This client requested a chimney lining as they were upgrading/converting their heating system and needed a chimney affidavit. We obtained the proper plans and permit for this installation.
The existing chimney required a stainless steel lining system to be custom fabricated and installed running on the interior of this approximately 55’ tall existing structure. The lining will be 18”x18” diameter 304 ASTM listed butt seam welded 10gage stainless steel pipe. The lining is resting on a steel plate that we installed at the base of the cleanout and we provided a gas tight cleanout as required by the DOB.
The chimney itself stands 16’ off the main roof. So we erected scaffolding to access the top of the structure for the duration of the project. At the top of the chimney 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.
