A. Describe the properties of steam.
B. Describe how steam works in a heating system.
C. Review the use of the one-pipe heating system.
D. Compare the operation of the two-pipe system to the one-pipe system.
E. Distinguish between condensate pumps and boiler pumps.
F. Describe the function of the pressuretrol.
G. Explain the types and operation of steam traps in the heating system.
H. Describe the importance of steam piping layout and pipe sizing and demonstrate the different types of expansion joints.
I. Identify and compare the different types of heat transfer devices.
J. Identify and differentiate among various types of steam boilers.
