This gas-fired design combines the durability and economy of cast iron with high quality components to ensure years of efficient, reliable heating. The rugged cast iron heat exchanger and boiler structure maximize heat transfer, for the most efficient use of fuel. Metal section connectors resist petroleum based chemicals.

The CGS-A Series is completely factory assembled and wired. With annual efficiencies of up to 81.5%, the CGS-A boiler is a solid investment that can pay for itself when used to replace an inefficient, existing boiler. And, of course, New Yorker stands behind the Classic CGS-A Series with our 10 Year Limited Warranty.
