This double-wall Type B gas vent pipe features a 10-inch internal diameter and a 36-inch length, providing an optimal run section for vertical heating exhausts. Constructed with an inner pipe made of reflecting aluminum, it heats up rapidly to contain warm flue gases and minimize condensation, while the integrated internal airspace offers permanent insulation.
The outer pipe is built from corrosion-resistant galvanized steel, ensuring excellent structural strength, safety, and protection against handling damage during assembly. This insulated arrangement maintains a 1-inch minimum clearance to combustible materials across single and multi-family structures, making it well-suited for venting Category 1 natural gas or propane furnaces, boilers, and water heaters.
With a maximum temperature rating of 243 degrees Celsius, this rigid gas vent segment delivers efficient draft performance while keeping surrounding enclosure surfaces cool. Professional HVAC technicians specify this 3-foot section for its robust connection design, allowing easy, secure joint attachment without requiring specialized engineering or extensive on-site modifications.
