What is the primary function of the Boiler installer license class 2B?

The primary function of the Boiler installer license class 2B is to install low-pressure boilers of any capacity or firing rate. This license is specifically designed to ensure that individuals responsible for the installation of these types of boilers have the necessary knowledge and skills to do so safely and efficiently. Low-pressure boilers are commonly used in various applications, including residential heating and some commercial processes, and they operate under less stringent safety regulations compared to high-pressure systems.

Having this license ensures that the installer is aware of the codes and standards that govern low-pressure boiler installations, including aspects of safety, efficiency, and proper equipment handling. This enhances the overall safety and reliability of boiler operations in settings where they are deployed, preventing potential hazards associated with improper installation.

Other options describe functions outside the scope of the 2B license. Installing nuclear heat source boilers pertains to advanced and specialized training not covered under this class. Non-boiler external piping may involve different skills and licensing that are not directly related to the boiler itself. Lastly, high-pressure boiler installations require a different level of certification and expertise that the 2B license does not encompass, as it is specifically tailored to low-pressure systems.
