Expert Verdict — Reviewed by the SuperArbor Pro Desk
Match the top diameter to your vent pipe diameter and confirm the appliance is listed for Type B venting before specifying. Keep the assembly vertical and follow DuraVent's clearance-to-combustibles and termination height requirements during layout. Pipe tops install after the pipe run and flashing are set, so stage the termination last.
Do not use Type B gas vent with wood- or coal-burning appliances, grease ducting or high-temperature exhaust, and follow local codes and clearance requirements for roof terminations.
