We installed 200’ of 22” diameter 304 ASTM listed butt seam welded 10gage stainless steel pipe.
We installed a base plate for the lining to land on.
We installed a gas tight clean out at the base of the chimney as required by NYC DOB.
We connected the newly installed chimney lining to the existing breeching using a stainless steel tee fitting.
We erected scaffold to access the top of the chimney for the duration of the project.
We installed a custom fabricated chase with cutout and 6” wrap to secure lining in place. The pipe terminated 3’ above the top of the chimney.
Once the lining was installed we performed a pressurized smoke test and were able to issue the chimney affidavit for NYC DOB and Con-Edison.
