Overview:

Gas-fired appliances are designed, built, and installed for various processes. The supply of gas, the combustion process, and the disbursement of the energy produced must be done safely and efficiently. This is accomplished with the use of controls and control systems. The types, concepts, and operations for these controls are numerous: they encompass manual, automatic, electrical, mechanical, electronic (the most common), and sometimes digital applications. This Unit gives an overview of how gas systems are controlled and how various components are used to start, stop, and sequence their operation in such a way as to ensure that the equipment is working correctly.

Learning Objectives:

At the end of this unit you will be able to:

• Describe the fundamentals of controls
• Describe and troubleshoot control circuits
• Service and troubleshoot controls
