The cast iron heat exchanger delivers durable, long-term performance, while the integrated Honeywell gas valve and electronic ignition system provide reliable, repeatable startup. A probe-type low water cutoff (LWCO), 15 psi pressure relief valve, steam pressure gauge, and built-in draft diverter come factory-installed, reducing field assembly time for licensed heating technicians.\u003c\/p\u003e\n\u003cp\u003eThe cgs50cni-h is suited for retrofit and new-install applications in residential and small commercial buildings with existing one-pipe or two-pipe steam distribution systems. With a DOE heating capacity of 113 MBH and a Net IBR rating of 85 MBH, it covers up to 354 square feet of steam radiation. The unit is designed for horizontal venting through a 6-inch flue collar and mounts directly to a level floor. Supply and return connections are 2-inch threaded, and the gas connection is 1\/2-inch threaded, matching standard residential steam piping configurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCast iron heat exchanger with aluminized and stainless steel burners for long service life\u003c\/li\u003e\n  \u003cli\u003e82% AFUE with 138 MBH AGA input rating and 113 MBH DOE heating capacity\u003c\/li\u003e\n  \u003cli\u003eFactory-installed probe-type LWCO, steam pressure gauge, and 15 psi safety relief valve\u003c\/li\u003e\n  \u003cli\u003eBuilt-in draft diverter and vent damper support horizontal venting through a 6-inch flue collar\u003c\/li\u003e\n  \u003cli\u003eElectronic intermittent ignition system eliminates standing pilot\u003c\/li\u003e\n  \u003cli\u003eInsulated jacket, flame rollout switch, blocked vent switch, and drain valve included from the factory\u003c\/li\u003e\n  \u003cli\u003eMetal section connectors resist chemical degradation and extend boiler section life\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style floor-mount cast iron steam boiler replacement for natural gas steam heating systems requiring 2-inch threaded supply and return connections and horizontal venting with a 6-inch flue collar.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed heating contractor or plumber in accordance with applicable local codes, NFPA 54, and the manufacturer installation manual.
