New Yorker CG30-FNGH Cast Iron Hot Water Boiler, Natural Gas, 62,000 BTU

The New Yorker CG30-FNGH is a gas-fired, non-condensing cast iron boiler for hot water heating. It has 62,000 BTU input and a 45,000 BTU net IBR rating, the smallest output among the CG models here; match it to the home's heat loss and radiation.

The cast iron heat exchanger uses metal section connectors for long service and even heat transfer in hydronic systems. Ignition is intermittent electronic with a step-opening gas valve for smooth starts, and the boiler pairs an integrated control with thermal purge with a factory vent damper.

As a Category I natural-draft unit with a draft hood, it connects through a 4 in. flue to a lined masonry chimney or an approved metal chimney, a practical fit where an existing chimney is reused. Supply and return tappings are 1-1/4 in. NPT, the gas inlet is 1/2 in. NPT, and power is 120 V, 60 Hz, single phase.
