International Fuel and Gas Code and
Master Isometrics 6HR CE

Course Description

The International Fuel Gas Code® (IFGC®) establishes minimum requirements for plumbing systems using prescriptive and performance-related provisions. It is founded on broad-based principles that make possible the use of new materials and new plumbing designs. This course will review the basic provisions for appliance installation, combustion air, venting, fuel gas piping, ducting, ventilation and exhaust. Participants will gain an understanding how these requirements apply to design, plan review and inspection.

An isometric sketch is a two-dimensional drawing that provides plumbers with the most information about piping layout. Being able to create accurate isometric drawings is a difficult, yet valuable tool for any plumbing professional. This course provides plumbers with plans and drawings that require more advanced skills for laying out complicated isometric drawings. Downloadable drawings are included
