This includes having the boilers clean of soot and loose scale; fully warmed and at normal steam pressure; steam exhaust silencer system operable; all boiler, burner and fuel train pressure gages and thermometers calibrated; fuel meters in accurate operation (pressure/temperature correction factors provided, if applicable); boiler steam flow, stack temperature and flue gas oxygen instruments operating. E.VAMC will comply with any other requirements of the test personnel that are considered reasonable by VAMC and have been presented in writing at least two weeks prior to the scheduled testing. F.The inspections, testing and calibrations shall comply with: 1)The recommendations and requirements of VHA Boiler Plant Safety Devices Testing Manual, 3rd Edition. 2)The written recommendations of the equipment manufacturers. 3)The requirements and recommendations of NFPA 85 Boiler and Combustion Systems Hazards Code including applicable appendices. 4)Burner performance requirements in this document. G.A summary of the work is as follows: 1)Review boiler plant log sheets and alarm and trouble reports. 2)Review records that show combustion performance (flue gas oxygen and carbon monoxide). 3)Perform overall visual inspection of systems. Verify that systems comply with referenced codes and VAMC requirements stated in this contract. 4)Test and record the operation and set points of all burner/boiler safety interlock devices. Refer to list below. Verify that the set points and operating points are within approximately 20% of normal operating parameters. Make adjustments as necessary and record the new settings. The operation of a device must result in burner shutdown and/or proper alarm operation. 5)Operate burner(s) on each fuel from low fire to high fire and back to low fire in at least six increments and record combustion performance (flue gas oxygen, carbon monoxide, NOx where applicable), fuel train pressures, atomizing train pressures, burner pressures, stack temperatures, boiler steam output. 6)Compare the combustion performance data with VAMC requirements (see below) and previous readings. If necessary, make adjustments to the fuel flow and combustion air controllers, control valves and dampers to obtain the required performance. Record the new performance data. 7)Verify accuracy of instrumentation listed below. Verify that all devices are properly selected for the application in terms of type, size, set point range, performance, code approval. Calibrate all instruments that are not within manufacturer's specifications for accuracy. 8)Immediately inform COTR of any recommended repairs or modifications. H.All of interlocks and safety devices to be inspected and tested on each boiler/burner/equipment, are contained in the VHA Boiler Plant Safety Devices Testing Manual, 3rd Edition, along with testing procedures. I.Required burner performance (natural gas and fuel oil): 1)Turndown (ratio of maximum and minimum firing rates): 10/1 8/1 5/1 4/1 (Refer to original burner specification). 2)Achieve, but do not exceed, boiler maximum steam flow output rating. Measure fuel input at minimum and maximum firing rates. 3)Maximum carbon monoxide: 200 parts per million (ppm) 4)Maximum NOx: _____ (Refer to original burner specification). 5)Flue gas oxygen: 2.5 - 4.2% (Up to 5.2% at loads below 40% of maximum steam output; no upper limit at minimum firing rate; oxygen can be one percentage point higher on oil firing on single-point positioning systems). 6)Flue gas oxygen (low excess air burners): 1.0 - 2.0% (Up to 2.5% at loads below 40% of maximum steam output; no upper limit at minimum firing rate; oxygen can be one percentage point higher on oil firing on single point positioning systems). 7)No visible smoke, except on heavy oil fuel maximum opacity is 20%.

Report Requirements: A.Provide complete written report of the inspection fully describing all tests performed, all findings, and recommendations. The report shall have two sections the first section will be in a table form that with four columns: a.The first column labeled "FUNCTION" did the device pass or fail. b.The second column labeled "Device" list the device number and description in accordance with the VHA Boiler Plant Safety Devices Testing Manual, 3rd Edition. c.The third labeled "Deficiencies-Recommendations" d.The fourth column labeled "corrective actions" list any corrective actions taken during the inspection. The next section shall be in paragraph/bulleted form and list each device individual in accordance to the VHA Boiler Plant Safety Devices Testing Manual, 3rd Edition. Plus the section must reference the correct Master Specification and Standard Detail for that device. See sample below. 5.1. Condensate Storage Tank High Water Alarm Purpose: High water level may be an indication of condensate transfer pump failure that could lead to low water condition in the feedwater deaerator and in the boilers. There may be a failure of make-up water controls. Recommended set point: 4 inches below overflow level and 2/3 of tank height. Potential hazards due to failure of high water alarm: Feedwater deaerator running dry and, consequently, boiler feed pumps running dry will cause overheating and damage to pumps and potential for plant shut down. Failure of make-up water controls (in open position) could lead to significant cost from waste of water and condensate from the tank overflow if this occurs over a long time period. Recommended type of device: Conductivity probe type switch. Float type switches have high failure rate in this application where they are exposed to flash steam that causes seals to harden and prevent float movement. VA Master Specification section: 23 50 11 (old 15625). www.va.gov/facmgt/standard/ VA Standard Detail: SD232111-05.pdf www.va.gov/facmgt/standard/ Failure rate of float types: 48% (BEI study of VA boiler plants). Make and Model: Mercoid Float Did it function properly: No Category & Action Time Limit: Upon Failure or Within 5 Years Comments: Float type switches are not allowed for high water alarms. The VA recommended switch type is a conductivity probe type switch. Install the VA recommended switch and set to alarm at 2/3 of the tank height. There are valves that can isolate this alarm. These valves must be made lockable only in the operating position. B.Furnish report within one week of each facility inspection in "Microsoft Word" format by email to the COTR and to the VA Headquarters office designated. Provide hard copies of data sheets and flue gas analyzer "strip" printouts to the COTR within one week of visit. C.All safety-related deficiencies shall be immediately reported to the COTR, Boiler Plant Supervisor and/or Chief Engineer during the inspection visit. VHA CFM3A 1/4/10
