Expert Verdict — Reviewed by the SuperArbor Pro Desk
Always verify the appliance is listed for Type B venting before specifying this cap, and size the vent per the appliance manufacturer's tables. Match the cap diameter to the pipe size, not the appliance collar. Inspect the cap periodically for blockages from debris or nesting birds.
Type B venting must be installed according to the appliance listing and applicable codes; have a qualified installer confirm sizing and clearances.
