All valves shall meet requirements of Section 220523. Thermometers and gauges shall meet requirements of Section 220519. BOILER DESIGN NOTE: The plans shown are based on Superior/Easco/Johnston Boilers and are intended to be schematic and may not be correct in all details (such as the location of all outlets and inlets) to the unit by the University or being provided by this contractor. The Contractor shall review the shop drawing available from the University or his vendor and allow sufficient funds in his base bid for any additional work required to suit the unit being supplied. All equipment shipped loose shall be installed and piped as directed by the manufacturer and/or owner, by this contractor. EXECUTION FACTORY TESTING Each complete boiler/burner unit must be fire tested at the manufacturer’s plant prior to shipment. Owner has the option to witness the test. Provide at least six weeks' notice. Provide test report for field setup. The unit shall operate at minimum of 84.75% overall efficiency, based on higher heating value for natural gas. The following procedure shall be employed for determining the boiler's efficiency. If the indicated efficiency is not achievable, indicate with the bids, achievable efficiency. Operation of the boiler shall be to establish efficient and stable fuel air ratio over the complete load range. Operation of the unit shall then be continued for testing and demonstration of the certified efficiency at rated capacity. This test is to take place on the factory fire test stand. The efficiency test shall consist of the accurate measurements and recording of the following listed factors: O2 and combustibles in gases Ambient air temperature Feed water temperature Stack temperature Steam pressure Feed water flow On completion of the test, the following listed heat losses shall be calculated as prescribed under "Heat Loss Efficiency" of the ASME TEST FORM ABBREVIATED EFFICIENCY per Power Test Codes PTC41: Heat loss due to dry gas Heat loss due to moisture in fuel Heat loss due to moisture from combustion of hydrogen
