Boiler Division Established in 1881, 133 years old Regulate the Construction, Installation, and Inspection of Boilers and Pressure Vessels Boats for hire Historical Boilers Manufacturers and Repair Firms

Boiler Division 10- Inspectors 78,736- Boilers and Pressure Vessels Approximately 20,000 boilers 242- Historical Boilers 103- Boats 78- ASME / National Board Stampholders

Boilers Steam boilers over 100,000 btu input HWH boilers over 750,000 btu input HWS boilers over 500,000 btu input Built to ASME Code Registered with the National Board Compliance with ASME CSD-1 required All 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.

Pressure Vessels Inspection Required Air storage greater than 5 cubic feet (38 gallons) or 100 psi Air storage greater than 1.5 cubic feet (11.22 gallons) and 600 psi Other tanks over that exceed 210 degrees, 160 psi, or 120 gallons Possible changes to Section VIII, for pressure vessels

CF-190 Vents, Bleeds, and Relief valve lines Vent Lines: piping or tubing that conveys the release of gases from fuel train components Bleed 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 properly Relief Valve Lines: piping or tubing that conveys the release of gas from the relief valve

CF-190 Vent Lines Gas-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.

CF-190 Bleed Lines Gas-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.

CF-190 Vent Limiters Gas 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.

CF-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 valve Multiple relief lines must be piped independently

CF-190 Vent Valve lines Vent Valve: A normally open, power closed valve piped between the two safety shutoff valves. Must be piped outdoors by installer Piping must be full size for the entire length Multiple lines must be piped seperately

CF-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

CF-190 Manifolding lines The following is not permitted Manifolding gas-pressure relief lines Manifolding of vent valve lines with vent lines or bleed lines Manifolding of any vent, bleed, relief, or vent valve lines of one boiler unit to any lines from another boiler

CF-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 body Piping or line point of discharge shall be protected from foreign material, moisture, or insects Bleed or vent lines may discharge to a continuous pilot, not manifolded and point of discharge uses a burner tip

Section IV Boilers (Viessmann) ANSI Z 21.13 1.6.14 Provision shall be made to permit observation of main burner flames during adjustment and under operating conditions. 1.6.15 A flame observation port of a direct vent boiler shall be constructed of heat resistant material and, unless located within the cabinet casing, shall be protected from mechanical damage. Glass, if used, shall be framed and not less than 1/8 in (3.2 mm) thick.

Inspection Reports Electronic Transfer, 75% Violation Tracking Must be written out Each Report must have one of these MNB (State Reg No / Jurisdiction No) NB (National Board Number) Serial No, or Other No

CSD-1, CW-520 Water heater A 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.

CSD-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 IV Limits Temperature of Water Heaters to 210 degrees F, and 160 psi (HLW stamp)

CSA vs AMSE/NB Capacity http://www.nationalboard.org/SiteDocuments/Bulletins/WI2014.pdf

NB Bulletin, Winter 2014 Which 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.
