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.

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.

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.

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

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.

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.

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.

A faulty draft needs to be corrected whether you are burning wood or natural gas. One solution would be to install a direct-vent product rather than one that uses the existing flue.

Yes, providing your model has a standing pilot light or our patented IPI System, which works on a battery back up of 2 D cell batteries. If you have a fan or a remote control option, they will not work without power, but the appliance itself will burn and provide heat. (If you have a remote control, you may need to operate the appliance with the ON/Off switch in the control area of the appliance).

These type of fireplaces do not have a sealed combustion chamber and relies on the bouyancy of hot gases to vent effectively. They must be installed either with an existing chimney that meets the local building code standards or they can be installed using a B vent which is a vent pipe that must be installed to the same parameters of a masonry chimney but can be enclosed in combustible material. They draw air (oxygen) necessary for combustion from the area surrounding the fireplace.

Have your chimney checked or cleaned every year. Chimneys can be blocked by debris. This can cause CO to build up inside your home or cabin. Never patch a vent pipe with tape, gum, or something else. This kind of patch can make CO build up in your home, cabin, or camper. Horizontal vent pipes to fuel appliances should not be perfectly level. Indoor vent pipes should go up slightly as they go toward outdoors.

Operating cost will vary by region, by gas utility, and by fuel type. Based on national averages, a natural gas fireplace consuming 27,000 BTUs/hr will cost less than 20 cents/hr to enjoy. LP units run slightly higher. Your monthly gas bill should include your exact cost per "therm" (100,000 BTUs). Based on this rate, and the BTU input listed on the rating plate on your appliance, you can calculate the cost for your area.

Vent-free logs are rated as a heating appliance and do not require venting to the outside. Vented logs are rated as decorative and require venting to the outside. Heatmaster vent-free logs are CSA certified both vent-free and vented.

They can burn one or the other, but not both. You need to be sure the gas hearth applicance you have is set up for the type of gas fuel you intend to burn. Conversion kits are available which will allow a unit to be changed to match the proper fuel type.

Although the frequency of your fireplace servicing and maintenance will depend on use and the type of installation, you should have a qualified Mr. Fireplace service technician perform an appliance check-up at the beginning of each heating season.

No! The beauty of Regency Direct Vent technology is that you do not necessarily need to go up through your roof to terminate the venting. All you need is proximity to an outside wall, the distance to which depends on the model you choose. Not only does this make installation more flexible, but it also keeps the costs down. And with our sleek and attractive patented AstroCap horizontal termination cap, you won't be cluttering up the outside of your home either.
