Venting Products

B-vents, also called Type B vents, direct gases produced by furnaces, gas fireplaces and water heaters out of a building, preventing harmful carbon monoxide from building up inside. The vent has one inner pipe that carries the hot air out and an outer pipe that draws clean air in, facilitating combustion and preventing internal condensation.

These vents protect occupants and their living spaces from health hazards, and due to their versatility and compatibility with different gas appliances, they are suitable for both residential and commercial applications.
