2Boiler Division Established in 1881, 133 years old Regulate the Construction, Installation, and Inspection of Boilers and Pressure VesselsBoats for hireHistorical BoilersManufacturers and Repair Firms
3Boiler Division 10- Inspectors 78,736- Boilers and Pressure Vessels Approximately 20,000 boilers242- Historical Boilers103- Boats78- ASME / National Board Stampholders
4Boilers Steam boilers over 100,000 btu input HWH boilers over 750,000 btu inputHWS boilers over 500,000 btu inputBuilt to ASME CodeRegistered with the National BoardCompliance with ASME CSD-1 requiredAll new installations of steam and HWH boilers must be hydrostatically tested after installation is complete and before boiler is put in operation. Test must be witnessed by a State inspector. Hydrostatic test requirements do not apply to HWS.
5Pressure Vessels Inspection Required Air storage greater than 5 cubic feet (38 gallons) or 100 psiAir storage greater than 1.5 cubic feet (11.22 gallons) and 600 psiOther tanks over that exceed 210 degrees, 160 psi, or 120 gallonsPossible changes to Section VIII, for pressure vessels

8CF-190 Vents, Bleeds, and Relief valve lines Vent Lines: piping or tubing that conveys the release of gases from fuel train componentsBleed Lines: piping or tubing that conveys the release of gases from fuel train components, which periodically releases gas pressure to the atmosphere in order to operate properlyRelief Valve Lines: piping or tubing that conveys the release of gas from the relief valve
9CF-190 Vent LinesGas-pressure regulators, combination gas controls, pressure interlock switches, and all other fuel train components requiring atmospheric pressure to balance a diaphragm shall have the atmospheric side of the diaphragm connected to a vent line that shall be piped by the installer to the outdoors at a safe point of discharge as determined by the AHJ.
10CF-190 Bleed LinesGas-pressure regulators, combination gas controls, pressure interlock switches, and all other fuel train components that periodically release gas into the atmosphere in order to properly operate shall be connected to a bleed line that shall be piped by the installer to the outdoors at a safe point of discharge as determined by the AHJ.
11CF-190 Vent LimitersGas pressure regulators, combination gas control, pressure interlock switch, or other fuel train components incorporating a vent limiter shall be permitted to vent directly into ambient space.
12CF-190 Gas Pressure Relief Lines Outlets of gas pressure relief valves shall be piped by the installer to the outdoors at a safe point of discharge as determined by the AHJ.Piping must be the same size or greater than the outlet connection to the valveMultiple relief lines must be piped independently
13CF-190 Vent Valve linesVent Valve: A normally open, power closed valve piped between the two safety shutoff valves.Must be piped outdoors by installerPiping must be full size for the entire lengthMultiple lines must be piped seperately
14CF-190 Manifolding Lines Must be approved by AHJ Shall have cross sectional area of the largest branch line plus 50% of the additional cross sectional area of additional lines
15CF-190 Manifolding lines The following is not permitted Manifolding gas-pressure relief linesManifolding of vent valve lines with vent lines or bleed linesManifolding of any vent, bleed, relief, or vent valve lines of one boiler unit to any lines from another boiler
16CF-190 Vents, Bleeds, etc.Combination gas control integrating an internal gas bleed line shall be permitted to discharge its bleed line back into the valve bodyPiping or line point of discharge shall be protected from foreign material, moisture, or insectsBleed or vent lines may discharge to a continuous pilot, not manifolded and point of discharge uses a burner tip
17Code Facts, Section IV ASME Certification Mark “H” Designator for shop/field assembled boilersUse of Stainless Steel (HF-201)Limited to 210 degrees Maximum TemperatureSafety valve mounting
18Section IV BoilersHamilton Engineering (EVO Boilers)
20Section IV Boilers (Viessmann) Must Comply with ANSI Z21.13 or CSD-1Observation port for burner and main flameVitodens 200-W
21Section IV Boilers (Viessmann) ANSI Z 188.8.131.52Provision shall be made to permit observation of main burner flames during adjustment and under operating conditions.1.6.15A flame observation port of a direct vent boiler shall be constructed of heat resistant material and, unlesslocated within the cabinet casing, shall be protected from mechanical damage. Glass, if used, shall beframed and not less than 1/8 in (3.2 mm) thick.
22Section IV Boilers (Fulton Pulse) Gems Sensors, Probe type LWCODoes not prove lockout, resets after 60 second test.Under Review by CSD-1 Committee
23Section IV Boilers (Aerco) Combustion Air Proving SwitchMust be tested by AERCO trained TechnicianTest performed at start upHigh Temp Limit SwitchNew sensors eliminate over temperature prior to shutting off fuel supply to burner

30Important Dates 1957: ASME Code 1982: NBIC 1984: CSD-1, 1982 Edition Steam: 2 LWCOSteam: High Pressure Limit, Manual ResetHWH: LWCO with Manual ResetHWH: High Temp limit with Manual Reset1993: E-Stop1994: National Board RegistrationCurrent Edition Adopted: 2012
31Inspection Reports Electronic Transfer, 75% Violation Tracking Must be written outEach Report must have one of theseMNB (State Reg No / Jurisdiction No)NB (National Board Number)Serial No, or Other No
32CSD-1, CW-520Water heaterA vessel which is closed except for openings through which water can flow, that includes the apparatus by which heat is generated and on which all controls and safety devices necessary to prevent pressure greater than 160 psig and water temperatures greater than 210 degrees F are provided, in which potable water is heated by the combustion of fuels, electricity or any other heat source withdrawn for external use.
33CSD-1, CW-520 Hot water supply boiler ASME Code Section IV A boiler that furnishes hot water to be used externally to itself at a pressure less than or equal to 160 psig or a temperature less than or equal to 250 degrees F at or neat the boiler outlet.ASME Code Section IVLimits Temperature of Water Heaters to 210 degrees F, and 160 psi (HLW stamp)
35NB Bulletin, Winter 2014Which capacity should be used? The answer: match the code of construction with the certified capacity rating. If the valve is protecting an ASME Section IV code-stamped hot water heater, then use the ASME/National Board capacity which is determined by ASME Section IV requirements. If it is not ASME Section IV code stamped, then use the CSA rating.
