Which gas appliances can be vented using B vent according to the data?

• A. All gas appliances
• B. Only furnaces
• C. Only water heaters
• D. No gas appliances

Answer: (A)

B-vent is a double-wall venting system designed to carry combustion gases from gas-fired appliances that rely on natural draft to the outdoors. Because these appliances vent through a vertical chimney or vent that allows the hot gases to rise, many types of equipment—such as furnaces, water heaters, and boilers—are listed for use with B-vent. When the data states that B-vent can be used for all gas appliances, it’s reflecting that, within typical listing and code guidance, this venting method covers a wide range of gas-fired equipment as long as the appliance is approved for B-vent and the installation follows the manufacturer’s instructions, vent size, height, and clearance requirements. It’s important to note that not every gas appliance uses B-vent. Sealed-combustion units and direct-vent appliances often require concentric or PVC venting and may not be suitable for B-vent. Always verify the appliance listing and applicable codes for the specific installation.
