Fundamentals of Gas Controls

摘要

Some years back, the American Gas Association (AGA) published a set of Fundamentals booklets covering topics important in servicing most types of gas-fired equipment. Those booklets were as useful as a handy and dependable set of wrenches. In recent years, the AGA has expanded and updated the booklets in a combination textbook-workbook form. The six booklets in the Fundamentals series have grown to become more like books, and they are so valuable for training the service technician that we will be reviewing them one-at-a-time.
