heat escapes through the flue.
What is the difference between vent-free and vented gas logs?
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.
