The term thermal fluid heater as used in this part includes any fired automatic auxiliary heating unit which uses a natural or synthetic fluid in the liquid phase as the heat exchange medium and whose operating temperature and pressure do not exceed 204 °C (400 °F) and 225 psig, respectively. Thermal fluid heaters having operating temperatures and pressures higher than 204 °C (400 °F) and 225 psig, respectively, are inspected under subpart 61.05—Tests and Inspections of Boilers. For visual inspection, access plates and manholes shall be removed as required by the marine inspector and the heater and combustion chambers shall be thoroughly cooled and cleaned. [CGD 80-064, 49 FR 32193, Aug. 13, 1984, as amended by CGD 95–027, 61 FR 26002, May 23, 1996] All new installations of thermal fluid heaters must be given a hydrostatic test of 1 Thermal fluid heaters are examined by a marine inspector at the inspection for certification, periodic inspection and when directed by the Officer in Charge Marine Inspection, to determine that the complete unit is in a safe and satisfactory condition. The visual examination includes, but is not limited to, the combustion chamber, heat exchanger, refractory, exhaust stack, and associated pumps and piping. [CGD 80–064, 49 FR 32193, Aug. 13, 1984, as amended by USCG–1999–4976, 65 FR 6501, Feb. 9, 2000] Operational tests and checks of all safety and limit controls, combustion controls, programming controls, and safety relief valves must be conducted by the owner, chief engineer, or person in charge at the inspection for certification, periodic inspection, and when directed by the Officer in Charge, Marine Inspection, to determine that the control components and safety devices are functioning properly and are in satisfactory operating condition. These tests and checks must be conducted in the presence of a marine inspector and must include the following: proper prepurge, burner ignition sequence checks, operation of the combustion controls, limit controls, fluid flow controls, fluid level controls, high temperature control, proper postpurge control, and verification of the flame safeguard. [CGD 88–057, 55 FR 24237, June 15, 1990, as amended by USCG–1999–4976, 65 FR 6501, Feb. 9, 2000] Note: Sections 63.05–90 and 63.10–90 of this chapter may be referenced concerning operating tests.
