Crown Kingston
Oil-fired steam boiler for homes with chimneys
The Kingston boiler provides hot water heat in a variety of sizes (78,000 to 235,000 heating capacity BTU/HR) to serve a wide range of homes. An approved chimney is required.
The boiler design is proven in service to be reliable. It is easy to maintain and economical in its purchase price and fuel consumption. The boiler can be ordered with flame retention Beckett, Carlin or Riello oil burners.
The boiler features a swing-open burner door that gives full access to the combustion chamber and burner nozzle. A split jacket provides easy access to the flue passages of the heat exchanger. The attractive and durable jacket is powder-coated to resist scratching and insulated to retain heat. The heat exchangers are constructed to meet the standards set by the American Society of Mechanical Engineers.
The Kingston has a wet base design in which the heat exchanger surrounds the combustion chamber on all sides to provide optimum heat transfer. The result is lower fuel costs.
 On the Kingston steam boiler, the heat exchanger is assembled with steel push nipples below the water line where resistance to expansion and contraction is important, and cast iron push nipples above the water line where corrosion resistance is key. The cast iron push nipples are larger than usually found on such units to provide optimum steam quality.
Kingston…the latest in a series of designs that is constructed for long life, convenient to install and service, and designed to provide the most value for each energy dollar. That's CROWN's commitment to quality.
