Direct-vent appliances are typically higher in efficiency than b-vent appliances and put out a lot of heat even with a low flame setting but still do not produce as much heat as their vent free counterparts.
When should b-vent be used?
Type B vents are vents suitable only for listed, draft-hood equipped, gas-fired appliances, including most domestic heating and hot water systems. any appliance that produces flue gasses that exceed 480° F (249° C).
Is vent free or direct vent better?

For vent-free gas inserts to reduce the risk of emissions being transmitted into the home, the burn temperature of the fire needs to be higher. So, this higher temperature produces a less realistic, sometimes blue flame.
Are direct vent fireplaces worth it?
