Type B vent is a manufactured round vent used on which type of appliances?

Type B vent is specifically designed for use with gas-burning appliances. This venting system is engineered to handle the high temperatures and the corrosive byproducts of combustion produced by gas appliances, such as furnaces, water heaters, and other natural gas or propane units.

The design of Type B vent allows for proper exhaust of flue gases while preventing backdraft and ensuring safety from any potential carbon monoxide hazards. It features a double-wall construction that provides insulation and maintains the necessary temperature to promote proper draft and venting efficiency.

In contrast, electric appliances do not produce combustion gases that require venting, while wood-burning and oil-burning appliances have their own specific venting requirements that differ from those of gas appliances. Each type of fuel generates different byproducts and operates at varying temperatures, necessitating distinct venting materials and designs to ensure optimal safety and functionality. Thus, Type B vent is exclusively suited for gas-burning appliances.
