This client needed to get their chimney up to code for a boiler upgrade/conversion so requested an inspection. The chimney was clay and had cracks throughout.
We recommended relining the chimney using 10gage stainless steel. We had to remove the existing clay tiles in the chimney to fit the proper sized 10gage lining.
We obtained the plans and permit for the chimney installation.
For the project we erected scaffold on the roof for access to the top of the chimney for the duration of the project. We installed over 100’ of round ASTM listed butt seam welded 10gage stainless steel pipe.
We installed a base plate on which to land the chimney. At the base of the chimney we installed a gas tight clean out as required by the NYC DOB.
We connected this newly installed chimney lining to the existing breeching using a custom fabricated tee fitting.
At the top of the chimney we installed a custom fabricated chase cover with a cut out and 6” wrap to secure the chimney lining in place.
Once the lining was installed we performed a pressurized smoke test and issued the chimney affidavit for NYC DOB and Con-Edison.
