DVL double-wall stove pipe completes the venting system when used with one of DuraVent’s chimney products, such as DuraTech or DuraPlus. DVL’s double-wall, air-insulated design reduces clearances to combustibles from 18” to 6”, the closest clearance to a wall of any connector pipe. DVL improves stove performance by maintaining high flue gas temperatures for a strong, steady draft. Because the inner wall is stainless steel the flue heats up faster, stays hotlonger, minimizes the formation of creosote, and has the same life expectancy as the chimney. Adjustable lengths eliminate the need for cutting or crimping.Required for Manufactured Home installations. See appliance manufacturer's installation instructions.

Is this the adapter used for going thru a wall using the wall thimble 9043ss. and is the connection made right at the wall thimble or before allowing the chimney pipe to come thru to the inside?

The Simpson Dura-Vent 8674 is an adapter used to connect single wall stove pipe to double or triple wall chimney pipe. The wall thimble you've mentioned is a passthrough and pipe does not directly connect to it.


Yes, this is the correct item to complete the transition.

Can this be used to connect double wall stove pipe to the flexible chimney liner? Both 6" inside diameter.

This allows you to go from single wall stove pipe to double wall, mainly used as a transitional piece to go to Class A pipe. Let me know if you have any other questions (800) 864-2555 x447.
