This is a Dura Tech chimney by Duravent installed in a job from a fire restoration job that our installation affiliates at "Accurate Installation" installed. This project used mostly galvanized option chimney pipe as it is enclosed in a wooden chase box. Installing a flue through a wall was a key part of this project, particularly evident in how the pipe was managed. This job was not fully completed at the time of the photos as a longer length was needed through an adjustable wall thimble and the section going through the wall in the picture was added as a drip leg under the tee.
