ASME Section VI

The purpose of ASME Section VI is to promote safety in the use of steam heating, hot water heating, and hot water supply boilers that are directly fired with oil, gas, electricity, coal, or other solid and liquid fuels. These guidelines are intended for use by those directly responsible for operating and maintaining heating and hot water supply boilers. These guidelines apply only to boilers subject to the service restrictions of ASME Section IV, HG-101 of the ASME Boiler and Pressure Vessel Code, as follows:

(a) steam boilers for operation at pressures not exceeding 15 psi (100 kPa)

(b) hot water heating and hot water supply boilers for operation at pressures not exceeding 160 psi (1 100 kPa) and/or temperatures not exceeding 250°F (120°C)

These guidelines apply to the boiler proper and to pipe connections up to and including the valve or valves as required by the Code. Guidelines are also provided for operation of auxiliary equipment and appliances that affect the safe and reliable operation of heating boilers. The use of the word “shall” in these Guidelines reflects the mandatory nature of the Section IV requirements. The reader should consult the latest edition of Section IV for the current requirements.
