The 28A Series boilers are supplied completely knocked down for field assembly, knocked down but with an assembled block or as complete factory assembled packaged boilers. All boiler components should be inspected for damage upon receipt. Any damage should be immediately reported to the trucker or wholesaler. All boiler components should be stored in a clean dry area. To obtain the safe, dependable, efficient operation and long life for which this boiler was designed, these instructions must be read, understood and followed. The Series 28A boilers have been design certified by CSA. Each unit has been constructed and hydrostatically tested for a maximum working pressure of 15 psi for steam, 80 psi for water, in accordance with Section IV of the A.S.M.E. Boiler and Pressure Vessel Code for cast iron boilers. All aspects of the boiler installation must conform to the requirements of the authority having jurisdiction, or, in the absence of such requirements, to the National Fuel Gas Code, ANSI Z223.1/NFPA 54-latest revision or to the Installation of Oil Burning Equipment, ANSI/NFPA 31. Where required by the authority having jurisdiction, the installation must conform to the Standard for Controls and Safety Devices for Automatically Fired Boilers, ANSI/ASME CSD-1. In Canada, the installation must be in accordance with the requirements of CAN/CGA B149.1 or .2, Installation Code for Gas Burning Appliances and Equipment. In the Commonwealth of Massachusetts the installation of a gas burner must be performed by a licensed plumber or gas fitter. The owner should maintain a record of all service work performed with the date and a description of the work done. Include the name of the service organization for future reference.
