Type B-W gas vents are required for which type of furnaces?

Type B-W gas vents are specifically designed for use with vented wall furnaces. These vents accommodate the combustion gases produced by appliances that are installed in walls and require a means to safely exhaust those gases outside. Vented wall furnaces run on natural gas or propane and are designed to provide efficient heating in areas where traditional ducted systems may not be feasible.

The construction of Type B-W vents allows for the handling of higher flue gas temperatures produced by these wall-mounted appliances, ensuring safe and efficient venting. They are made from materials that can endure the conditions within the venting system while providing protection against backdrafting and enhancing overall system safety.

Understanding the specific applications for different types of gas vents is crucial for ensuring proper installation and adherence to safety codes in mechanical systems. Other types of furnaces, such as central heating, portable, or floor furnaces, require different venting solutions suitable for their designs and operational parameters, which is why they do not utilize Type B-W gas vents.
