Decorative gas appliances, also known as gas log sets, can enhance any living space. Coupled with a modern design, a gas stove can look as natural as a real wood-burning fireplace, but without the smoke and ash.
Below are some frequently asked questions about gas fireplaces and gas log set.
Do Gas Fireplace Logs Need to Be Vented?
There are two distinct options for gas log set: vented and ventless (vent-free). Vented gas log sets need to be vented through a fully functional chimney. Ventless gas log sets do not require venting, just an approved fireplace.
Vented Gas Log Sets
Vented gas logs must be vented through a functional chimney to move all combustion by-products outside. Vented gas logs produce the most realistic flames, but give off less heat than ventless logs, mainly because the chimney flue must be open when the fireplace is in use. That's why vented logs are often considered decorative appliances, so if aesthetics are your number one consideration when renovating your fireplace, a vented unit may be your best option.
Vent-free Gas Log Sets
Ventless gas logs do not require any special vents to use, just an approved fireplace. Thus, these units can be used in existing chimney flue closed fireplace installations or installations without a chimney at all. A ventless gas log is the best choice for heating because all the heat is put back into the room rather than lost through the chimney. Although uncommon, ventless fireplaces are prohibited in some states and jurisdictions, so be sure to check your local building codes before installing a ventless fireplace or gas furnace.
