New Yorker CG50-FNGH Cast Iron Hot Water Boiler, 130,000 BTU, Natural Gas

The New Yorker CG50-FNGH is a gas-fired, non-condensing cast iron boiler for hot water heating. It has 130,000 BTU input, 108,000 BTU heating capacity and a 94,000 BTU net IBR rating; final selection should follow 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 a vent damper is included.

As a Category I natural-draft unit with a draft hood, it connects through a 6 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.
