Product Details

Provides connection between DuraTech chimney systems and the Combustion Air Stovepipe. Adjusts to fit wall thicknesses from 5 1/2" to 10". Extends into room 6".

Outside air is drawn through the wall thimble's baffles, helping it pre-heat as it comes in contact with the hot inner exhaust pipe. The air continues down an inner chamber of the combustion air stove pipe, through the aluminum flex and into the appliance, delivering fresh combustion air.
