What type of chimney is designed for use with gas appliances?

C-vent or gas vent chimneys are specifically designed for venting gas appliances. These chimneys typically feature a double wall construction that allows for the safe expulsion of combustion gases while preventing heat loss and minimizing the risk of condensation. The design includes a flue that is constructed to handle the lower temperature exhaust produced by gas appliances, as well as to ensure proper draft and air intake.

Unlike other chimney types, which may be suited for different fuel sources such as wood or coal, B-vent chimneys are tailored for gas applications, making them a critical component in maintaining safety and efficiency in gas appliance operation. Their ability to operate at lower temperatures and their unique construction differentiated them from Class A, Metalbestos, and masonry chimneys, which serve other heating applications and have different structural requirements or material compositions.
