Olymberyl Aidan Top Flue Outlet Section

The top flue outlet section is the cast iron component that forms the upper flue exit on the Olymberyl Aidan when used in top-exit configuration. It channels combustion gases from the firebox into the flue collar and liner above. This part takes sustained heat stress and can crack after extended use. Replace it if the section shows visible cracking or significant corrosion.

A cracked flue outlet section is a direct route for combustion gases to escape into the room. It should be inspected as part of any annual service and replaced immediately if cracking is found. The section is designed to last many years under normal use, but overfire events can shorten its lifespan significantly.
