The building requested we reline the chimney for the boiler.
We installed 126’ of 16” 304 ASTM listed butt seam welded 10gage stainless steel pipe.
We installed a steel base plate for the lining.
We fabricated and installed a gas tight clean out for the base of the chimney as required by the NYC DOB
We connected the newly installed lining to the existing breeching using a stainless steel tee fitting.
At the top of the chimney the existing extension needed to be removed for install. Upon completion we installed a custom fabricated chase with cutout and 6” wrap to secure lining in place..
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.
