I Product Description
The Series 32 boilers are low pressure cast iron gas fired steam or hot water boilers designed for use in commercial heating
applications. 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. This boiler is intended for use with natural gas only.
The Series 32 may be used on low pressure steam heating systems or forced hot water heating systems and is intended for
installation in “closed” systems only. Hot water Series 32 boilers are available with up to two optional tankless heaters for
domestic hot water generation.
