3 = Article in part.
307 = Paragraph within Article 3.
(c) When a paragraph or a section of the regulations in this part relates to material in section IV of the ASME Boiler and Pressure Vessel Code, the relationship with the code will be shown immediately following the heading of the section or at the beginning of the paragraph, as follows:
(1) (Modifies H______.) This indicates that the material in H______ is generally applicable but is being altered, amplified or augmented.
(2) (Replaces H______.) This indicates that H______ does not apply.
(3) (Reproduces H______.) This indicates that H______ is being identically reproduced for convenience, not for emphasis.
§ 53.01-5 - Scope (modifies HG-100).
(a) The regulations in this part apply to steam heating boilers, hot water boilers (which include hot water heating boilers and hot water supply boilers), and to appurtenances thereto. The requirements in this part shall be used in conjunction with section IV of the ASME Boiler and Pressure Vessel Code (incorporated by reference; see 46 CFR 53.01-1). table 54.01-5(a) of this subchapter gives a breakdown by parts in this subchapter of the regulations governing various types of pressure vessels and boilers.
(b) Modifies HG-100. The requirements of part HG of section IV of the ASME Boiler and Pressure Vessel Code shall be used except as noted otherwise in this part.
§ 53.01-10 - Service restrictions and exceptions (replaces HG-101).
(a) General. The service restrictions and exceptions shall be as indicated in this section in lieu of the requirements in HG-101 of section IV of the ASME Boiler and Pressure Vessel Code (incorporated by reference; see 46 CFR 53.01-1).
(b) Service restrictions. (1) Boilers of wrought materials shall be restricted to a maximum of 103 kPa gage (15 psig) for steam and a maximum of 689 kPa (100 psig) or 121 °C (250 °F) for hot water. If operating conditions exceed these limits, design and fabrications shall be in accordance with part 52 of this subchapter.
(2) Boilers of cast iron materials shall be restricted to a maximum of 103 kPa gage (15 psig) for steam and to a maximum of 206 kPa gage (30 psig) or 121 °C (250 °F) for hot water.
(c) Hot water supply boilers. (1) Electrically fired hot water supply boilers that have a capacity not greater than 454 liters (120 gallons), a heat input not greater than 58.6 kilowatts (200,000 BTU per hour), and are listed as approved under Underwriters' Laboratories UL 174 or UL 1453 (both incorporated by reference; see 46 CFR 53.01-1) are exempted from the requirements of this part provided they are protected by a pressure relief device. This relief device need not comply with § 53.05-2.
(2) Oil fired hot water supply boilers shall not be exempted from the requirements of this part on the basis of size or heat input.
(d) Exhaust gas type boilers shall be restricted to a working pressure equal to or less than 103 kPa gage (15 psig) and an operating temperature equal to or less than 454 °C (850 °F). The design temperature of parts exposed to the exhaust gas must be the maximum temperature that could normally be produced by the source of exhaust gas. This temperature shall be verified by testing or by the manufacturer of the engine or other equipment producing the exhaust.
(e) Heating boilers whose operating conditions are within the service restrictions of § 53.01-10(b)(1) may be constructed in accordance with section I of the ASME Boiler and Pressure Vessel Code (incorporated by reference; see 46 CFR 53.01-1). In addition, these heating boilers must:
(1) Be stamped with the appropriate ASME Code symbol in accordance with PG-104 through PG-113 of section IV of the ASME Boiler and Pressure Vessel Code;
(2) Meet the service restrictions of § 53.01-10(b)(2) if made of cast iron;
(3) Have safety valves which meet the requirements of § 52.01-120 of this subchapter;
(4) If a hot water supply boiler, have a temperature relief valve or a pressure-temperature relief valve in accordance with § 53.05-2(c);
(5) If automatically controlled, meet the applicable requirements in part 63 of this subchapter; and
(6) Meet the inspection and test requirements of § 53.10-3.
(f) Controls and miscellaneous accessories. Refer to part 63 of this subchapter for the requirements governing controls and miscellaneous accessories.
