I Product Description

The CWI series boilers are low pressure cast iron gas fired hot water boilers designed for use in closed hot water 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.

The CWI may be used on forced or gravity hot water heating systems. It is available with an optional tankless heater for domestic hot water generation.
