Task Descriptor
Heat recovery systems transfer heat from various sources of heat such as gland seals, refrigerant gas, exhaust steam, flash steam, waste water, cooling water and heat recovery ventilators. Steamfitter/pipefitters install, test, maintain, troubleshoot and repair heat recovery systems.
Steamfitters/Pipefitters are responsible for the installation and maintenance of piping, associated components and equipment for these systems. Maintenance is done on a regular schedule or on an emergency basis to ensure the integrity of the piping system. Steamfitters/Pipefitters are also responsible for diagnosing, locating and repairing or replacing equipment and material. Repairs are performed on an as-needed basis.
Industry Expected Performance
The task must be performed according to the applicable jurisdictional codes and standards. All health and safety standards must be respected. Work should be done efficiently and at a high quality without material waste or environmental damage. All requirements of the manufacturer, client specifications and the AHJ must be met.
At a journeyperson level of performance, all tasks must be done with minimal direction and supervision.
