The Don Park BV8B5 is a high-quality Type B gas vent pipe section featuring an 8-inch nominal diameter and a 60-inch total length. Engineered specifically for venting low-temperature flue gases from Category 1 appliances, this pipe is widely used with residential and commercial gas furnaces, water heaters, boilers, and pool heaters. It is fully approved for systems operating on natural gas or liquid propane.
This double-wall vent pipe section is constructed with a fast-heating aluminum inner liner paired with a durable outer casing separated by an insulating annular air space. This thermal design minimizes heat loss through the pipe walls, maintaining a strong updraft and preventing corrosive flue condensation from forming within the system. It features a maximum continuous flue temperature rating of 243 degrees Celsius.
When assembling your venting layout, matching the correct diameters and locking mechanisms is vital to guarantee a gas-tight seal. This rigid section incorporates a simple twist-lock connection format for reliable, tool-free field assembly with compatible B-vent fittings. Always ensure a minimum one-inch clearance to combustible materials and verify local mechanical code compliance before concluding installation.
