There are three main styles of gas fireplaces - Direct Vent, Ventless (Vent-Free), and B-Vent. Direct Vent fireplaces are the most popular option, while Ventless fireplaces give you flexibility with installation and don’t require a chimney. B-Vent is the least popular but has the most realistic flame appearance.

DIRECT VENT FIREPLACES

WHAT IS A DIRECT VENT GAS FIREPLACE?

Direct Vent fireplaces are efficient and safe alternatives to traditional gas and wood burning fireplaces. They don’t require a traditional brick chimney but instead, use a completely sealed venting system to pull fresh outside air into the firebox for combustion while simultaneously exhausting combustion gases outside of the home.



With a sealed venting system and firebox, Direct Vent fireplaces won’t draw air from inside the home for combustion, nor will combustion byproducts, like carbon monoxide, be able to enter back into the home.


This maintains indoor air quality and protects overall home efficiency while allowing the fireplace to work effectively.
