Gas fireplaces normally come in two types – the vented and unvented. The vented type is the traditional one as it vents outside similar to a fireplace that burns wood. The vent free type is different in that it uses unvented gas logs which create lesser carbon monoxide emissions compared to using wood or gas. They’re also known as vent free and unvented fireplace.

A ventless fireplace is called as such because it does not require the installation of a chimney. With no chimney, it only means that the heat generated by the fireplace circulates entirely in the home. This makes the vent free fireplace more energy efficient compared to the traditional types. Installing it is not a difficult process as it can be placed anywhere.

For ventless fireplaces, unvented gas logs are required. These logs have become popular in recent years with their sales going up to the level of the vented logs. Gas logs that are unvented are cheaper and usually come with an oxygen depletion sensor (ODS). This sensor is meant to turn off the gas even before the level of carbon monoxide in the room becomes too high and dangerous.

Since burning is controlled through the sensor system, the carbon monoxide produced in the air as a result of the combustion process is lower. With the ODS, enjoying the warmth of a real fire is much safer and cleaner due to less pollution of carbon monoxide in the air.

Another benefit of a ventless fireplace is the absence of ashes and sparks. In addition, it has an easy control system allowing users to switch the appliance on and off either manually or by using the remote control. The buildup of thick yellow to brownish oily substance known as creosote which one experiences in wood burning is also avoided.

Extra care must be observed when installing a ventless gas log fireplace. Since unvented logs are capable of producing great heat, homeowners should ensure that all combustible materials are placed away from the fireplace. When in use, the fireplace doors should remain open and only allow the gas logs to burn for a few hours.

The only downside to the ventless gas log fireplace is the large amount of water vapor or moisture it creates. For this reason, manufacturers recommend homeowners to slightly open a window in the room when using the fireplace. This type is also not allowed for use in the bathroom and bedroom. Ventless gas fireplaces are ideal for short period usage and only as a supplemental heat source.

Homeowners should also be aware that unvented gas logs are not allowed in many states such as California, Alaska, New York, Utah, Massachusetts, Colorado, Montana and Minnesota. It is best then to verify with your local building codes before purchasing them. When buying your unit, make sure that it has the seal of the American Gas Association (AGA). Manufacturer’s instructions should strictly be followed when installing the fireplace for proper functioning and safety purposes.

A ventless fireplace can add beauty and warmth to any home. Be sure to compare prices on ventless fireplaces before buying.
