Dickinson Marine Barometric Damper
A short piece of pipe with a 1” crimp for connecting on one side, 304 stainless steel, with barometric damper, used after the first piece of pipe from the top of your heater or stove. The barometric damper helps decrease the draft on longer chimneys allowing the user to operate the unit on lower fuel settings. Recommended on all installs.
