Add style to your masonry fireplace with a new set of glass doors and vented gas logs. Vented gas logs will give the illusion of real wood burning in your fireplace, without the hassle of cleaning up the mess. Gas logs will not wear away over time, and will burn the same way time and time again.
Vented gas logs use the natural draft of your fireplace to exhaust the byproducts of combustion (carbon dioxide and water) outside. In Massachusetts, it is required that the damper be permanently fixed open or completely removed prior to installation. As a result, vented gas logs are not efficient as a source of heat, and are used more to add ambience to your home.

Because the damper must be fixed open, we highly encourage the inclusion of a glass door with a gas log setup. All glass doors that Anderson Fireplace uses are customized to the size of each individual fireplace. They are designed to help minimize air escaping through the flue when the gas log is not being used.
Like the gas logs mentioned above, modern gas media gives you the flair.
Are vented gas logs a good source of heat for my room?
Vented gas logs are primarily designed to add gorgeous ambiance and the illusion of a real wood-burning fire to your home, rather than acting as a primary heat source. Because they use the natural draft of your chimney to safely exhaust combustion byproducts outside, much of the heat naturally goes up the flue. If your main goal is heating efficiency, we typically recommend a direct-vent gas insert instead.
Why is it recommended to install custom glass doors with vented gas logs?
In Massachusetts, building codes require that the damper be permanently fixed open or completely removed when vented gas logs are installed to ensure safe ventilation. Because the damper remains open, your home’s heated or cooled air can escape up the chimney when the fireplace is not in use. Custom-fitted glass doors help minimize this air loss, keeping your home energy-efficient and secure.
What are the Massachusetts state requirements for installing vented gas logs?
Safety is our top priority. The state of Massachusetts mandates that any installation of vented gas logs must include permanently fixing the fireplace damper in the open position, or removing it entirely. This guarantees that all combustion byproducts, like carbon dioxide and water vapor, exhaust safely outside your home. Our expert team ensures your installation is 100% compliant with all local codes.
Do vented gas logs require a lot of maintenance?
One of the biggest advantages of vented gas logs is their low maintenance! Unlike a traditional wood fire, there is no ash to sweep, soot to aggressively scrub, or wood to chop and store. Your gas logs will not wear away over time and will burn with the same beautiful, consistent flame time and time again.
