What is the difference between a Direct Vent and B-vent?
These terms refer to how a gas appliance takes in the air it needs to burn gas. Direct vent models refer to how a fireplace draws combustion air from the outdoors and returns the combustion exhaust back to the outside of the house eliminating the need for a standard chimney system. A glass panel in direct vent models is critical for keeping the combustion system sealed from the home, maintaining high efficiency and indoor air quality. A B-Vent modeled fireplace draws the combustion air from inside the home and vents combustion exhaust to the outdoors.
