What code contains guidelines for the care and operation of heating boilers?

The guidelines for the care and operation of heating boilers are found in ASME Section IV. This section of the American Society of Mechanical Engineers (ASME) focuses specifically on the rules for the construction and care of heating boilers. It addresses aspects such as the design, materials, fabrication, testing, and performance of both steam and hot water heating boilers, providing essential information to ensure safe and efficient operation.

ASME Section VI primarily deals with the care and operation of industrial boilers and is focused on the operation aspect rather than the specific care guidelines. On the other hand, CSA B51 is related to the standards for boilers and pressure vessels but does not focus solely on heating boilers. CSA B52 pertains to mechanical refrigeration systems and does not cover the operation of heating boilers at all.

Overall, ASME Section IV is the correct reference for maintenance and operational guidelines specifically tailored to heating boilers, making it crucial for personnel involved in their operation and maintenance to be familiar with this code.
