New Yorker CGS60-CNIH Cast Iron Steam Boiler, 175,000 BTU, Natural Gas

The New Yorker CGS60-CNIH is a chimney-vented, cast-iron gas steam boiler in the 175,000 BTU class for larger homes with one-pipe or two-pipe radiator systems. It burns natural gas at up to 82.1% AFUE and keeps a low jacket height for tight basements.

Input is 172,000 BTU/h, DOE heating capacity is 142,000 BTU/h and the Net IBR steam rating is 107,000 BTU/h, about 445 sq. ft. EDR. Stainless steel burners and metal section connectors join the cast-iron heat exchanger, while intermittent electronic ignition and a factory vent damper reduce standby losses. It carries an ASME H stamp along with AHRI and ETL listings.

Because the draft diverter is part of the jacket, no tall external draft hood is needed. It vents through a 6 in. flue into a lined masonry or approved metal chimney. Supply and return tappings are 2 in. NPT, sized for a full header and equalizer that help produce dry steam, and the gas inlet is 3/4 in. NPT. Water content is 9.3 gal, and an LP conversion kit is available.
