This course is designed to enable the student to learn the basic principles of heating and heating systems, with a focus on gas fired and oil fired warm air furnaces. Topics to be covered include the three methods of heat transfer; combustion and the by-products of combustion; fuel used in heating; forced-air furnaces; monitoring and measuring manifold pressure on a gas furnace; major components of an oil furnace; components of an electric furnace; and performing basic preventative procedures. Course Objectives:1. explain the three methods by which heat is transferred and note examples; 2. describe how combustion occurs and identify the by-products of combustion; 3. identify the various types of fuels used in heating; 4. identify the major components and accessories of a forced-air furnace and explain the function of each component; 5. demonstrate the ability to state the factors that must be considered when installing a furnace; 6. identify the major components of a gas furnace and describe how each performs; with supervision use a manometer to measure and adjust manifold pressure on a gas furnace; 7. identify the major components of an oil furnace and describe how each performs; and 8. describe how an electric furnace works, and with supervision perform basic furnace preventative maintenance procedures.
