At 4 inches in diameter and 60 inches in length, this pipe section covers longer straight runs while maintaining flue gas temperature through its double-wall construction. The outer wall keeps clearance-to-combustibles requirements manageable, and the inner wall retains heat to sustain proper draft. Licensed gas fitters and HVAC technicians install this pipe when venting Category I gas appliances such as furnaces, boilers, and water heaters through interior chase or attic runs.\u003c\/p\u003e\u003cp\u003eThis pipe section is suited for residential and light-commercial installations where Category I gas appliances require a listed Type B vent system. Its 60-inch length reduces the number of joints needed on straight vertical or horizontal vent runs, which simplifies installation and limits potential leak points. Twist-lock connections secure each section to fittings, elbows, and other DVP system components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDouble-wall construction maintains flue gas temperature and supports proper draft\u003c\/li\u003e\n\u003cli\u003e4-inch diameter x 60-inch length covers extended straight vent runs with fewer joints\u003c\/li\u003e\n\u003cli\u003eTwist-lock connection system for secure, tool-free assembly with compatible DVP components\u003c\/li\u003e\n\u003cli\u003eRound rigid design for straightforward routing through interior chases and attic spaces\u003c\/li\u003e\n\u003cli\u003eListed for Category I gas appliance venting applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard component for Type B double-wall vent systems venting Category I gas appliances.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation must be performed by a licensed gas fitter or HVAC technician in accordance with the International Fuel Gas Code (IFGC) and the appliance manufacturer's venting instructions. Shut off the gas supply and allow the appliance to cool completely before servicing or extending any vent system. Maintain all required clearances to combustibles as specified by the vent system listing.
