CI-HGS 3-pass Water series

By recirculating combustion gases within the unique 3-pass cast iron heat exchanger, the New Yorker CI-HGS is designed to extract every BTU possible from the combustion process. The cast iron sections are produced by Burnham Foundry, LLC in Zanesville, Ohio and are the primary reason why the CI-HGS is able to attain an ENERGY STAR certified 86% AFUE.


The cast iron sections in the CI-HGS are joined with steel nipples.These connectors resist petroleum-based chemicals such as anti-freeze which can deteriorate rubber seals used by some competitors. What this means to you is increased longevity of your boiler’s life.


New Yorker uses only name-brand controls and components, assuring that the CI-HGS will provide years of comfortable, reliable heating. The heat exchanger construction also meets the requirements of the ASME Boiler and Pressure Vessel Code which ensures the quality and safety of the boiler.
