" intensive study and effort to make the highest D9IutR-#ncA-eef-/or Heating grade equipment for heating buildings. They are adapted to the burning of any grade of fuel and will maintain high efficiency when operating to supply the variable demands of a heating load. Kewanee Smokeless BOILER -Portable-far Heating The rated capacity is the amount of direct radiation that the boiler will carry with a firing interval of three to four hours depending upon the grade of fuel used. No discount in rating is ad vised as reserve capacity has been allowed to care for the most severe weather conditions. Kewanee Boilers are built of steel (riveted) using as a minimum basis the rules of construction adopted by the American Society of Mechanical Engineers, known as the A. S. M. E. Boiler Code. Ratings The rated capacity of Kewanee Boilers, as shown, is the number of square feet of direct radiation or equivalent which the boiler will carry, if sufficient radiation is installed to heat the building to 70 degrees fahrenheit. The ratings are based on a standard for steam of 2 lb. pressure at the boiler, and for water on a mean temperature of 180 deg. fahr. as the water leaves the boiler. 337
