I Product Description
The AWI series boiler is a cast iron gas fired water boiler designed for use in closed forced circulation heating systems.
This boiler is a Category I draft diverter equipped appliance, 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 TWI series boiler is identical to corresponding sized AWI boiler except for the addition of baffles in the flue passages
to obtain higher AFUEs. The TWI is not available with a standing pilot or for use with propane gas.
