This is a 2-hour long lecture-lab combination class. Some of the time will be spent lecturing, using academic course materials. The rest of the time will be spent in a lab setting, practicing the application of skills learned in theory. This class will provide a broad exposure to gas heating equipment. It will include their construction, operation, troubleshooting, installation and service needs. Equipment will be explored, taken apart, reassembled, and manipulated. We will discuss the gas heating equipment as well as the mechanical, fuel combustion, and electrical service in depth. This course ties together how the installation of this equipment affects the efficiency, all-around performance, and length of service this equipment will have for the end user. This class may require participation in several field trips for further understanding of the profession. Prerequisites: 1st semester HVAC/R, or 1st year Electrical. (S)
