The CGS-C series boilers are low pressure cast iron gas fired steam boilers designed for use in closed steam heating
systems. These boilers are Category I draft diverter equipped appliances, which must be vented by natural draft using a lined
masonry or listed metal chimney system. An adequate supply of air for combustion, ventilation and dilution of flue gases
must be available in the boiler room. These boilers are not designed for use in process or other “open” steam systems
