This first course in a four-course series on heating and ventilating for the secondary/postsecondary level is one of a number of military-developed curriculum packages selected for adaptation to vocational instruction and curriculum development in a civilian setting. The four lessons in the course cover these topics: (1) Blueprints and Specifications, (2) Tools and Piping, (3) Electricity, and (4) Insulation and Refractory. Designed for student self-study and evaluation, the course materials consist of a text and a student workbook. The text contains the reading assignments and appendixes (pipefitting, valves, and piping symbols; heating symbols; and heating power symbols). Materials found in the workbook are lesson objectives, text assignments, lesson review exercises, answers to the exercises, and a discussion of those answers. A course examination is provided, but no answer key is included. The course may be used for remedial or independent study. (YLB)
