The BSI 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.
