(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 Code. 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, Heating Boilers, of the ASME Code shall be used except as noted otherwise in this part.

(a) General. The service restrictions and exceptions shall be as indicated in this section in lieu of the requirements in HG–101 of the ASME Code.
(c) Hot water supply boilers. (1) Electrically fired hot water supply boilers which have a capacity not greater than 454 liters (120 gallons), a heat input not greater than 58.6 kilowatts (200,000 B.t.u. per hour), and are listed as approved under Underwriters' Laboratories Standard 174 or 1453 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.
(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 Code. In addition, these heating boilers must:
(1) Be stamped with the appropriate ASME Code symbol in accordance with PG–104 through PG–113 of the ASME Code;
