Product Details

Description

This premium 4-inch by 24-inch B-Vent pipe is a critical component for safely venting exhaust gases from residential and commercial gas-fired appliances. Designed with a durable double-wall construction, it features an inner aluminum liner that heats up quickly to promote a strong draft and minimize condensation, while the galvanized steel outer pipe provides structural integrity and maintains the necessary clearance to combustibles. Ideal for use with gas water heaters, furnaces, and boilers, this 2-foot venting section ensures efficient performance and long-lasting reliability. The standardized design allows for easy, secure installation with a professional-grade twist-lock mechanism, making it a dependable choice for HVAC repairs, system upgrades, and new venting installations.
