Blazing Ventless Gas Fireplace
The ventless gas fireplace is the most efficient of all gas fireplaces because of the high amount of heat and low emissions it produces. You may be happier with a vent free gas fireplace because it is usually built as a free standing gas fireplace and can create a beautiful focal point for your backyard. These vent free fireplaces are usually prefabricated outdoor gas fireplaces and you may be able to put one together over a weekend.
When you purchase your ventless fireplace it will come with a fire box, gas fireplace logs, and a glass enclosure. It burns natural gas and does not need to be vented. Ventless fireplaces operate at a higher temperature and thus produce more heat than vented fireplaces. In addition, they are more efficient because the heat does not go up the chimney. These fireplaces burn more cleanly and produce significantly few pollutants.
A Vent free fireplace does produce trace amounts of carbon monoxide. This is not an issue in an open area like a patio, but if you intend to use it on an enclosed porch, it is best to purchase an oxygen depletion valve. This valve shuts off the fireplace if the oxygen drops below a certain value. Note that ventless fireplaces also produce a certain amount of water and can cause the air to become moist. If this is a problem on an enclosed porch, you can purchase a dehumidifier can remove the excess water.
Before installing a ventless gas fireplace, check your local building codes. In some states this type of fireplace is not legal, and in other states there are very strict codes on how to use them. Note that if you put a ventless insert into a fireplace, according to most codes, it must be a working fireplace.
Vent Free Gas Fireplace Logs
Gas logs come in two varieties: vent free and
vented gas logs
. Vent free gas logs are used with your ventless gas fireplaces. Their main advantage is they produce more heat and create few pollutants. These logs don’t look as natural as the vented gas logs. Gas log sets come with a grate, logs, and a burner. These logs are made from cement, ceramic clay, or ceramic fibers. Generally, ceramic fiber logs are used for ventless logs, however, ceramic clay logs may be used as well.
The gas fireplace logs will be installed with a safety pilot kit that consists of a pilot light and a shut off valve. The pilot light starts the fire automatically and may be left on all the time or re-lit every time you want to start a fire.
