Will my DLV double wall stove pipe with a 6" id and a 7" OD pass through this thimble ?
By Tyler M. - NFI Certified Specialist on July 9, 2013
Your DVL double-wall stovepipe is not meant to pass through this thimble; it should be converted to the 6" inner-diameter DuraTech pipe right as it gets to the wall. For this connection, you would need the DuraTech 6" Finishing Collar
. Then, you would use a 6" DuraTech pipe length through the thimble into the 6" DuraTech tee
with accompanying tee support bracket
. From there, you would run the DuraTech pipe vertically up over the roof line.

I have a 8" triple wall Dura vent chimney in place through my overhang. My fireplace has a 6" opening. I want to go up inside and 90 degree through the wall with a 6" pipe and connect to the 8" triple wall. I'm not sure what product I need to connect the two?
By Will M. on December 12, 2016
Answer:We will need confirmation of the brand to ensure we are making the correct recommendations. If this is DuraPlus, there should be no issue when connecting a wood stove. However, we will also need to know the make and model number of the wood stove as this was referred to as a "fireplace" and you may not use 90 degree elbows with an open-combustion wood burning fireplace.

I am installing a small wood stove in my garage. The wall is 4" thick. What is the correct 6" wall thimble?
By Tyler M. - NFI Certified Specialist on February 11, 2014
This wall thimble can be used for your application (the body of the thimble can be trimmed to account for the narrow wall), provided your are using 6" inside diameter chimney. If you need a full quote for your chimney installation, please fill out our

How large of a hole do I need through my poured concrete wall to run this wall thimble?

Answer:The sleeve that passes through the wall is 8.25" in diameter. This is just large enough to have the pipe slip through.

Do I need to install a wall thimble if the tee is passing through a poured concrete wall?
By Will M. on April 17, 2017
Answer:You do not need to use a wall thimble if a class A chimney section is passing through this concrete wall. The chimney section would extend indoors from the tee snout connection outdoors and a finishing collar would be used to transition from class A chimney to double or single wall stovepipe for the interior run towards the stove.
