In Test No. P-1 retain boiler at each load point for a time period sufficient to permit stabilization of flue gas temperature and other parameters. Steam loads for tests may be furnished by the hospital systems, by operation of the steam silencer vent system, or by a combination of the above. Utilize dry bulb and wet bulb thermometers furnished and retained by Contractor for checking combustion air. Smoke testing shall be by visual observation. If smoke density monitor is not provided, utilize Bacharach Model 21-7006 Smoke Test Kit. If there is disagreement with the results of these tests, provide qualified observation person and tests in compliance with EPA Reference Method 9 (CFR 40, Part 60, Appendix A). An additional efficiency test will be required, conforming to ASME Performance Test Code PTC 4, if the boiler efficiency determined in the Test P-1 above, does not comply with requirements. Utilize ASME Test Forms PTC 4.1.a, 4.1.b, and the abbreviated input-output and heat balance methods. Compare the combustion performance data with VAHCS requirements and previous readings. (Flue gas oxygen, carbon monoxide and NOx). If necessary, make adjustments to the fuel, combustion air controllers, and FGR controller and damper to obtain the required performance. Record the new performance data. Flash S.D. card with new tune.
