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. See similar questions...

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.

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. See similar questions...

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. See similar questions...

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

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. See similar questions...

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. See similar questions...

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. See similar questions...

Vent free does not require a flue while direct vent has a flue which must vent outside through a wall or through the roof. Direct vent unit also requires a fixed glass front while vent free unit prohibits a glass front. See similar questions...

B-vented gas fireplaces require a special gas-only chimney that terminates above the roof (like a furnace). They install quickly and easily using a compact vertical vent, which exhausts burned gases from the living area effectively to the outside through the vent. B-vent fireplaces come in a variety of affordable models and styles, including multi-side and see-through. See similar questions...

Direct-Vent Fireplaces are ideally suited for today's energy-efficient, tightly constructed homes. The flames burn in a sealed combustion firebox, so the room air does not come in contact with the flames. The sealed firebox requires the fireplace to draw outside air to the fire for combustion. This is accomplished by using a coaxial pipe system which is actually a pipe within a pipe. See similar questions...

B-Vent fireplaces (sometimes called Top Vent or Natural Vent) draw air into the combustion chamber from inside the home. This fresh air is mixed with gas and burned in the fireplace. The fireplace exhausts the byproducts of combustion outside of your home using a dedicated B-Vent flue pipe. Although fresh air is used from inside your home, products of combustion are never vented into your home. Back to Top See similar questions...

Often, noise in Type B gas vent is caused by the relative movement of parts in the system with adjacent parts, with part of the structure, or because of additions or changes to the parts and/or system. If installed according to Hart & Cooley's installation instructions, the Type B gas vent is designed to accommodate the expansion and contraction due to heating and cooling which occurs within the system.

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. See similar questions...

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. See similar questions...
