No. Direct vent fireplaces use a sealed glass front to completely isolate combustion gasses and moisture from your home. This is especially important in new construction homes that are built very tightly to comply with today's energy codes. Ventless fireplaces are designed to expel combustion gases and moisture directly back into the room. Ventless or unvented are illegal in many states and municipalities.

A wood-burning fireplace is totally vented. For a complete explanation of these terms see our Venting page.

Cabinets are boxes that extend about 18" from the wall. Mantels are wood frames that only extend about 4" - 6" from the wall. B-vent cannot have a cabinet. A b-vent fireplace must be installed in the wall, allowing all the piping to be hidden. You may then use a mantel. Vented gas logs can only be used in a wood-burning fireplace. A coal-burning fireplace is too shallow. Vented gas logs are not recommended for a stove due to safety concerns.

Direct-vent products derive their combustion air from outside of the home. This is often achieved through either side by side vent pipes or pipes designed with one pipe inside another. One of the two pipes brings in the fresh air and the other expels exhaust gases. Direct-vent products are generally considered to be more efficient than b-vent models.

These terms refer to how a gas appliance takes in the air it needs to burn gas. A B vent unit draws air from inside the home, through ports in the firebox itself. A Direct Vent unit draws air through a pipe from outside the home, into a sealed firebox. Direct Vent models are usually more efficient and safer for today's airtight homes, since they do not use inside air or cause a conflict with range hoods and bathroom fans circulating the same air.

A direct vent fireplace or insert is the best hearth choice when it comes to protecting the air inside your home that you and your family breathe. A direct vent fireplace is designed with a sealed glass that keeps gases such as carbon monoxide and excess moisture from entering your home. This design uses air from outside your home to fuel the fire rather than pulling from air inside.

Direct vent technology is available in single-sided or multi-sided fireplaces, as well as freestanding and insert models. They use a sealed combustion chamber that vents out the back or top, to the outside. This allows easy installation of a beautiful and realistic fireplace without the expense of a traditional chimney system. Because no room air is used for combustion, direct vents are especially efficient (up to 70+%) and will not alter the quality of your room air.

All gas fireplaces need a constant supply of fresh air in order to operate. Direct Vent fireplaces have a sealed, glass-fronted combustion chamber that keeps the byproducts of combustion out of the living space. Air is drawn into the firebox from outside the home using a special co-axial flue pipe system. This 'pipe within a pipe' also exhausts the flue products outside the home. Direct vent fireplaces offer good efficiency because they don't steal heated air from the living space. Back to Top

Answer: A direct-vent fireplace is a sealed combustion appliance where air is drawn from outside and all smoke and vapor is vented directly outside.

e are three different terms that represent three different ways of 'venting' a gas fireplace, that is, to supply combustion air to the fireplace and evacuate combustion gases out of the house. In Australia, the term 'open flue' is commonly used instead of 'B-vent'. B-vent means a traditional type 'B', 4' (102mm) rigid pipe used to evacuate combustion gases. It can also be a certified flexible aluminium liner of the same diameter, inserted into an existing masonry chimney or a prefab chimney.

A direct vent fireplace is a sealed unit that gets its combustion air from outside of the home. The direct vent pipe can vent either vertical or horizontal and can use elbows to go around obstructions. B-Vent units use combustion air from the home but can be enhanced with an outside air kit. B-Vent pipe must terminate vertically and you must follow the installation instructions of the B-Vent manufacturer.

A b-vent fireplace is the least efficient venting option and can be vented horizontally or vertically. Direct venting is the most efficient; some are even "heater rated" and can be vented horizontally, vertically or both.

Answer: A B-Vent fireplace draws air from inside the home through ports in the firebox itself. A Direct Vent unit draws air from outside through a pipe into a sealed firebox.

A B-vent must be vented vertically and uses air from inside the home to provide oxygen to the fire. A direct vent uses a sealed glass front and pulls all of its combustion air from outside the home. This is important in new construction or well insulated homes that are tightly built. Direct vents can be vented vertically or horizontally through an exterior wall. Direct vents are more efficient than B-vents since they do not take any air out of your home.
